Before introducing the method provided by the embodiment of the application, an application scenario related to the embodiment of the application is first described.

With the rapid development of terminal technology, electronic devices such as mobile phones, tablet computers, smart watches, and the like are widely used. In order to meet the use requirement of users on large screens and to consider the volume of electronic equipment, electronic equipment with folding screens is produced. Especially, the electronic equipment carrying the outer folding screen not only enlarges the screen area of the electronic equipment and reduces the volume of the electronic equipment, but also can avoid crease when the screen is in a folding state compared with the inner folding screen, and prolongs the service life of the screen of the electronic equipment. Taking an external folding screen mobile phone as an example, as shown in fig. 1, a schematic diagram of the external folding screen mobile phone in an unfolded state is shown, where the external folding screen is divided into three screen areas 101, 102 and 103; when the folding-screen mobile phone is in an unfolded state, the three screen areas 101, 102 and 103 can be combined into one screen for displaying; when the folding mobile phone is in a folded state, in some application scenarios, the screen area 101 with larger area can be independently used as the main screen of the folding mobile phone, and the screen area 102 with smaller area can together form the back screen of the folding mobile phone with the screen area 102; in other applications, screen area 101 may together with screen area 103 form the main screen of the out-turned screen phone, and screen area 102 may be used alone as the back screen of the out-turned screen phone. It should be noted that, when the folding mobile phone is in a folded state, the screen area 101 and the screen area 102 may be in opposite positions, and the screen area 103 may be located between the screen area 101 and the screen area 103, and located at a side of the folding mobile phone and perpendicular to the screen area 101 and the screen area 102, respectively. Fig. 2 is a schematic diagram of a folding mobile phone in a folded state, where the positional relationship among the screen area 101, the screen area 102 and the screen area 103 can refer to fig. 2 when the folding mobile phone is in a folded state.

Currently, various types of applications may be installed or configured in an electronic device to meet different business requirements of a user, for example, the electronic device is a mobile phone, and the mobile phone may install an application for implementing social, work, entertainment, shopping, payment, and other functions. For the folding screen mobile phone, in order to enrich the use scene of the mobile phone, a payment two-dimensional code and the like can be displayed in the back screen so as to improve the convenience of use of a user. For example, for WeChat ^TM Payment device ^TM And the application program with the payment function is needed, if the user needs to open the payment two-dimensional code during payment, the user needs to click an icon corresponding to the application program through a main interface of the mobile phone to open the application program, and click a control corresponding to the payment two-dimensional code in the application program to display the payment two-dimensional code. Therefore, in order to simplify the process of opening the two-dimension code payment by the user, the micro-letter can be triggered to be displayed in the back screen interface through a specific instruction ^TM Payment device ^TM The payment two-dimensional code of the application program with the payment function is triggered by a specific gesture (such as using a finger joint to strike a plurality of places (such as 2 places)) so as to display the payment two-dimensional code in the back screen; or triggering the back screen bright code service when detecting the scanning operation of the external scanning equipment (such as a cashing code scanner) on the back screen so as to display the payment two-dimensional code in the back screen. However, if the back screen bright code service is triggered every time, the display service is restarted, a plurality of activity jumps are performed in the starting process, the starting speed is low, and in order to improve the user experience, the started back screen bright code service can be kept in a cache display task corresponding to the back screen, so that the starting efficiency of the back screen bright code service is improved.

However, when the back screen wakes up (such as a bright screen and an unlocked screen), the screen defaults to enter a process even if the back screen is not in a bright code scene, and resumeTopAnature is performed, so that in a non-back screen bright code scene, an interface corresponding to the bright code scene of the back screen is displayed in the back screen. And when the screen is lightened or the animation is executed in the process of exiting the interface, the back screen task interface is displayed.

Therefore, in order to solve the above problem of displaying the back screen light code task in the non-back screen light code service, the embodiments of the present application provide a display method, which can hide the buffer memory task corresponding to the current screen area when the buffer memory display task corresponding to the preset screen area is not required to be displayed, thereby avoiding the problem of indiscriminate display of the buffer memory display task in the application scenario where the buffer memory display task is not required to be displayed, so that the screen state or display content of the preset screen area is kept consistent with the actual use requirement of the user, and the use experience of the user is improved.

It should be noted that the above application scenarios are only exemplary, and the application scenario configuration of the display method provided in the embodiment of the present application is not limited, that is, the method may also be applied to other application scenarios where a cache task is required to be displayed on the back screen.

In addition, it should be noted that, the foregoing is described taking a mobile phone as an example, and in addition, the display method provided in the embodiment of the present application may also be applied to electronic devices such as a motion camera (go pro), a digital camera, a tablet computer, a desktop, a laptop, a handheld computer, a notebook, a vehicle-mounted device, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (personal digital assistant, PDA), an augmented reality (augmented reality, AR) \virtual reality (VR) device, a wearable device (e.g., a wearable smart bracelet, etc.), a smart home device (e.g., a smart refrigerator, a smart television, etc.), which is not limited in the embodiment of the present application.

The software system of the electronic device may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In the embodiment of the application, an Android (Android) system with a layered architecture is taken as an example, and a software system of an electronic device is illustrated.

Fig. 3 is a block diagram of a software system of an electronic device according to an embodiment of the present application. Referring to fig. 3, the layered architecture divides the software into several layers, each with a clear role and division of work. 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, an application framework layer, an Zhuoyun row (Android run time) and system layer, and a kernel layer, respectively. In addition, fig. 3 also shows the relationship between the hardware layers and the software system. As one example of the present application, the hardware layer includes a display screen for displaying various display tasks in the electronic device, such as displaying a two-dimensional code in a back screen, displaying wallpaper, displaying an incoming call, and so forth.

The application layer may include a series of application packages. As shown in fig. 3, the application package may include a back screen bright code application, which is used for implementing main functions such as display interaction of the two-dimensional code on the back screen, including start-up exit control, window display control, state synchronization, event transmission, and the like. The back screen bright code application can comprise a task management module, and the task management module can comprise applications such as mask display, task switching, recommended service list, capsule display, activity pull-up and the like. The application layer may also include a third party software development kit, such as a third party application (e.g. WeChat) that can provide two-dimensional code services such as payment of two-dimensional codes ^TM Payment device ^TM Etc.). Although not shown in the figure, the application layer may further include applications such as instant messaging, call, camera, gallery, map, navigation, WLAN, bluetooth, music, video, short message, etc.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions. As an example of the present application, as shown in fig. 3, the application framework layer may include at least a back screen bright code interface set, a window management service (window manager service, WMS), an intelligent engine, and an activity management service (activity manager servic e, AMS). The intelligent engine can comprise an intelligent perception module, when the back screen bright code service is started, the intelligent engine can display the recommended service functions in the recommended service list in the back screen preferentially according to the recommended service list in the application program layer, and when the recommended service list is empty, the service functions set by the user can be displayed in the back screen according to the setting of the user. For example, including WeChat in recommended services list ^TM When the corresponding payment function is triggered, the WeChat can be displayed in the back screen when the back screen bright code scene is triggered ^TM The corresponding payment two-dimensional code; if the recommended service list is empty, setting the user to display payment treasures in the back screen bright code scene ^TM The corresponding payment two-dimensional code can display the payment treasures in the back screen when the back screen bright code scene is triggered ^TM And the corresponding payment two-dimensional code.

The AMS module realizes embedded Activity starting and life cycle management, and the WMS module realizes embedded Task (Task) management, activity jump control in the Task, focus and visibility management of a back screen Task window scene, config update and compatibility management. The AMS and WMS modules provide a back screen Task window interface layer for system applications to use.

Android runtimes include core libraries and virtual machines. Android run time is responsible for scheduling and management of the Android system. The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android. The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules, such as: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc. The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications. Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as: MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The display method, apparatus, electronic device, storage medium, and computer program provided in the present application are described in detail below with reference to the accompanying drawings.

On the basis of the software architecture of the electronic device shown in fig. 3, the display method provided in the embodiment of the application is described next. Referring to fig. 4, fig. 4 is a schematic flow chart of a display method provided in an embodiment of the present application, which may be implemented by the electronic device shown in fig. 3, and the electronic device is implemented by interaction of the above modules, and the method may include some or all of the following:

Step 401, when a current trigger instruction for a screen of the electronic device is obtained, determining a current screen area corresponding to the current trigger instruction.

The current trigger instruction may include any one of the following instructions: the display device comprises a screen-brightening instruction, a screen unlocking instruction, a historical display task termination instruction and the preset instruction, wherein the historical display task refers to a display task which is being displayed in a current screen area before a current trigger instruction is acquired.

It should be noted that, the preset instruction may refer to an instruction that triggers the display of the cache display task in the preset screen area of the electronic device. For example, in a back screen bright code scene of the out-folded screen electronic device, the preset screen area may be a back screen, the preset instruction may be an instruction for triggering a back screen bright code service (for example, when the finger joint is used to strike the back screen, the back screen bright code is tapped), and the cache display task is a display task corresponding to the back screen bright code.

The current screen area may refer to a screen area where a current trigger instruction occurs in a screen of the electronic device, or may refer to a screen area where display content or a display state changes after the current trigger instruction occurs. It should be noted that, when the current trigger instruction is different, the corresponding current screen area may also be different.

In the embodiment of the present application, a back screen bright code service of an external folding screen electronic device is taken as an example, and a display method of the embodiment of the present application is described. The display method of the embodiment of the present application may also be triggered by other cached display tasks of the back screen, which will not be described in detail herein.

In this embodiment of the present application, when a back screen light code service of an out-folded screen electronic device is turned on, if the back screen light code service is already started, a buffer display task corresponding to the back screen light code service is buffered in a task stack, so as long as a display state of the back screen is changed (for example, from light screen to off screen, from off screen to light screen, display task switching, screen switching, etc.), a problem that an interface corresponding to the back screen light code service is displayed in the back screen will occur. Therefore, the triggering instruction of the screen of the electronic device can be monitored, when the triggering instruction of the screen is monitored, the current screen area corresponding to the current triggering instruction is determined, whether the current triggering instruction can cause the display state of the preset screen area (namely, the back screen in the back screen bright code scene) to change or not is judged through the subsequent steps, so that when the current triggering instruction can cause the interface corresponding to the cache display task to be displayed in the back screen, the cache display task is hidden in time, and therefore the interface corresponding to the cache display task is prevented from being displayed when the cache display task is not required to be displayed, and the use experience of a user is improved.

In one possible implementation manner of the embodiment of the present application, since the display state or the display content of the back screen may be changed by the screen-on instruction, the screen-unlocking instruction, the history display task termination instruction, and the preset instruction for triggering the back screen-on code service, when any one of the above instructions is monitored, it may be determined that the current trigger instruction is acquired, and the current screen area corresponding to the current trigger instruction is determined.

As a possible implementation manner, a screen wake-up instruction (such as clicking a screen) actively initiated by a user when the screen is off can trigger the screen of the electronic device to lighten; in some scenarios, when the electronic device receives a new message trigger message notification of an application, the electronic device is also triggered to light up. Thus, in embodiments of the present application, the on-screen instruction may include at least one of a screen wake instruction, a message notification instruction.

It should be noted that, the types of the bright screen instructions mentioned in the embodiments of the present application are only exemplary, and should not be construed as limiting the present application. In actual use, the type of the screen-lighting instruction is related to the actual function of the electronic device, and all the instructions capable of triggering the screen of the electronic device can be used as the screen-lighting instructions in the embodiment of the application, which is not limited in the embodiment of the application.

As an example, the screen wake-up instruction may be an instruction initiated actively by a user, such as clicking an arbitrary area of the electronic device, triggering a power key of the electronic device, or lifting the electronic device, which may trigger a screen of the electronic device. When the back screen is used for displaying wallpaper, if the back screen corresponds to the cache display task, the cache display task is displayed first and then the wallpaper is displayed, so that an interface corresponding to the back screen bright code task is displayed when a user triggers the bright screen but does not trigger the back screen bright code service, and the interface does not accord with the actual use requirement of the user, and therefore, the current screen area corresponding to the screen wake-up instruction can be determined when the screen wake-up instruction input by the user is acquired.

For example, assuming that the screen wake-up operation is a user clicking on the screen, if the screen wake-up logic of the electronic device wakes up the entire screen by clicking any screen area, the entire screen area of the electronic device may be determined as the current screen area; for example, as shown in fig. 1, if the user clicks on the screen area 101 or the screen area 102 when the screen of the electronic device is off, the entire screen areas 101, 102, and 103 may be determined as the current screen area. If the screen wake-up logic of the electronic device is that only the clicked screen area is waken up, the screen area clicked by the user can be determined as the current screen area; for example, as shown in the folding screen electronic device in fig. 1, when the user clicks the screen area 101 when the screen of the electronic device is off, the screen area 101 may be determined as the current screen area; alternatively, the user clicking on the screen region 102 may determine the screen region 102 as the current screen region when the screen of the electronic device is off.

It should be noted that the above examples are only exemplary and should not be construed as limiting the present application. In actual use, the instruction type included in the screen wake-up instruction and the determination mode of the current screen area corresponding to the screen wake-up instruction can be determined according to actual needs and specific application scenarios, which is not limited in the embodiment of the present application.

As an example, the screen wake-up instruction may also be an instruction, such as a message notification instruction, that may actively trigger a screen of the electronic device to light up. For example, the message notification instruction may include various application message notification instructions, such as a short message notification instruction, an instant messaging software new message notification instruction, an incoming call instruction, and so on. Taking an incoming call instruction as an example, assuming that the electronic device starts a back screen display incoming call function, an incoming call interface can be displayed on the back screen when the electronic device is in an incoming call, but if a buffer display task corresponding to the back screen exists, the buffer display task is displayed first and then the incoming call interface is displayed, which is inconsistent with the actual use requirement of a user. Therefore, when an arbitrary message notification instruction (e.g., an incoming call instruction) is acquired, the screen area where the message notification is to be displayed can be determined as the current screen area to which the message notification instruction corresponds.

For example, assuming that the message notification instruction is an incoming call instruction and the back screen turned on by the electronic device displays an incoming call function, the back screen may be determined as the current screen area when the incoming call instruction is acquired.

As a possible implementation manner, when the screen of the electronic device is in a folded state, if the screen of the electronic device is unlocked, the back screen displays the screen locking wallpaper after the electronic device acquires the screen unlocking instruction, and the screen is turned off after the main screen is successfully unlocked. However, if the back screen corresponds to the cache display task, the back screen also displays the cache display task first and then the screen is turned off, so that an interface corresponding to the back screen bright code task is also displayed when the user does not trigger the back screen bright code service and does not accord with the actual use requirement of the user, and therefore, the back screen area can be determined to be the current screen area when the screen unlocking instruction input by the user is acquired.

It should be noted that, as shown in fig. 1, if the main screen is the screen area 101 when the main screen is unlocked according to the actual service requirement, the screen area 102 and the screen area 103 may be determined to be the back screen together, that is, the screen area 102 and the screen area 103 are determined to be the current screen area; if the main screen is the screen area 101 and the screen area 103 according to the actual service requirement, the screen area 102 can be determined as the back screen, that is, the screen area 102 is determined as the current screen area.

As one possible implementation, the back screen should be off when the task that the back screen is displaying is terminated. For example, when a task being displayed by the back screen is switched to the home screen display, the back screen should be turned off. However, if the back screen corresponds to the cache display task, the back screen also displays the cache display task first and then the back screen is turned off, so that an interface corresponding to the back screen bright code task is displayed when the user does not trigger the back screen bright code service and does not accord with the actual use requirement of the user, and therefore, the back screen area can be determined as the current screen area when the history display task termination instruction is acquired.

As one example, the history display task termination instruction may be a screen switch instruction. For example, when the back screen and the rear camera of the out-folded screen electronic device are positioned on the same plane of the electronic device, if the user wants to self-shoot through the rear camera, the user can display a camera preview interface through the back screen so as to take a picture, namely, a back screen self-shooting scene; however, if the user wishes to switch the camera preview interface to the main screen for display in the back screen self-timer scene, the user may click on the screen switch instruction in the camera preview interface to switch to the main screen, and display the animation corresponding to the switch screen in the switching process. However, as shown in fig. 1, since in the back screen self-timer scene, in order to make the camera preview interface more convenient for the user to view, only the screen area 102 may be determined as the back screen, that is, the camera preview interface is displayed in the screen area 102, the screen area 101 and the screen area 103 together constitute the main screen; when the camera preview interface is switched from the back screen to the home screen for display, only the screen area 101 may be determined as the home screen, that is, the camera preview interface may be displayed only in the screen area 101, which may cause the back screen to be switched from the screen area 102 to the screen area composed of the screen area 102 and the screen area 103. If the back screen corresponds to the buffer display task, the buffer display task is partially displayed in the screen area 103 (the rest of the buffer display task is displayed in the screen area 102 but is covered by the screen switching animation), so that an interface corresponding to the back screen bright code task is also displayed when the user does not trigger the back screen bright code service, and does not accord with the actual use requirement of the user, and therefore, the back screen area can be determined as the current screen area when the screen switching instruction is acquired.

As a possible implementation manner, the preset instruction may refer to an instruction that triggers the cache display task to be displayed in a preset screen area. For example, in a back screen bright code scene, the preset instruction may be an instruction for triggering a cache display task corresponding to the back screen bright code service to be displayed on the back screen, for example, using a finger joint to strike two places in a back screen area.

As a possible implementation manner, when the current trigger instruction is the preset instruction, the cache display task may be displayed in the preset screen area, that is, the subsequent steps in the embodiments of the present application are not executed any more.

It should be noted that if the current trigger instruction is a preset instruction, it may be determined that the buffer display task corresponding to the preset screen area needs to be displayed currently, and then the buffer display task corresponding to the preset screen area may be directly displayed in the preset screen area.

For example, in a back screen bright code scene, assuming that the preset instruction is that the finger joints strike under the back screen, and the preset screen area is the back screen, when the user operation of the finger joints striking under the back screen is detected, the back screen can be awakened, and a resumeTopAN_SNatity method is executed to display a cache display task corresponding to the back screen bright code service in the back screen.

Step 402, hiding the buffer display task corresponding to the preset screen region when the current screen region includes the preset screen region and the current trigger instruction is not the preset instruction.

In the embodiment of the application, taking the back screen bright code service as an example, presetting a screen area as a back screen, if the current trigger instruction is not the preset instruction, determining that the current trigger instruction is not the back screen bright code scene, and displaying a cache display task corresponding to the back screen bright code service is not needed; if the current screen area is determined to be the preset screen area (namely the back screen), the display state or the display content of the current back screen can be determined to be changed, so that the cache display task corresponding to the back screen bright code is displayed in the back screen; therefore, the buffer memory display task corresponding to the preset screen area, namely the buffer memory display task corresponding to the back screen bright code service, can be hidden, so that the buffer memory display task corresponding to the back screen bright code service cannot be displayed in the back screen in the process of changing the display state or the display content of the back screen.

Further, since the system performs the unlocking process when the screen is on or unlocked, and performs the resumetopactionproperty method and the ensureactionproperty method after the screen status is marked as awake, the buffer display task is displayed in the screen. Therefore, when the current trigger instruction is a bright screen instruction or a screen unlocking instruction, the resumeTopAactigraphy method and the resumeActiveVisible method corresponding to the preset screen area can be prevented from being executed in the unlocking process, so that the cache display task is prevented from being displayed in a scene which does not need to be displayed. In one possible implementation manner of the embodiment of the present application, the current trigger instruction is a screen-on instruction or a screen-unlocking instruction; accordingly, the step 402 may include:

when the current trigger instruction is not a preset instruction, the screen type is a preset screen type, the current screen area is a preset screen area, and the screen state is an awake state, hiding the cache display task corresponding to the preset screen area.

The preset screen type can be determined according to actual needs and specific application scenes, which is not limited in the embodiment of the present application. For example, when the display method of the embodiment of the present application is applied to a back screen bright code scene, the preset screen type may be an out-folded screen.

Fig. 5 is a schematic flow chart of an unlocking process of a screen of an electronic device according to an embodiment of the present application. After the screen locking service acquires an unlocking instruction of a user, executing a keyguard GoingAway method through an active task management service (ActivityTaskManagerService) to enter an unlocking screen flow; then, a forallDisplays method is executed through a root window container (RootWindowContainer) to traverse all screen areas in the screen of the electronic equipment; then, a keyguard GoingAway method is executed through a keyguard controller, and an update keyguard sleep token method is executed so as to update the screen state of the currently traversed screen area into an awake state; further executing an applysleepcokens method to update the screen state of the currently traversed screen area to an awake state; and finally, executing a resumeTopAactigyInnerLocked method and an ensureActiviteseVicable method to display the cache display task corresponding to the screen area in the currently traversed screen area.

It can be seen that, in the above-mentioned native flow, after the bright screen instruction or the screen unlocking instruction is acquired, the resumetopactigyInnerLocked method and the ensureActiviteeVicable method are automatically executed to display the cache display task in the corresponding screen area. Therefore, in this embodiment of the present application, taking the back screen bright code service as an example, if the current trigger instruction is a bright screen instruction or a screen unlocking instruction, and it is determined that the current trigger instruction is not a preset instruction, the screen type corresponding to the screen of the electronic device is a preset screen type (such as an external folding screen), the current screen area is a preset screen area (back screen) and the screen state is a wake-up state, that is, it is determined that the current is a non-back screen bright code scene, the screen type is the external folding screen, and the back screen is currently updated to be the wake-up state, then the buffer display task corresponding to the preset screen area (back screen) can be hidden, that is, the buffer display task corresponding to the back screen bright code service is hidden, so as to prevent the display of bright screen scenes or screen unlocking scenes such as in incoming call display, and the back screen bright code is displayed.

As a possible implementation manner, when the current trigger instruction is a bright screen instruction or a screen unlocking instruction, the cache display task corresponding to the preset screen area may be hidden by the following manner:

As an example, as shown in fig. 5, when the screen is on or unlocked, when the screen is traversed to the preset screen area, after the appysleeptokens method is executed to update the screen state of the preset screen area to the awake state, the traversing process of the preset screen area can be completed, and the next screen area is continuously traversed, that is, the resumptopative insnerloned method and the ensureactive visual method are not executed, so as to prevent the buffer display task corresponding to the preset screen area from being displayed in the preset screen area.

The following is a code for hiding the cache display task corresponding to the back screen in the above manner:

if(HwFoldScreenState.isOutFoldDevice()&&display.getDisplayId()＝＝

DisplayEx.SUB_BUILTIN_DISPLAY&&！displayShouldSleep){continue；

}

wherein, the hwfoldstate.iseutfoldservice () is used for indicating whether the screen type is an external folding screen, when the screen type of the electronic device is an external folding screen, the value of the hwfoldstate.iseutfoldservice () is 1, otherwise, the value of the hwfoldstate.iseutfoldservice () is 0; the DISPLAY, getdisplayid () = displayid () = displayix, sub_brightness_display is used to indicate whether the current screen area is a back screen, when the current screen area is a back screen, the value of displayid () = displayid, sub_brightness_display is 1, otherwise the value of displayid () = displayid, sub_brightness_display is 0; the displaysheldsleep represents a screen state of the current screen region, and if the screen state of the current screen region is a screen-off state, the displaysheldsleep has a value of 1, and if the screen state of the current screen region is an awake state, the displaysheldsleep has a value of 0. Therefore, according to the codes, when the screen type corresponding to the screen of the electronic device is an outer folding screen, the current traversed screen area is a back screen, and the screen state of the current screen area is an awake state in the non-back screen bright code scene, the resumeTopatyInnerLocked method and the ensureActiveVicable method are not executed, and the next screen area is continuously traversed, so that the cache display task is prevented from being displayed in the non-back screen bright code scene.

Furthermore, since the unlocking process is not executed when the history display task is terminated (such as screen switch, hang-up, incoming call termination, wallpaper display termination, etc.), the cache display task corresponding to the preset screen area can be forcedly hidden, so that the cache display task can be prevented from being displayed when the display is not needed, and the usability is further improved. In one possible implementation manner of the embodiment of the present application, the current trigger instruction is a history display task termination instruction; accordingly, the step 402 may include:

As a possible implementation manner, taking the history display task termination instruction as an example of a screen switching instruction in the back screen self-timer scene, when the camera preview is switched from the back screen to the main screen display, as described above, the back screen area will change, so that during the screen switching process, the buffer display task corresponding to the back screen bright code service will be partially displayed in the newly added back screen area (such as the screen area 103 in fig. 1). In this scenario, the cache display Task may be forced to be hidden by the isForceHidden method in the Task (Task). That is, if it is determined that the screen type corresponding to the screen of the electronic device is a preset screen type (such as an out-folded screen), the current screen area is a preset screen area (a back screen), and the stack corresponding to the buffer display task is not empty (i.e., there is a buffer display task corresponding to the preset screen area currently), and the current trigger instruction is not a preset instruction (i.e., it is not a back screen bright code scene currently), the buffer display task corresponding to the preset screen area, that is, the buffer display task corresponding to the back screen bright code service is hidden, so as to prevent the display of the back screen bright code in the task termination scene such as screen switching.

As a possible implementation manner, when the current trigger instruction is a history display task termination instruction, the cache display task corresponding to the preset screen area may be hidden by the following manner:

and executing a method for forcedly hiding the cache display task.

As an example, when it is determined that the screen type corresponding to the screen of the sub device is a preset screen type (such as an out-turned screen), the current screen area is a preset screen area (back screen), and the stack corresponding to the buffer display Task is not empty (i.e., there is currently a buffer display Task corresponding to the preset screen area), and the current trigger instruction is not a preset instruction (i.e., not a back screen bright code scene), an isForceHidden method in the Task may be executed to forcedly hide the buffer display Task corresponding to the preset screen area.

if(！HwFoldScreenState.isOutFoldDevice()||currentTask＝＝null

||currentTask.getDisplayId()！＝DisplayEx.SUB_BUILTIN_DISPLAY){

return false；

}

return HwFoldScreenManager.getCurrentCoordinationTypeForOuter()！＝

HwFoldScreenManager.CoordinationTypeEnum.COORDINATION_TYPE_QUICK_SHOW_COD E；

wherein, the hwfoldstate.iseutfoldservice () is used for indicating whether the screen type is an external folding screen, when the screen type of the electronic device is an external folding screen, the value of the hwfoldstate.iseutfoldservice () is 1, otherwise, the value of the hwfoldstate.iseutfoldservice () is 0; the currenttask= =null is used for indicating whether the stack corresponding to the buffer display task is empty, if yes, the value of currenttask= null is 1, otherwise, the value of currenttask= null is 0; currenttask. Getdisplayid () Σ! =displayex. Sub_BUILTIN_DISPLAY is used to determine if the current screen area is a back screen, if the current screen area is not a back screen, currentTask getdisplayid () Σ! =

The value of displayix. Sub_BUILTIN_DISPLAY is 1, otherwise, currentTask. Getdisplayid () ]! =

The value of displayex. Sub_BUILTIN_DISPLAY is 0;

HwFoldScreenManager.getCurrentCoordinationTypeForOuter()！＝

HwFoldScreen manager, coordinationTypeEnum, COORDINATION_TYPE_QUICK_SHOW_COD E is used for indicating whether the scene is currently a back screen bright code scene, if not, then

HwFoldScreenManager.getCurrentCoordinationTypeForOuter()！＝

HwFoldScreen manager COORDINATION TYPE Enum COORDINATION TYPE QUICK SHOW COD E has a value of 1, otherwise HwFoldScreen manager GetCurrentCoordinationTypeForOuter ()! =

The value of HwFoldScreen manager.CoordinationTypeEnum.COORDINATION_TYPE_QUICK_SHOW_COD E is 0.

That is, through the above codes, if it is determined that the screen type is not an out-folded screen, or the stack corresponding to the buffer display task is empty, or the current screen area is not a back screen, neither the isForceHidden method is executed, that is, the buffer display task corresponding to the back screen bright code service is not hidden; if the screen type is determined to be an out-folded screen, a stack corresponding to the cache display task is not empty, the current screen area is a back screen, and the current screen area is not a back screen bright code scene, executing an isforceHidden method to forcedly hide the cache display task corresponding to the back screen bright code service.

Step 403, controlling the display state of the preset screen area according to the current trigger instruction.

In the embodiment of the application, if the scene of the corresponding cache display task is not required to be displayed in the preset screen area, after the cache display task corresponding to the preset screen area is hidden, the display state of the preset screen area can be controlled normally according to the current trigger instruction.

As a possible implementation manner, when the current trigger instruction is a screen unlocking instruction or a history display task termination instruction, the preset screen area can be controlled to be turned off.

It should be noted that, taking the back screen bright code service as an example, if the current trigger instruction is a screen unlocking instruction, after unlocking is completed, the back screen needs to enter a screen-off state, so that after the corresponding cache display task of the back screen, the back screen can be controlled to be turned off; if the current trigger instruction is a history display task termination instruction and the back screen is not needed to be displayed by other display tasks, the back screen can enter a screen-off state, so that the back screen can be controlled to be turned off.

As a possible implementation manner, when the current trigger instruction is a bright screen instruction, displaying a current display task corresponding to the current trigger instruction in a preset screen area.

It should be noted that, taking the back screen bright code service as an example, as mentioned above, when the back screen is bright, there is a corresponding display task, for example, when the user triggers the bright screen, there is a wallpaper display task; for another example, when the incoming call instruction is acquired, a display task for displaying the incoming call interface exists. Therefore, when the current trigger instruction is a bright screen instruction, a corresponding current display task can be displayed in the back screen according to the current trigger instruction. For example, when the current trigger instruction is an incoming call instruction, an incoming call interface may be displayed in the back screen.

According to the display method, when the current trigger instruction of the screen of the electronic device is obtained, the current screen area corresponding to the current trigger instruction is determined, when the current screen area comprises the preset screen area and the current trigger instruction is not the preset instruction, the cache display task corresponding to the preset screen area is hidden, and then the display state of the preset screen area is controlled according to the current trigger instruction. Therefore, when the preset screen area is triggered, and when the cache display task corresponding to the preset screen area is not required to be displayed, the cache task corresponding to the current screen area is hidden, so that the problem of indiscriminate cache display task display in an application scene without cache display task display is avoided, the screen state or display content of the preset screen area is consistent with the actual use requirement of a user, and the use experience of the user is improved.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.

Therefore, when the preset screen area is triggered, and when the cache display task corresponding to the preset screen area is not required to be displayed, the cache task corresponding to the current screen area is hidden, so that the problem of indiscriminate cache display task display in an application scene without cache display task display is avoided, the screen state or display content of the preset screen area is consistent with the actual use requirement of a user, and the use experience of the user is improved.
