Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion that may be readily understood.

A folding screen device (e.g., a folding screen phone) refers to an electronic device having a folding screen that is a unitary screen that can be folded or unfolded. Accordingly, the folding screen device has two device states, namely a folded state and an unfolded state. The folding modes of the folding screen mobile phone are two, namely an outward folding mode and an inward folding mode.

For a folding screen mobile phone in which the folding mode is the outward folding mode, when the folding screen is in an unfolded state (as shown in fig. 1A), all the area of the folding screen can be used for displaying data, such as displaying a shooting interface. When the folding screen is in a folded state (as shown in fig. 1B), a partial area of the folding screen (such as a main screen 11 or a secondary screen 10) is used for displaying data, wherein the main screen 11 is opposite to the secondary screen 10, the secondary screen 10 can be on the same side as a rear camera of the folding screen mobile phone, and the main screen 11 and the secondary screen 10 form the folding screen. Wherein the device states may be switched between. For example, a folding screen phone may be switched from an unfolded state to a folded state. Specifically, when the folding screen mobile phone is in an unfolded state, the user folds the folding screen mobile phone (as shown in fig. 1C, folds the folding screen mobile phone outwards along the folding edge, that is, folds the folding screen mobile phone towards the opposite surface on which the user interface can be displayed), so as to form the folding screen mobile phone in a folded state. Similarly, the folding screen mobile phone can be switched from an unfolding state to a folding state.

Illustratively, when the folding angle θ (i.e., the angle between two portions of the screen folded along the folding edge) of the folding screen (θ as shown in fig. 1C above) can range in value from [180 °,360 ° ]. When theta is within the range of 180 degrees and X1, the folding screen mobile phone can be determined to be in an unfolding state. When the folding screen mobile phone is in the folded state, the folding screen mobile phone can be determined to be in the folded state, wherein X1 is a first preset angle threshold value, X1 can be set before delivery of the folding screen mobile phone, can be set in the folding screen mobile phone by a user, can be determined by the folding screen mobile phone based on the using habit of the user, and is not limited, for example, X can be set to 265 DEG, 270 DEG or 275 DEG and the like, and the folding screen mobile phone is determined to be in the unfolded state when the folding angle theta of the folding screen is larger than or equal to 180 DEG and smaller than or equal to 270 DEG, and is determined to be in the folded state when the folding angle theta of the folding screen is larger than 270 deg.

For a folding screen phone in which the folding mode is an inward folding mode, the folding screen phone may include an inner screen (an inner screen 12 as shown in fig. 1D) and an outer screen (an outer screen 13 as shown in fig. 1E), the inner screen is a folding screen, the inner screen and the outer screen face away, and the size of the inner screen is larger than that of the outer screen. The inner screen may be used to display data with the folding screen in an unfolded state. The outer screen may be used to display data with the folding screen in a folded state. The device states of the folding screen mobile phone can be switched. For example, a folding screen phone may be switched from an unfolded state to a folded state. Specifically, when the folding screen mobile phone is in the unfolded state, the user may fold the folding screen mobile phone according to the folding manner shown in fig. 1D, so as to form the folding screen mobile phone in the folded state. Similarly, the folding screen mobile phone can be switched from an unfolding state to a folding state.

The inner screen may be regarded as a main screen, and the outer screen may be regarded as a sub-screen.

Note that, the folding manner of the folding screen mobile phone may be left and right folding as shown in fig. 1C or fig. 1D, or may be up and down folding, which is not limited in the embodiment of the present application. In addition, the number of the folding edges corresponding to the folding screen mobile phone may be one as shown in fig. 1A, fig. 1C and fig. 1D, or may be a number greater than 1, for example, two, which is not limited in the embodiment of the present application.

In some embodiments, for the folding-screen mobile phone (called as an external folding-screen mobile phone for short) in which the folding mode is the external folding mode, the external folding-screen mobile phone is in a folded state, and the main screen and the auxiliary screen of the external folding-screen mobile phone are opposite. The main screen is a screen displaying picture content, and the auxiliary screen is a screen not displaying picture content, namely, the auxiliary screen is always in a screen-off state under the condition that the external folding screen mobile phone is in a folding state.

However, if the secondary screen is in the screen-off state all the time, the secondary screen cannot be used by the user, so that waste of screen resources is caused, the flexibility of screen use is low, and the use experience of the user is affected.

In some embodiments, in order to improve flexibility of screen use, the out-folded screen mobile phone may monitor a triggering operation of a user for the secondary screen when the out-folded screen mobile phone is in a folded state, and a main screen of the out-folded screen mobile phone is not locked and is on. And then, under the condition that the triggering operation of the user is detected, if the triggering operation is a preset operation, displaying target information on the auxiliary screen, wherein the target information can be preset information of the user or can be determined by the out-folded screen mobile phone according to the habit of the user, and the method is not particularly limited. Therefore, the display content of the auxiliary screen can be flexibly controlled, and the utilization rate of the auxiliary screen is further improved.

The preset operation may be that the user continuously taps the secondary screen of the out-folded screen mobile phone for a preset number of times (such as 2 times, 3 times, etc.), or the user performs finger sliding on the secondary screen of the out-folded screen mobile phone according to a preset direction (such as from left to right, from bottom to top, etc.), or the user performs sliding operation after tapping on the secondary screen of the out-folded screen mobile phone for one time, etc. Or, the preset operation can be the operation of knocking, sliding or dragging the main screen of the outward folding screen mobile phone and any combination thereof. It may be understood that the preset operation may be preset, specifically, any preset operation, which is not limited in this embodiment of the present application. The electronic device may detect the preset operation by an acceleration sensor, for example. The foregoing clicking operation may be, for example, an operation of clicking the secondary screen with a finger, an operation of clicking the secondary screen with a knuckle, or the like, and is not particularly limited. The tapping operation may be to tap the secondary screen for a preset number of times within a preset duration, where the preset duration may be 0.5 seconds, 1 second, 2 seconds, or the like, which is not limited in the embodiment of the present application.

For example, in the process that the user uses the folding mobile phone, if a scene which needs to show related information to the outside is encountered, the user can double-click the secondary screen. After that, the external folding screen mobile phone can display related information on the auxiliary screen for external viewing or use under the condition of keeping the original picture content of the main screen unchanged, so that the original picture content of the main screen can be kept, the related information can be displayed outside without turning the mobile phone screen by a user, and convenience is provided for the user. For example, referring to fig. 2, in a case where the main screen (e.g., (a) interface in fig. 2) of the out-folded screen mobile phone is displaying the content of the electronic book, if the sub-screen of the out-folded screen mobile phone is tapped twice consecutively by the user, the out-folded screen mobile phone may display the ride code information on the sub-screen (e.g., (b) interface in fig. 2) so as to facilitate the code swinger to scan the ride code. For another example, in the case where the main screen of the out-folded mobile phone is displaying the content of the electronic book, if the user is at the entrance of the company and needs to present the electronic tablet to the security, the user may make three continuous taps on the sub-screen of the out-folded mobile phone. And then, under the condition that the external folding screen mobile phone detects continuous three-time knocking operation aiming at the auxiliary screen, the external folding screen mobile phone can directly display the work card information on the auxiliary screen so as to facilitate security to check the work card information.

In order to display target information more accurately by the auxiliary screen, the main screen can display corresponding prompt information when the auxiliary screen displays the target information, wherein the prompt information is used for indicating the display state of the target information, so that a user can know the display state of the target information clearly conveniently, whether the target information is displayed or not is checked in a mode of turning over the screen, and the use experience of the user is improved. For example, as shown in fig. 3, in the case that the main screen (such as the (a) interface in fig. 3) of the out-folded mobile phone is displaying the content of the electronic book, if the payment code needs to be presented for payment at this time, the user may make two continuous taps on the sub-screen (such as the (b) interface in fig. 3) of the out-folded mobile phone. And then, under the condition that the external folding screen mobile phone detects continuous double-tap operation aiming at the auxiliary screen, the external folding screen mobile phone can directly display the payment code on the auxiliary screen. In addition, while the secondary screen displays the payment code, the primary screen may display a floating window 302 on the current interface 301, where the floating window 302 includes two-dimensional code information, a display state of the two-dimensional code, and a drop-down control 3025. The two-dimensional code information includes at least one of an application name (e.g., first application 3023), an application icon (e.g., icon 3021 of the first application), and a two-dimensional code type (e.g., first payment code 3024) corresponding to the two-dimensional code. By way of example, the two-dimensional code type may be a payment code, a collection code, a riding code, an identification code, various two-dimensional codes that may occur in the future, and the like, which is not limited in the embodiment of the present application. The display state may include a back screen bright code state 3022 and a bright code failure state, where the back screen bright code state 3022 is used to indicate that the back screen successfully displays the two-dimensional code, and the bright code failure state is used to indicate that the back screen fails to successfully display the two-dimensional code.

Fig. 3 (b) is a schematic diagram of a user interface for displaying the first payment code of the first application on the secondary screen. As can be seen in fig. 3 (b), the background of the back screen is black, and the area 303 displaying the first two-dimensional code of the first application is white. The field 303 may include a payment bar code 3031, a payment two-dimensional code 3032, and text 3033 indicating that the number of the first payment code is displayed. The text 3033 may be, for example, "click-to-view first payment code number," or the like, and the embodiment of the present application does not limit the specific content of the text. Illustratively, the user interface of the first payment code of the first application may also include an explanation 304 regarding the first payment code. The description 304 may include, for example, an icon 3041 of the first application and a name 3042 of the displayed two-dimensional code (e.g., the first payment code of the first application).

Optionally, the drop-down control 3025 may display more selectable two-dimensional code types in the floating window 302, and the selected two-dimensional code may be displayed on the secondary screen of the out-folded mobile phone. Specifically, if the drop-down control is clicked by the user, the floating window can also display two-dimensional code information corresponding to other applications. And then, responding to the clicking operation of a user aiming at any two-dimensional code information, and displaying the two-dimensional code corresponding to the clicked two-dimensional code information on the auxiliary screen by the out-folded screen mobile phone so as to realize the switching function of the two-dimensional code of the auxiliary screen. For example, referring to fig. 4, if a drop-down control 3025 displayed on a main screen (e.g., the (a) interface in fig. 3) of the out-folded screen mobile phone is clicked by the user, the floating window 302 may display two-dimensional code information to be switched. The two-dimensional code information to be switched may include an application icon to be switched and a two-dimensional code corresponding to the application to be switched, for example, please refer to an interface (a) in fig. 4, the two-dimensional code information to be switched may include a second application icon 3027 and a second two-dimensional code 3028 using a second application, or the two-dimensional code information to be switched may include a third application icon 3029 and a third two-dimensional code 30210 using a third application. Meanwhile, the pull-down control 3025 is replaced with a pull-up control 3026, where the pull-up control 3026 is used for retracting the deployed floating window 302, that is, retracting the two-dimensional code information to be switched.

Then, if the region corresponding to the "second two-dimensional code of the second application" in the floating window 302 is clicked by the user, the second two-dimensional code of the second application is displayed on the secondary screen (e.g. the interface (b) in fig. 4) of the out-folded screen mobile phone. It can be appreciated that in the interface (b) of fig. 4, the second two-dimensional code display area 307 may include therein a payment bar code 3071, a payment two-dimensional code 3072, and a letter 3073 indicating that the number of the second two-dimensional code is displayed. The text 3073 may be, for example, "a touch can view a second two-dimensional code number", and the embodiment of the present application does not limit the specific content of the text. Illustratively, the user interface displaying the second two-dimensional code of the second application may also include an explanation 308 about the second two-dimensional code. The description 308 may include, for example, the icon 3081 of the second application and the displayed two-dimensional code name 3082. The name 3082 of the two-dimensional code may be "second application second two-dimensional code", or "second application second payment code", etc., and the text description of the name of the two-dimensional code is not limited in this embodiment of the present application.

In some embodiments, under the condition that the floating window on the main screen displays the scanning information, if the user performs the knocking operation on the auxiliary screen again, a new floating window is displayed on the main screen of the out-folded screen mobile phone, and the new floating window is used for representing two-dimensional code information corresponding to the two-dimensional code to be displayed on the auxiliary screen when the user knocks again. That is, two floating windows are displayed on the main screen of the out-folded screen mobile phone, so that the floating windows are repeatedly displayed, the user is bothered, and the user experience is low. Illustratively, as shown in fig. 5, the home screen of the out-folded mobile phone is displayed with a floating window 302C and a floating window 302E. The floating window 302C is a floating window generated by scanning the two-dimensional code on the secondary screen last time. The hover window 302E is a new hover window generated by the user again performing a tap operation.

In one implementation, as shown in fig. 6, the above process of displaying a floating window on the home screen may specifically include: under the conditions that the external folding screen mobile phone is in a folding state, the main screen of the external folding screen mobile phone is not locked and is on, if the auxiliary screen of the external folding screen mobile phone is knocked by a user, the external folding screen mobile phone can start an auxiliary screen service application (or called an auxiliary screen service). The secondary screen service application may then send a query indication to the intelligent intermediate station. And then, under the condition that the intelligent center station receives the query instruction sent by the auxiliary screen service application, combining the user habit, and determining target two-dimensional code information, wherein the target two-dimensional code information comprises a target two-dimensional code, an application name corresponding to the target two-dimensional code and a type (or a two-dimensional code type) of the target two-dimensional code. And then, the auxiliary screen service application can draw the floating window displayed on the main screen according to the target two-dimensional code information so as to finish the display of the floating window. And then, if the two-dimensional code on the secondary screen is scanned, the secondary screen service application can delete the floating window on the primary screen under the condition that the display time is longer than the preset time, namely, the floating window is not displayed.

Optionally, in the case that the secondary screen is tapped by the user and the primary screen does not display the floating window, that is, if the user performs the target operation, the out-folded screen mobile phone may trigger the recycling process, that is, the two-dimensional code is not displayed on the secondary screen and the floating window is not displayed on the primary screen. However, if the user performs the target operation in the process of determining the target two-dimensional code information by the out-folded screen mobile phone, it is indicated that the user does not want to display the target two-dimensional code. Therefore, the out-turned screen phone can trigger the recycling process. However, the out-folded screen mobile phone does not determine the target two-dimensional code information, and the floating window and the target two-dimensional code are not drawn. Therefore, even if the above secondary screen service application triggers the recovery process, the recovery process does not break the subsequent floating window drawing process, and the recovery process cannot delete the floating window displayed on the primary screen and the target two-dimensional code displayed on the secondary screen. That is, the floating window is displayed on the main screen of the out-folded screen mobile phone, and the target two-dimensional code is displayed on the auxiliary screen of the out-folded screen mobile phone.

For example, as shown in fig. 7, in the case that the out-folded mobile phone is in a folded state, the main screen of the out-folded mobile phone is not locked and is on, if the sub-screen of the out-folded mobile phone is tapped by the user, the out-folded mobile phone may start the sub-screen service application. The secondary screen service application may then send a query indication to the intelligent intermediate station. And then, under the condition that the intelligent middle station receives the inquiry instruction sent by the auxiliary screen service application, combining the habit of the user, and determining the target two-dimensional code information. And if the target two-dimensional code information is determined, the user executes target operation to trigger the secondary screen service to exit the process. And then, the secondary screen service application can trigger a recovery flow, namely deleting the floating window displayed on the main screen and the target two-dimensional code displayed on the secondary screen.

After the target two-dimension code information is determined, the secondary screen service exit flow is already executed, that is, the secondary screen service application can default to continue to execute the subsequent flow, that is, the secondary screen service application can continue to draw the floating window displayed on the main screen according to the target two-dimension code information, so that the display of the floating window is completed. That is, after the user performs the target operation, the out-folded screen mobile phone can still display the floating window on the main screen, and the floating window cannot be deleted in time according to the secondary screen service exit flow, so that the use experience of the user is affected.

Therefore, in order to timely delete the floating window of the main screen, the embodiment of the application provides a display control method and electronic equipment. In the method, in response to a triggering operation of a user on a secondary screen, the folding screen device can judge whether the triggering operation is a preset operation, and under the condition that the triggering operation is the preset operation, the folding screen device can combine user behavior data to determine target two-dimensional code information. Then, the folding screen device may determine whether a preset condition is satisfied, and in case the folding screen device satisfies the preset condition, the folding screen device may draw the floating window. The preset condition may include one of the folding screen device being in a folded state, the main screen being in a bright screen state, and the user not performing a target operation or performing a target operation in a previous execution of the back screen bright code flow. The handset may then display a floating window on the home screen.

In the embodiment of the application, before the floating window is drawn, the folding screen device can judge whether the folding screen device meets the preset condition, and if the folding screen device meets the preset condition, the floating window can be drawn continuously; if the folding screen device does not meet the preset conditions, the floating window is not drawn, so that the floating window can be timely deleted, the condition that memory resources are occupied due to the fact that the generated floating window cannot be deleted is reduced, waste of the memory resources is reduced, drawing resources of the floating window can be saved, and user experience is improved.

The software system of the electronic device 200 may employ a layered architecture, an event driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. In this embodiment, taking an Android system with a layered architecture as an example, a software structure of the electronic device 200 is illustrated.

Fig. 9 is a software configuration block diagram of the electronic device 200 of the embodiment of the present application.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer (abbreviated as application layer), an application framework layer (abbreviated as framework layer), an Zhuoyun row (Android run) and system library, and a Kernel (Kernel) layer (or referred to as driver layer). The application layer may include a series of application packages.

It will be appreciated that the layers and the components contained in the layers in the structure shown in fig. 9 do not constitute a specific limitation on the electronic device 200, i.e. the folding screen device. In other embodiments of the present application, the structure may include more or fewer layers than shown, and more or fewer components may be included in each layer, as the present application is not limited.

Based on the electronic device described in the above exemplary embodiments, the embodiment of the present application provides a display control method. The method can be applied to a scene that the electronic equipment with the outward folding and folding screen is in a folding state. The method of the embodiment of the present application will be described below by taking an electronic device as an example of an out-folded mobile phone. Specifically, as shown in fig. 10, the display control method may include S201 to S211.

S201, the out-folded screen mobile phone receives touch operation of a user on the auxiliary screen.

The touch operation refers to an operation performed when a finger or a finger joint of a user touches the sub-screen. The touch operation may be, for example, a clicking operation for any position in the secondary screen, a sliding operation for the secondary screen, or the like, which is not particularly limited. In an example, the sliding operation may be a single-finger sliding operation, a multi-finger sliding operation, or the like. In another example, the sliding operation may be an upward sliding operation for the sub-screen, a leftward sliding operation for the sub-screen, or the like.

In this embodiment, only when the folding mobile phone is in the folded state, the main screen is not locked, and the screen is on, the folding mobile phone receives the touch operation of the user on the auxiliary screen, that is, if the folding mobile phone is in the unfolded state, or if the main screen is in the locked state or the deactivated state, the folding mobile phone does not receive the touch operation of the user on the auxiliary screen. Therefore, the situation that the target two-dimensional code is displayed by mistake due to the fact that the user touches the auxiliary screen by mistake can be avoided, the information security of the user can be protected, and important information of the user is prevented from being revealed under the condition that the user is unaware.

It should be noted that, before the touch operation is not received by the out-folded screen mobile phone, the main screen of the out-folded screen mobile phone displays a first user interface, where the first user interface includes an interface of a first application. For example, referring to the interface (a) in fig. 2 again, the first user interface is an interface displaying electronic book content, and the first application is an electronic book application. Meanwhile, the auxiliary screen of the external folding screen mobile phone is in a screen-off state.

S202, the out-folded screen mobile phone judges whether the touch operation is a preset operation or not.

In some embodiments, after receiving the touch operation of the user on the secondary screen, the out-folded screen mobile phone may determine whether the touch operation is a preset operation, if the touch operation is not the preset operation, which indicates that the user may touch the secondary screen by mistake or want to trigger other events, so the out-folded screen mobile phone may execute S203 to wait for the next touch operation of the user on the secondary screen. If the touch operation is the preset operation, it indicates that the user wants to display the target two-dimensional code on the secondary screen, so the out-folded screen mobile phone may execute S204 to determine the target two-dimensional code information. The target two-dimensional code may be determined by the out-folded screen mobile phone according to a user using habit (or referred to as user behavior data), may be preset by the user, may be default by the out-folded screen mobile phone, and is not specifically limited.

The preset operation may be a default operation (for example, clicking the secondary screen twice continuously) of the out-folded screen mobile phone, or an operation preset by the user according to a use habit of the user, and the like, which is not particularly limited. The preset operation may be, for example, a user continuously taps the secondary screen of the out-folded screen mobile phone for a preset number of times (e.g., 2 times, 3 times, etc.), or the user may perform finger sliding on the secondary screen of the out-folded screen mobile phone according to a preset direction (e.g., from left to right, from bottom to top, etc.), or the user may perform sliding operation after tapping on the secondary screen of the out-folded screen mobile phone once. Or, the preset operation can be the operation of knocking, sliding or dragging the main screen of the outward folding screen mobile phone and any combination thereof.

In one implementation manner, the preset operations may be multiple, and different preset operations correspond to different display contents. For example, if the preset operation is that the user continuously clicks the secondary screen of the out-folded screen mobile phone for 2 times, the out-folded screen mobile phone can display the target two-dimensional code on the secondary screen. For another example, if the user performs finger sliding on the secondary screen of the out-folded screen mobile phone in the left-to-right direction, the out-folded screen mobile phone may display the electronic work board of the user on the secondary screen.

For example, if the touch operation is one of a plurality of preset operations, it is indicated that the user wants to display the display content corresponding to the touch operation on the secondary screen, so that the folded-out screen mobile phone may display the display content corresponding to the touch operation on the secondary screen. If the above touch operation does not belong to any one of the preset operations, it is indicated that the user may touch the secondary screen by mistake or want to trigger other events, so the folded-out screen mobile phone may execute S203 to wait for the next touch operation of the user on the secondary screen.

S203, the out-folded screen mobile phone waits for the next touch operation of the user on the auxiliary screen.

In this application, after determining that the above touch operation is not the preset operation, the folded-out screen mobile phone may wait for the next touch operation of the user on the secondary screen, so as to continuously determine whether the next touch operation of the user is the preset operation.

S204, combining the user behavior data with the out-folded screen mobile phone to determine target two-dimensional code information.

In this application, after determining that the above touch operation is a preset operation, the out-folded screen mobile phone may determine the target two-dimensional code information according to the user behavior data (or referred to as user usage habit data). The target two-dimensional code information may include an application name corresponding to the target two-dimensional code (or an application name called a target application), a type of the target two-dimensional code, and the like. The type of the target two-dimensional code may be, for example, a payment code, a riding code, a collection code, an identification code, various two-dimensional codes possibly occurring in the future, and the like, which is not particularly limited.

The user behavior data are used for indicating the habit of using the application in the folding mobile phone. The user behavior data may include preference (or application usage) of an application in the out-turned screen mobile phone, a two-dimensional code display habit, and the like. The preference of the application indicates the frequency of the application used by the user, and if the user uses the application frequently, the preference of the application is indicated to be higher. It will be appreciated that the user behavior data may be user behavior habit data collected over a period of time. The preset time may be set according to the requirement, for example, the preset time may be 1 day, 1 week, etc.

In an example, if the payment application in the out-folded screen mobile phone includes a first application and a second application, and the usage rate of the first application is higher than that of the second application, that is, the user uses the first application to perform the payment operation frequently, the out-folded screen mobile phone may determine the payment code corresponding to the first application as the target two-dimensional code. Then, if the user performs the preset operation on the secondary screen, it is indicated that the user is about to perform the payment operation, so that the out-folded screen mobile phone can directly display the payment code corresponding to the first application on the secondary screen.

In another example, if the user holding the out-folded screen mobile phone often displays the riding code between 8:00 and 8:30, it is indicated that the user often rides between 8:00 and 8:30, and therefore, the out-folded screen mobile phone can use the riding code as the target two-dimensional code. Then, if the user performs the preset operation on the auxiliary screen between 8:00 and 8:30, the user is about to take a bus, so that the out-folded screen mobile phone can directly display a bus taking code on the auxiliary screen.

In some embodiments, the target two-dimensional code information may be determined according to a touch operation of the user on the secondary screen, that is, the target two-dimensional code information corresponding to different touch operations is different. For example, if the user performs two continuous clicking operations on the secondary screen, the out-turned screen mobile phone may display the payment code of the first application on the secondary screen. For another example, if the user continuously performs three clicking operations on the secondary screen, the out-folded screen mobile phone may display the riding code of the third application on the secondary screen.

S205, the out-folded screen mobile phone judges whether the target process exits.

Specifically, after the target two-dimensional code information is determined, the out-folded screen mobile phone can judge whether the target process exits. The target process is a process triggered based on the preset operation, namely a process corresponding to the process when the external folding screen mobile phone executes the auxiliary screen bright code program. The process is a running activity of a program with independent functions with respect to a certain data set.

In some embodiments, if the target process has been exited, it is indicated that the out-folded mobile phone may be in an abnormal scene or the user does not want to display the target two-dimensional code, so in order to avoid the waste of memory resources caused by drawing the target two-dimensional code, the out-folded mobile phone may execute S206, that is, not display the target two-dimensional code on the secondary screen. If the target process does not exit, it indicates that the out-folded mobile phone is in a normal scene, that is, the out-folded mobile phone is still in a folded state, the main screen is not locked and is on, and the user does not perform any exit operation, so that the out-folded mobile phone can execute S207.

For example, if the out-turned screen phone responds to an abnormal event, the out-turned screen phone may exit the target process. The abnormal event may be that the user switches the folded mobile phone from a folded state to an unfolded state in the process of determining the target two-dimensional code information by the folded mobile phone, or switches the main screen of the folded mobile phone from a bright screen state to a screen-off state in the process of determining the target two-dimensional code information by the folded mobile phone, or monitors at least two exit events in the process of displaying the historical two-dimensional code by the folded mobile phone. The historical two-dimensional code is a two-dimensional code displayed before the target two-dimensional code, namely, the two-dimensional code displayed by the last secondary screen in response to the preset operation of the user.

In an example, the exit event may be receiving a first operation of the user, which may be an operation of the switch control being clicked by the user. The switching control is used for switching the history two-dimensional code displayed on the auxiliary screen to the main screen for display, that is, if the switching control is clicked by a user, the out-folded screen mobile phone can display the history two-dimensional code on the main screen. For example, referring to fig. 11, the interface (a) in fig. 11 is a user interface of the primary screen in the current situation, and the interface (b) in fig. 11 is a user interface of the secondary screen in the current situation, that is, a floating window 302 is displayed on the primary screen, where the floating window 302 includes a switching control a, and a history two-dimensional code is displayed on the secondary screen. If the switch control a in the floating window 302 is clicked by the user, the secondary screen in the out-folded screen mobile phone will not display the historical two-dimensional code, that is, the secondary screen is in the off-screen state (e.g., (d) interface in fig. 11). And, the out-folded screen mobile phone displays the history two-dimensional code on the main screen (as shown in the interface (c) in fig. 11), that is, the history two-dimensional code is switched from the sub-screen display to the main screen display.

In an example, the exit event may be that the historical two-dimensional code was scanned successfully. It can be understood that if the history two-dimensional code is scanned successfully, it is indicated that the history two-dimensional code is already used by the user, so that the out-folded screen mobile phone does not need to continuously display the history two-dimensional code on the auxiliary screen, the auxiliary screen can be converted from a bright screen state to a screen-off state, or the out-folded screen mobile phone can display prompt information (such as successful scanning) of a first preset time (such as 5 s) on the auxiliary screen, so as to prompt the user that the history two-dimensional code is scanned successfully, and the user can clearly know the scanning state of the two-dimensional code conveniently.

In an example, the exit event may be that a display time of the historical two-dimensional code exceeds a second preset time. It can be understood that if the display time of the history two-dimensional code exceeds the second preset time (for example, 30 s), it is indicated that the history two-dimensional code is not scanned for a long time, so that in order to reduce unnecessary power consumption loss, the out-folded screen mobile phone can not display the history two-dimensional code on the auxiliary screen, that is, exit the display of the history two-dimensional code, convert the auxiliary screen from the bright screen state to the off screen state, so as to reduce the consumption of the electric quantity of the out-folded screen mobile phone and improve the cruising ability of the out-folded screen mobile phone.

In another example, the exit event may be receiving a second operation of the user, where the second operation is used to switch the historical two-dimensional code to the candidate two-dimensional code. The candidate two-dimensional codes refer to two-dimensional codes which are desired to be displayed on the secondary screen by a user, and the candidate two-dimensional codes are any two-dimensional codes in a plurality of two-dimensional codes to be switched. It can be understood that if the history two-dimensional code is switched by the user, it is indicated that the user does not want to display the history two-dimensional code, and the user wants to display a new history two-dimensional code (or called a candidate two-dimensional code) on the secondary screen, so that the folded-screen mobile phone can update and display the new history two-dimensional code on the secondary screen. For example, referring to fig. 3 again, if the drop-down control 3025 is clicked by the user to indicate that the user wants to switch the historical two-dimensional code, the out-folded screen mobile phone may display the two-dimensional code information to be switched on the floating window of the main screen, that is, the main screen of the out-folded screen mobile phone may display the content as displayed on the interface (a) in fig. 4, so that the user may select the historical two-dimensional code to be switched. Then, if the area corresponding to the second two-dimensional code of the second application in the floating window 302 is clicked by the user, it is indicated that the user wants to display the second two-dimensional code on the secondary screen, so that the out-folded screen mobile phone can display the second two-dimensional code of the second application on the secondary screen, that is, the secondary screen of the out-folded screen mobile phone can display the content displayed on the interface (b) in fig. 4.

It can be understood that the primary exit event corresponds to a secondary screen light code flow, if two exit events occur during the process of executing the secondary screen light code program, the out-folded screen mobile phone records the primary exit event, so as to exit when the secondary screen light code program is executed next time, that is, the target two-dimensional code cannot be normally displayed.

S206, the outward folding screen mobile phone does not draw a floating window.

Specifically, after the target process is determined to be exited, the out-folded screen mobile phone does not need to display a floating window on the main screen, that is, the out-folded screen mobile phone does not need to draw the floating window. Therefore, the situation of drawing resource waste caused by drawing the floating window can be reduced, and the drawing resource of the target two-dimensional code is saved.

In some embodiments, after determining that the target process has exited, the out-turned screen phone may execute S203 above to wait for the next touch operation of the user on the secondary screen.

S207, the outward folding screen mobile phone displays a floating window on the main screen and displays a target two-dimensional code on the auxiliary screen.

Specifically, after the target process is determined not to exit, the out-folded screen mobile phone may display a floating window (or referred to as a first floating window) on the main screen, and display the target two-dimensional code on the auxiliary screen. Therefore, the accuracy of displaying the target two-dimensional code and the floating window can be improved, and the situation that the use experience of a user is affected due to the fact that the target two-dimensional code and the floating window are displayed in error is reduced. In addition, because this outer book screen cell-phone can be under the condition that does not influence the main screen and use, show the target two-dimensional code on the auxiliary screen, and can show the display condition of target two-dimensional code with the form of suspension window on the main screen, so, can facilitate the user in time to know the display condition of target two-dimensional code, the convenience of customers carries out corresponding processing, promotes user's use experience.

It will be appreciated that displaying the floating window on the home screen means that the floating window is displayed on the basis of the original first user interface, i.e. the new user interface (or called second user interface) may comprise the interface of the first application as well as the first floating window. The floating window may include at least one of an application name corresponding to the target two-dimensional code, an application icon corresponding to the target two-dimensional code, a type of the target two-dimensional code, and a display state of the target two-dimensional code on the secondary screen. The display state can comprise a back screen bright code state and a bright code failure state, wherein the back screen bright code state is used for indicating that the back screen successfully displays the two-dimensional code, and the bright code failure state is used for indicating that the back screen fails to successfully display the two-dimensional code. In some embodiments, the floating window may further include a drop-down control, where the drop-down control is used to display information of the two-dimensional code to be switched, so that the user can select the two-dimensional code.

As shown in fig. 3, the interface (a) in fig. 3 is the second user interface, and specifically, a floating window 302 is displayed on the main screen, where the floating window 302 includes an application icon (such as an icon 3021 of a first application), a display state of a two-dimensional code (such as a back screen bright code state 3022), an application name (such as a first application 3023), a two-dimensional code type (such as a first payment code 3024), and a drop-down control 3025.

Meanwhile, the interface (b) in fig. 3 is a user interface of the secondary screen, and specifically, the secondary screen displays a target two-dimensional code, that is, a first payment code of the first application. The area 303 displaying the first payment code of the first application may include a payment bar code 3031, a payment two-dimensional code 3032, and a letter 3033 indicating that the number of the first payment code is displayed. Illustratively, the user interface of the first payment code of the first application may also include an explanation 304 regarding the first payment code. The description 304 may include an icon 3041 of the first application and a name 3042 of the displayed two-dimensional code (e.g., the first payment code of the first application).

S208, the out-folded screen mobile phone judges whether the target two-dimensional code on the auxiliary screen is scanned or not.

In some embodiments, after the secondary screen displays the target two-dimensional code, the out-folded screen mobile phone may determine whether the target two-dimensional code on the secondary screen is scanned, and if the target two-dimensional code on the secondary screen is scanned, it indicates that the target two-dimensional code is already used by the user, so the out-folded screen mobile phone executes S209 to display the prompt information on the floating window of the primary screen and/or the secondary screen. If the target two-dimensional code on the secondary screen is not scanned, it indicates that the target two-dimensional code is not used by the user, so the out-folded screen mobile phone may execute S211 to determine whether the target two-dimensional code is displayed for a long time.

The target two-dimensional code being scanned refers to the target two-dimensional code being scanned by a code brushing device, and the code brushing device refers to any electronic device capable of scanning codes, such as a point of sales (POS) terminal, etc.

S209, the out-folded screen mobile phone displays prompt information on a floating window and/or an auxiliary screen of the main screen.

Specifically, after the target two-dimensional code on the secondary screen is determined to be scanned, the out-folded screen mobile phone can directly display prompt information (or called scanning information) on the floating window of the primary screen and/or the secondary screen. Therefore, the scanning state of the target two-dimensional code can be conveniently and clearly known by the user, and the use experience of the user is improved.

The prompt information is used for indicating whether the target two-dimensional code displayed on the auxiliary screen is scanned successfully or not. In an example, the prompt information may be text information of successful code scanning, successful payment, etc., where the text information may be related to the type of the target two-dimensional code. For example, if the type of the target two-dimensional code is an identification code, the text information may be that the code scanning is successful. For another example, if the type of the target two-dimensional code is a payment code, the text information may be successful payment. For another example, if the type of the target two-dimensional code is a receipt code, the text message may be that the receipt was successful. In another example, if the type of the target two-dimensional code is a payment code, the prompt information may further include a payment amount, a payment manner, a payee, and the like. If the type of the target two-dimensional code is a payment code, the prompt information can also include payment amount, payment mode, payment party and the like.

In some embodiments, the out-turned screen handset may display a third user interface on the home screen. The third user interface comprises the interface of the first application and a second floating window. The second floating window comprises first prompt information, an application name corresponding to the target two-dimensional code, a two-dimensional code type and the like.

In other embodiments, the out-turned screen phone may display a second prompt on the secondary screen. The second prompt information may be the same as the first prompt information, or may be different from the first prompt information, and is not particularly limited.

In an example, as shown in fig. 12, if the first payment code of the first application is scanned, text information (such as successful payment) 3035, payment amount (such as 100) 3036, payment method 3037 and payee 3038 are displayed on the secondary screen (such as interface (b) in fig. 12) of the out-folded mobile phone. Meanwhile, a floating window 302C is displayed on a main screen (e.g., the interface (a) in fig. 12) of the out-folded mobile phone, where the floating window 302C may include an icon 302C1 of the first application, text information (e.g., 100 yuan) 302C2 indicating that payment is completed, a name 302C3 of the first application, and a two-dimensional code type (e.g., a first payment code) 302C4.

In another example, as shown in fig. 13, if the second two-dimensional code of the second application is scanned, text information (e.g., successful code scanning) is displayed on a secondary screen (e.g., the interface (b) in fig. 13) of the out-folded mobile phone. Meanwhile, a floating window 302D is displayed on a main screen (e.g., an interface (a) in fig. 13) of the out-folded screen mobile phone, where the floating window 302D may include an icon 302D1 of the second application, text information 302D2 indicating that the scanned code is completed, a name 302D3 of the second application, and a two-dimensional code type (e.g., a second two-dimensional code) 302D4.

It should be understood that the floating window displayed on the interface (a) in fig. 12 and the interface (a) in fig. 13 is merely an example, and is not limited to the embodiment of the present application. In a specific implementation, the floating window may display other interface elements or content, which is not limited by the embodiments of the present application.

In one implementation, since the secondary screen is a display screen facing away from the user, that is, the content displayed on the secondary screen cannot be directly viewed by the user, the user may need to turn over the folded-out screen mobile phone, so that the user can view the prompt information displayed on the secondary screen. Therefore, in order to reduce the occurrence of the condition of large electric quantity loss caused by the fact that the auxiliary screen displays the prompt information, the outward folding screen mobile phone can only display the prompt information on the suspension window of the main screen, so that unnecessary power consumption loss can be reduced, and the cruising ability of the outward folding screen mobile phone is improved.

S210, deleting the prompt information by the out-folded screen mobile phone under the condition that the display time of the prompt information is longer than a first preset time.

In the application, after the prompt information is displayed, the external folding screen mobile phone can acquire the display time of the prompt information, if the display time of the prompt information is not longer than the first preset time, the user is not likely to know the code scanning state of the target two-dimensional code, so that the external folding screen mobile phone can continuously display the prompt information until the display time of the prompt information is longer than the first preset time, and the external folding screen mobile phone can delete the prompt information, so that the user can be guaranteed to clearly know the code scanning state of the target two-dimensional code. If the display time of the prompt information is longer than the first preset time, the user is informed that the scanning state of the target two-dimensional code is clearly known, so that the out-folded screen mobile phone can delete the prompt information in order to reduce unnecessary power consumption loss.

The first preset time may be set by a time (timer), for example, the first preset time may be 3s, 5s, or the like. It will be appreciated that the timer corresponds to a timer.

In some embodiments, after determining that the out-folded screen mobile phone displays the prompt information on the floating window of the main screen, if the display time of the prompt information is longer than the first preset time, the out-folded screen mobile phone may directly delete the floating window. Therefore, the cleanliness of the main screen interface can be improved, and the integrity of the display content of the main screen interface is ensured.

In other embodiments, after determining that the out-folded screen mobile phone displays the prompt information on the secondary screen, if the display time of the prompt information is longer than the first preset time, the out-folded screen mobile phone may directly switch the secondary screen from the bright screen state to the off screen state. Therefore, the consumption of the electric quantity of the outward folding mobile phone can be reduced, and the cruising ability of the outward folding mobile phone is improved.

S211, if the display time of the floating window is longer than the second preset time, deleting the floating window displayed by the main screen and deleting the target two-dimensional code displayed by the auxiliary screen by the out-folded screen mobile phone.

In the application, after determining that the target two-dimensional code on the secondary screen is not scanned, the out-folded screen mobile phone can obtain the display time of the floating window (or the display time of the target two-dimensional code). It can be understood that the floating window and the target two-dimensional code are displayed at the same time, that is, the display time of the floating window is the same as the display time of the target two-dimensional code, so that the out-folded screen mobile phone can acquire the display time of the floating window, the display time of the target two-dimensional code, and the display time of the floating window and the display time of the target two-dimensional code at the same time, thereby improving the accuracy of determining the display time.

In an example, if the display time of the floating window is not longer than the second preset time, it indicates that the user may not scan the target two-dimensional code, so the mobile phone may continue to display the target two-dimensional code and the floating window until the display time is longer than the second preset time or the target two-dimensional code is scanned successfully, and the out-folded mobile phone may delete the floating window displayed by the main screen.

In another example, if the display time of the floating window is longer than the second preset time, it is indicated that the target two-dimensional code is not scanned for a long time, so in order to reduce unnecessary power consumption loss, the out-folded screen mobile phone may delete the floating window displayed by the main screen and delete the target two-dimensional code displayed by the auxiliary screen, that is, convert the auxiliary screen from the bright screen state to the off screen state, so that not only can the cleanliness of the main screen interface be improved, the integrity of the display content of the main screen interface be ensured, but also the auxiliary screen can be placed in the off screen state again, thereby reducing the consumption of the electric quantity of the out-folded screen mobile phone and improving the cruising ability of the out-folded screen mobile phone.

The second preset time may be set by a timer, for example, the second preset time may be 30 seconds, 1 minute, or the like. It is understood that the first preset time and the second preset time may be the same or different, and are not particularly limited.

In some embodiments, in the case of receiving a touch operation of a user on the secondary screen, a system service in the out-folded screen mobile phone may perform event analysis according to the touch operation, so as to start the secondary screen service application in the case that the touch operation is a preset operation. The following will describe in detail how the system service in the out-folded mobile phone performs the process of event analysis, with reference to the structure shown in fig. 9 and the display control flow shown in fig. 14.

S401, under the conditions that the external folding screen mobile phone is in a folding state, the main screen is not locked and the screen is on, the registration service in the system service registers the target event monitor.

The target event monitor is used for monitoring the target event. The target event means that a user performs a preset operation on the secondary screen.

In this application, the system service may include a registration service and a gesture service, that is, the registration service and the gesture service are each a sub-service thread in the system service process. The registration service is used for registering a time monitor corresponding to any event so as to realize monitoring operation on the event. The gesture service is used for identifying gesture operations (such as touch operations) on the folding-out screen mobile phone.

In some embodiments, the registration service may obtain a specific screen folding state, a specific screen on-off state, a specific screen unlocking state, and the like of the out-folded screen mobile phone. Specifically, after the registration service obtains a specific screen folding state, whether the specific screen folding state is a folding state or not may be judged by comparison. After the registration service acquires the specific screen on-off state, whether the specific screen on-off state is the screen on-off state can be judged through comparison. After the registration service obtains the specific screen unlocking state, whether the specific screen unlocking state is the unlocking state or not, namely whether the specific screen unlocking state is the screen unlocking state or not can be judged through comparison.

In one possible implementation, the registration service may not register the target event listener when the out-folded mobile phone is in an unfolded state, or the home screen is in a locked state, or the home screen is in an off-screen state. Or under the condition that the out-folded screen mobile phone is in an unfolding state, or the main screen is in a screen locking state, or the main screen is in a screen extinguishing state, if the registration service has registered the target event monitor, the registration service can log off the registered target event monitor. The registration service may implement deregistration of registered target event listeners by calling a deregister listener function unregister device listner ().

In one possible implementation, the registration service may register the target event listener with the out-of-focus handset in a folded state, the home screen unlocked, and the bright screen. The above-described registration target event listener may be implemented by a registration device listener function registerDeviceListner (), for example.

In some embodiments, in the case that the out-folded screen mobile phone is in a folded state, the main screen is not locked, and the screen is on, if the registration service has registered the target event monitor, the registration will not be repeated, specifically, the registration service may determine by querying whether the monitor list in the registration service includes information of the target event monitor, and if the monitor list in the registration service includes information of the target event monitor, it indicates that the target event monitor has been registered, so the registration service does not need to register the target event monitor again. If the list of listeners in the registration service does not include information of the target event listener, it indicates that the target event listener is not registered, and thus the registration service may register the target event listener.

It can be understood that, in the above-mentioned screen folding state, screen on-off state and screen unlocking state, only if one state information is changed, the above-mentioned registration service is triggered to judge whether the screen meets the conditions of folding state, screen unlocking and screen brightening, so as to judge whether to register or cancel the above-mentioned target event monitor.

S402, a gesture service in the system service receives a target event monitor sent by a registration service.

Specifically, after the target event monitor is registered, the registration service may send the target event monitor to a gesture service in the system service, so that the gesture service may return the target event to the registration service after determining that the touch operation of the user on the secondary screen is the target event.

S403, an acceleration sensor in the out-folded screen mobile phone receives touch operation of a user on the auxiliary screen.

In the application, after the user touches the auxiliary screen of the external folding screen mobile phone, the acceleration sensor in the external folding screen mobile phone can receive the touch operation. The acceleration sensor is used for acquiring the motion condition of a finger or a finger joint of a user on the auxiliary screen, for example, sensing clicking operation acting on the auxiliary screen and the like.

S404, the gesture service receives touch operation sent by the acceleration sensor.

Specifically, after the acceleration sensor receives the touch operation, the acceleration sensor may send the touch operation to the gesture service, so that the gesture service determines whether the touch operation of the user on the secondary screen is a target event.

S405, the gesture service judges whether the input event corresponding to the touch operation is a target event.

Specifically, after the gesture service receives the touch operation, the gesture service may determine whether the input event corresponding to the touch operation is a target event, and if the input event corresponding to the touch operation is a target event, it indicates that the user wants to start the secondary screen service, so the gesture service may call the target event monitor and send the target event to the registration service. If the input event corresponding to the touch operation is not the target event, it is indicated that the user may touch the secondary screen by mistake or want to call other services, so the gesture service does not need to send the target event to the registration service.

In some embodiments, the gesture service may determine whether the input event corresponding to the touch operation is a target event through a preset algorithm, for example, the preset algorithm may be a back screen tapping (TapTap) algorithm or the like.

It is to be appreciated that different gesture operations (or touch operations) may correspond to different service applications. For example, a double-click operation for the home screen corresponds to a screenshot service application. For another example, an up-slide operation for the home screen corresponds to exiting the service application. For another example, a double-click operation for the secondary screen corresponds to a secondary screen service application.

S406, when the input event corresponding to the touch operation is a target event, the gesture service calls the target event monitor and sends the target event to the registration service.

In the application, if the input event corresponding to the touch operation is a target event, the gesture service may call the target event monitor through the device management service, so that after the method in the call target event monitor is executed, the target event may be returned to the registration service. The device management service (hwExtDeviceManage) may acquire an input event corresponding to the touch operation detected by the acceleration sensor.

It can be appreciated that if the input event corresponding to the touch operation is not a target event, the gesture service may not call the target event listener.

S407, the registration service controls the secondary screen service application to be started based on the target event.

In the application, after the registration service receives the target event sent by the gesture service, the registration service may control the secondary screen service application to be started according to the target event. The secondary screen service application is an application program provided by the embodiment of the application, so that the target two-dimensional code is displayed on the secondary screen.

S408, the secondary screen service application sends a query instruction to the intelligent center station.

Specifically, after the secondary screen service application is started, the secondary screen service application may send a query indication to the intelligent intermediate station. The query instruction is used for indicating the intelligent center station to determine target two-dimensional code information. The target two-dimensional code information can comprise an application name corresponding to the target two-dimensional code, the type of the target two-dimensional code and the like.

S409, under the condition that the intelligent middle station receives the inquiry instruction, combining the user behavior data to determine target two-dimensional code information.

In the application, after the intelligent middle station receives the inquiry instruction, the intelligent middle station can combine the user behavior data to determine the target two-dimensional code information.

S410, the intelligent center station sends the target two-dimensional code information to the auxiliary screen service application.

Specifically, after the intelligent center station determines the target two-dimensional code information, the intelligent center station can send the target two-dimensional code information to the auxiliary screen service application. The floating window may include at least one of an application name corresponding to the target two-dimensional code, an application icon corresponding to the target two-dimensional code, a type of the target two-dimensional code, and a display state of the target two-dimensional code. The display state can comprise a back screen bright code state and a bright code failure state, wherein the back screen bright code state is used for indicating that the back screen successfully displays the two-dimensional code, and the bright code failure state is used for indicating that the back screen fails to successfully display the two-dimensional code. In some embodiments, the floating window may further include a drop-down control, where the drop-down control is used to display information of the two-dimensional code to be switched, so that the user can select the two-dimensional code.

In some embodiments, in the case that the secondary screen service application receives the target two-dimensional code information, the secondary screen service application may present the target two-dimensional code on the secondary screen and the floating window on the primary screen. The following will describe in detail how the out-folded mobile phone displays the target two-dimensional code on the secondary screen by combining the structure shown in fig. 9 and the display control flow shown in fig. 15.

S501, the secondary screen service application judges whether the target process exits.

In the application, after the secondary screen service application receives the target two-dimensional code information, the secondary screen service application can judge whether the target process exits, and if the target process does not exit, the external folding screen mobile phone is in a normal scene. Therefore, the secondary screen service application can display the target two-dimensional code on the secondary screen, namely, can normally draw a window corresponding to the target two-dimensional code.

In some embodiments, if the target process has been exited, it is indicated that the out-folded mobile phone may be in an abnormal scene or the user does not want to display the target two-dimensional code, so in order to avoid waste of memory resources caused by drawing the target two-dimensional code, the secondary screen service application may not display the target two-dimensional code on the secondary screen.

S502, under the condition that the target process does not exit, the secondary screen service application sends a message for pulling up the target two-dimension code to the application activity management service by calling the application activity starting function.

The target two-dimensional code is the two-dimensional code displayed on the secondary screen by default or the two-dimensional code selected by the user to be displayed on the secondary screen. For example, the secondary screen service application may display the user interface of the target two-dimensional code by launching an application activity (activity).

The above-described message transmitted to the AMS may be carried through an intention (intent) parameter. The intent parameter specifies the activity to be initiated (simply referred to as the target activity), i.e., the intent parameter includes a data description of the target activity. The AMS may create a corresponding application activity record (activity record) by parsing this intent parameter before continuing the subsequent activity-starting process.

In addition, in the embodiment of the present application, the target two-dimensional code is required to be displayed on a secondary screen of the out-folded screen mobile phone. The message sent by the secondary screen service application to the AMS also carries identification information (for example, an application name or a preset unique number) of the sender, that is, the secondary screen service application. Accordingly, after the AMS receives the above-described message, it may determine whether it is a message transmitted by the secondary screen service application based on the identification information of the sender in the message. If yes, the display area related to the target activity is adjusted, and the display area of the target activity is set as a secondary screen. Therefore, when the window is created based on the target activity to display the target two-dimensional code, the display area of the window is a secondary screen.

S503, the activity management service sends a notification for starting the activity of the target application to the target application based on the message.

The target application activity is used for displaying the target two-dimensional code.

After the AMS creates an application activity record based on the received message, it may first determine whether an application process indicated by the application activity record (i.e., the target application process) exists. If the target application process does not exist, the AMS may start the target application process first and then send a notification to the target application to start the target activity. If the target application process exists, a notification for starting the target activity is directly sent to the target application.

S504, the target application starts the target application activity based on the notification.

After the target application receives the notification of the AMS, a corresponding application activity thread (activity thread) is created, and the target activity is started.

Illustratively, the application active thread may implement the initiation of the target activity by calling functions onCreate () and onResume ().

S505, the target application creates a view tree of the first window through the target application activity.

In the application, after the target application starts the target activity, the target application may create a view (view) tree of the first window through the target activity. The first window is used for displaying the target two-dimensional code. Illustratively, the first window displays a user interface of the target application, the user interface including the target two-dimensional code. For example, if the target two-dimensional code is a payment code of a certain application, the payment code interface of the application is displayed on the first window. For another example, if the target two-dimensional code is a riding code of a certain application, the riding code interface of the application is displayed on the first window. It is to be understood that this is by way of example only and is not limiting of the embodiments of the present application.

S506, the target application sends the view tree of the first window to the window management service.

Wherein the window management service (window manager service, WMS) is a sub-service thread in the system service process. The window management service can at least realize the functions of window management, window animation or assisting an input system to receive input events.

The above-described sending of the view tree of the first window to the window management service may be implemented by calling a setview () function, for example. For example, the setview () function may add the view tree of the first window to the window management service by calling the Addwindow () function. For another example, the setview () function may also layout the first window by calling a requestlayout () function.

S507, the window management service applies for the vertical synchronization signal of the secondary screen to the interface mapping service.

In this application, after the WMS receives the view tree sent by the target application, the WMS may apply for a vertical synchronization (Vsync) signal for secondary screen refresh to the interface mapping service. The VSync signal may synchronize the frame number per second (frames per second, FPS), i.e., the frame rate, with the refresh rate of the sub-screen in order to avoid "tearing" of the picture. That is, if the VSync signal is not present, when the frame data is rendered faster, the refresh of the sub-screen may not follow, and a certain frame is currently displayed, and another frame is triggered to be displayed on the screen, so that a phenomenon of "tearing" of the picture may occur.

Among these, the above interface mapping service (surfacefringer) is also a system service. The interface mapping service can assist and cooperate with WMS to realize window management.

S508, the interface mapping service returns a notification of the vertical synchronization signal to the target application.

Upon arrival of the next VSync signal, the interface mapping service returns a notification of the VSync signal to the target application.

And S509, the target application calls the rendering module to draw the first window in response to the vertical synchronous signal of the auxiliary screen.

In this application, after the target application receives the notification of the Vsync return signal, the target application may call the rendering module to draw the first window. For example, the target application may draw the first window by calling the ViewRootpl# performTeversals () function. Illustratively, the performTraversals () function may call a performdraw () function or the like to draw the first window.

And S510, the target application sends the drawn first window to the interface mapping service.

In the application, after the first window is drawn, the target application may send the first window to the interface mapping service.

S511, the interface mapping service synthesizes the content of the first window into a graph to obtain a first synthesized graph.

Specifically, after the interface mapping service receives the first window sent by the target application, the interface mapping service may perform graphics synthesis on the first window to obtain a first synthesized graphic. The first synthesized graph comprises the target two-dimensional code.

S512, the interface mapping service sends the first synthesized graph to the display management service.

The display manager service is also a system service, and can manage the life cycle of window display.

S513, the display management service displays the first synthesized graph on the secondary screen.

In S502, the display area of the target activity is set as the sub-screen, and the first window is a window of the target activity, so that the display management service may display the graphic synthesized by the first window on the sub-screen, and may display the target two-dimensional code on the sub-screen.

It can be understood that the floating window displayed on the main screen of the out-folded screen mobile phone and the target two-dimensional code displayed on the auxiliary screen are synchronously displayed, that is, the target two-dimensional code is correspondingly displayed on the auxiliary screen while the floating window is displayed on the main screen, so that in the process of drawing the first window by the target application, the target application can need to draw the floating window (or called a second window) on the main screen. The procedure of how the out-folded screen mobile phone displays the floating window on the main screen will be described in detail with reference to the structure shown in fig. 9 and the display control flow shown in fig. 16.

S601, the target application sends a notification for drawing a first window to the activity management service.

Specifically, after the target application receives the notification of the return vertical synchronization signal sent by the interface mapping service, the target application may send a notification of drawing the first window to the activity management service. Wherein the notification of drawing the first window is used to characterize that the first window is being drawn.

S602, the activity management service sends the notification for drawing the first window to the auxiliary screen service application.

Specifically, after the activity management service receives the notification of the first window sent by the target application, the activity management service may send the notification of drawing the first window to the secondary screen service application.

S603, the secondary screen service application sends a notification for drawing the second window to the target application.

In this application, after the secondary screen service application receives the notification of drawing the first window sent by the activity management service, the secondary screen service application may send a notification of drawing the second window to the target application. Wherein the notification of drawing the second window is used to indicate the drawing of the floating window.

S604, the target application creates a view tree of the second window.

Specifically, after the target application receives the notification sent by the secondary screen service application to draw the second window, the target application may create a view tree of the second window. The second window is used for displaying the floating window. The second window may illustratively display a user interface for any application in the out-turned screen handset, the user interface including the floating window. That is, the target application can display the floating window under the condition that the display content of the main screen is not affected, and the use experience of the user is improved. For example, referring again to interface (a) in fig. 3, the target application may display a hover window 302 over the electronic book being displayed by the home screen.

S605, the target application sends the view tree of the second window to the window management service.

The above-described sending of the view tree of the second window to the window management service may be implemented by calling a setview () function, for example. For example, the setview () function may add the view tree of the second window to the window management service by calling the Addwindow () function. For another example, the setview () function may also layout the second window by calling a requestlayout () function.

S606, the window management service applies for the vertical synchronization signal of the main screen to the interface mapping service.

In this application, after the WMS receives the view tree sent by the target application, the WMS may apply for a vertical synchronization (Vsync) signal refreshed by the main screen to the interface mapping service. The VSync signal may synchronize the frame number per second (frames per second, FPS), i.e., the frame rate, with the refresh rate of the main screen in order to avoid "tearing" of the picture. That is, if the VSync signal is not present, when the frame data is rendered faster, the refresh of the main screen may not be followed, a certain frame may be displayed currently, and another frame is triggered to be displayed on the screen, so that a phenomenon of "tearing" of the picture may occur. It will be appreciated that the refresh rate of the primary screen may be the same as that of the secondary screen described above, or may be different, and is not particularly limited.

S607, the interface mapping service returns a notification of the vertical synchronization signal to the target application.

And S608, the target application calls the rendering module to draw the second window in response to the vertical synchronous signal of the main screen.

In this application, after the target application receives the notification of the Vsync return signal, the target application may call the rendering module to draw the second window. For example, the target application may draw the second window by calling the ViewRootpl# performTeversals () function. Illustratively, the performTraversals () function may call a performdraw () function or the like to draw the second window.

S609, the target application sends the drawn second window to the interface mapping service.

In the application, after the second window is drawn, the target application may send the second window to the interface mapping service.

S610, the interface mapping service synthesizes the content of the second window into a graph to obtain a second synthesized graph.

Specifically, after the interface mapping service receives the second window sent by the target application, the interface mapping service may perform graphics synthesis on the second window to obtain a second synthesized graphic. Wherein the second composite graphic may include the floating window described above.

S611, the interface mapping service sends the second synthesized graph to the display management service.

S612, the display management service displays the second synthesized graph on the main screen.

It is understood that, since the second window is a window displaying a floating window, the display management service may display the second synthesized graphic based on the second window to the sub-screen, so that the second synthesized graphic may be displayed on the main screen.
