Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

First, an interface of an application program in the embodiment of the present application will be described.

The interface of the application program in the embodiment of the application program is a medium interface for interaction and information exchange between the application program and a user, and the conversion between the internal form of the information and the form acceptable by the user is realized. A common presentation form of an Interface of an application program is a Graphical User Interface (GUI), which refers to a User Interface related to computer operation and displayed in a graphical manner. The interface of the application program may be composed of visual interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, and the like.

The interface of the application program allows a user to select an icon or a menu option in the interface by using an input device such as a mouse and the like so as to open a new interface. For example, as shown in fig. 1, taking the step-by-step menu option opening by the user as an example, the user opens one application program 1, enters an initial interface of the application program 1, can click a first-level menu 1 on the initial interface, enter an interface corresponding to the first-level menu 1, open a second-level menu 12 on the interface corresponding to the first-level menu 1, enter an interface corresponding to the second-level menu 12, and continue to open, for example, a third-level menu 123 on the interface corresponding to the second-level menu 12, and then an interface corresponding to the third-level menu 123, and so on.

In the existing implementation scheme, if a user wants to return to a certain interface which is opened before from a currently opened interface in an application program, the user needs to press a back key to implement the method, the more the hierarchy difference between the two interfaces is, the more times the back key needs to be pressed is, the complex operation is realized, and the user experience is influenced by the misoperation caused by the fact that the back key is pressed more easily.

Therefore, the embodiment of the application provides an interface switching method and device and electronic equipment, which can conveniently and quickly switch interfaces in application programs or between application programs, reduce misoperation of users, and improve user experience.

It should be noted that the application scope of the present application is not limited to the above mobile terminal using the android system, and the present application may be applied to an electronic device using the android system or another system, such as an IOS system. The electronic equipment can comprise mobile terminals (mobile phones), smart screens, unmanned aerial vehicles, Intelligent Internet vehicles (ICV for short), Intelligent (automobile) vehicles (smart/Intelligent car) or Vehicle-mounted equipment and the like.

The following describes an interface switching method according to an embodiment of the present application.

Fig. 2A is a flowchart of an embodiment of an interface switching method according to the present application, and as shown in fig. 2A, the method may include:

step 201: detecting interface switching operation of a user, and acquiring interface identifications of at least two interfaces corresponding to at least one target application program; the interface comprises an interface opened by a target application program; the target application is an opened application.

The interface switching operation may be directed to switching an interface within an application program, or may be directed to switching an interface between different application programs.

Referring to fig. 1, the interface opened by the user in the application 1, such as the initial interface, the interface corresponding to the first-level menu 1, the interface corresponding to the second-level menu 12, and the like, becomes an opened interface after being opened by the user. However, the application may close the opened interface based on a rule, and the embodiment of the application is not limited thereto.

Wherein, for the interface switching operation:

in one possible implementation, the interface switching operation may be a specific gesture made by the user on the screen, such as a three-finger pinch-and-slide, a two-finger merge-and-slide, a continuous click, and so on.

In another possible implementation manner, the interface switching operation may be to press a predetermined physical key once or multiple times continuously, or to press a predetermined physical key continuously for a predetermined time length. The specific pressing times of the continuous multiple pressing is not limited in the application, and the preset time length is not limited in the application.

The interface identifier of the interface is information for showing interface features, for example, the interface identifier of the interface may be a complete interface, that is, includes all interface elements of the interface; or, the interface identifier of the interface may also be a simplified interface, that is, the interface identifier includes interface middle interface element; alternatively, the interface identifier of the interface may be an interface screenshot of the interface. For example, referring to fig. 2B, assuming that the user clicks the icon of the application 1, the initial interface of the application 1 displayed on the screen of the electronic device is as shown in the left diagram of fig. 2B, and then the left diagram is the complete interface of the initial interface, the initial interface includes 4 first-level menu option buttons, and the interface including only 2 first-level menu option buttons in the right diagram of fig. 2B is the simplified interface of the initial interface; and the screenshot of the initial interface is the interface screenshot of the initial interface.

Step 202: and displaying the acquired interface identifications of the at least two interfaces in a first preset area.

The first preset area may be a part or all of the area on the screen, and the specific implementation may be set autonomously in the actual application. For example, referring to fig. 2C, the portion filled with oblique lines is a first preset region, a certain proportion of the upper region of the screen may be used as the first preset region, or a certain proportion of the lower region of the screen may be used as the first preset region, or a certain proportion of the middle region of the screen may be used as the first preset region. The specific value of the ratio can be set independently in practical application as long as the purpose of displaying the interface identifier can be achieved.

Step 203: and displaying an interface corresponding to the target interface identification on a screen according to the operation of selecting the target interface identification from the interface identifications displayed in the first preset area by the user.

If the interface identifier obtained in step 201 is a complete interface, displaying a target interface according to the target interface identifier in this step; if the interface identifier obtained in step 201 is a simplified interface or an interface screenshot, in this step, when the target interface corresponding to the target interface identifier is displayed on the screen, an interface corresponding to the target interface identifier needs to be obtained first, and then the obtained interface is displayed on the screen.

In a possible implementation manner, when the interface corresponding to the target interface identifier is displayed on the screen, information input by the user when the interface is opened last time can be displayed on the screen, so that the user does not need to input information on the interface again, and the user experience is improved.

In the method shown in fig. 2A, an interface switching operation of a user is detected, interface identifiers of at least two interfaces corresponding to at least one target application program are obtained, the interfaces include interfaces opened by the target application program, the target application program is an opened application program, the obtained interface identifiers of the at least two interfaces are displayed in a first preset area, and an interface corresponding to the target interface identifier is displayed on a screen according to an operation of selecting the target interface identifier from the interface identifiers displayed in the first preset area by the user, so that the user can conveniently and quickly switch the interfaces in the application program or between the application programs, and does not need to press a back key for multiple times to switch the interfaces, thereby reducing misoperation of the user and improving user experience.

In the embodiment of the present application shown in fig. 3A, taking an interface switch in an application as an example, referring to fig. 3A, the method may include:

step 301: and detecting interface switching operation of a user aiming at the application program to which the current display interface belongs, and acquiring interface identifications of at least two interfaces of the application program to which the current display interface belongs.

The current display interface refers to an interface which is being displayed on a screen of the electronic equipment when the interface switching operation is executed. Taking fig. 1 as an example, suppose that a user clicks an icon of an application 1 to open the application 1, and an initial interface of the application 1 is displayed on a screen of the electronic device, at this time, the initial interface of the application 1 is a current display interface, and the application 1 is an application to which the current display interface belongs.

The user does not limit how to implement the embodiment of the present application specifically for the interface switching operation of the application program to which the current display interface belongs. For example:

in one possible implementation manner, the interface switching operation of the user for the application program to which the current display interface belongs may be a specific gesture, such as three-finger pinch-and-slide, two-finger pinch-and-slide, continuous clicking and the like, performed by the user on the screen.

In another possible implementation manner, the interface switching operation of the user for the application to which the current display interface belongs may be to press a certain preset entity key once or continuously for multiple times, or to continuously press a certain preset entity key for a preset time length. The specific pressing times of the continuous multiple pressing is not limited in the embodiment of the present application, and the preset time length is not limited in the embodiment of the present application.

The obtaining of the interface identifiers of at least two interfaces of the application program to which the current display interface belongs may include:

the method comprises the steps of obtaining information of at least two interfaces of an application program to which a current display interface belongs, and obtaining interface identifications of the at least two interfaces according to the information of the at least two interfaces. The information of the interface may include: and (4) interface ID.

The obtaining of the information of the at least two interfaces of the application program to which the current display interface belongs may include:

acquiring information of a current display interface and information of at least one interface close to the hierarchy of the current display interface; or acquiring information of at least two interfaces close to the hierarchy of the currently displayed interface.

In practical application, the information of the interface can be obtained by calling ActivityStack, and the interface screenshot of the interface can be obtained by the capture L player function of the SurfaceControl.

Step 302: and displaying the acquired interface identification in a first preset area.

In a possible implementation manner, the acquired interface identifiers may be displayed in a first preset area in a splicing manner according to a hierarchical sequence of the interface corresponding to the interface identifier, where the hierarchical sequence may be from high to low, or from low to high, and the like.

When the number of the acquired interface identifiers is small, the acquired interface identifiers can be directly arranged and spliced from left to right in sequence according to a hierarchical order, for example, assuming that 3 interface identifiers are acquired, the hierarchical order is interface 1, interface 2 and interface 3 from low to high, as shown in fig. 3B, the 3 interface identifiers can be spliced and displayed in a first preset area according to the order of the hierarchy of the interface from low to high;

when the number of the acquired interface identifiers is large, the interface identifiers may be divided into 2 rows or more in a hierarchical order for splicing display, for example, assuming that 6 interface identifiers are acquired, the hierarchical order of the corresponding interfaces is from interface 1 to interface 6 from low to high, as shown in fig. 3C, the displayed interface identifiers may be divided into 2 rows for splicing display. Referring to fig. 3D, when the number of the acquired interface identifiers exceeds the maximum number of the interface identifier splicing display, paging may be performed, one page is displayed in the first preset area (shown by a solid line in fig. 3D), and the other pages are not displayed temporarily (shown by a dotted line in fig. 3D), so that the user is supported to replace the display page through sliding and other operations. Optionally, the display page of the initial first preset area may include: the interface identifier of the current display interface is used for a user to refer to the interface identifier of the current display interface, so that the user can more easily understand the hierarchical relationship between the interface identifiers in the display page, and the specific display position of the interface identifier of the current display interface in the page to which the interface identifier belongs is not limited in the embodiment of the application.

In another possible implementation manner, the acquired interface identifiers may be displayed in the first preset area in a manner of overlapping according to a hierarchical order of the interfaces. For example, assuming that 6 interface identifiers are obtained, the interfaces 1 to 6 are sequentially arranged from the bottom to the top in the hierarchical order, as shown in the left diagram in fig. 3E, the obtained interface identifiers are displayed in an overlapping manner in the order from the top to the bottom, so that the user is supported to replace the interface identifier displayed at the top layer through operations such as sliding, and as shown in the right diagram in fig. 3E, the interface identifier displayed at the top layer is replaced from the interface identifier 6 to the interface identifier 4 under the operation of the user. Optionally, the interface identifier of the first preset area, which is initially located at the uppermost layer, may be an interface identifier of the currently displayed interface, so that the user may refer to the interface identifier of the currently displayed interface, so that the user may more easily understand the hierarchical relationship between the interface identifiers.

In yet another possible implementation manner, the acquired interface identifier may be displayed in the first preset area in a paging manner according to a hierarchical order of the interface. For example, each page may exhibit an interface identifier, similar to that shown in FIG. 3D; alternatively, the paging display may be combined with the aforementioned splicing display to perform paging display, as shown in fig. 3D.

In yet another possible implementation manner, the first preset area may be divided into a first sub-area and a second sub-area, the obtained interface identifiers are displayed in the first sub-area in a splicing manner, or in an overlapping manner, or in a paging manner according to a hierarchical order of the interface, and the selected interface identifier in the first sub-area is displayed in the second sub-area. The size between the first subregion and the second subregion is not limited in the embodiments of the present application. For example, assuming that 6 interface identifiers are obtained, the interfaces 1 to 6 are sequentially arranged from low to high in the hierarchical order of the corresponding interfaces, as shown in fig. 3F, the interface identifiers are displayed in the first sub-area in a stacked manner according to the hierarchical order, and when the user selects the interface identifier 4, the selected interface identifier 4 is displayed in the second sub-area. In another possible implementation manner, instead of displaying the interface identifier 4 in the second sub-region, the interface corresponding to the selected interface identifier 4 may be displayed in the second sub-region.

In yet another possible implementation manner, the acquired interface identifiers may be displayed in the first preset area according to the hierarchical order of the interfaces according to the sliding offset of the interface switching operation on the screen. The amount of slip offset generally refers to: in the user performing the interface switching operation on the screen, the center point of the contact surface of the finger of the user and the screen is displaced on the screen. The implementation mode can be combined with other possible implementation modes so as to replace the interface identifier displayed in the first preset area according to the operation of the user. Specifically, for example, it is determined in the direction of the sliding offset whether to change from the currently displayed interface identifier to an interface identifier at a higher level or to an interface identifier at a lower level; determining the currently displayed interface identifier and the display proportion of the first-level interface identifier adjacent to the interface identifier according to the proportion of the sliding offset in the transverse width of the screen, and determining the target interface identifier selected by the user in the interface identifiers displayed in the first preset area when the interface switching operation of the user is finished according to the proportion of the sliding offset in the transverse width of the screen. For example:

assuming that 6 interface identifiers are obtained, the interface identifiers 1 to 6 are sequentially arranged from low to high in the hierarchical order, the current display interface identifier (i.e., the current display interface in step 301) is the interface identifier 6, if the direction of the sliding offset is from left to right, the interface is replaced in the direction of the interface identifier 5, and if the direction of the sliding offset is from right to left, the interface identifier is replaced in the direction of the interface identifier 6 at the next stage, because the next stage of interface identifier of the interface identifier 6 is not available in the present example, the interface replacement operation of the user may not be responded; taking the direction of the sliding offset from left to right as an example, the ratio x of the lateral offset of the interface switching operation in the lateral width of the screen can be calculated, as shown in fig. 3G, the display ratio of the interface identifier 6 in the first preset area is set to 1-x, and the display ratio of the interface identifier 5 in the first preset area is set to x.

When the user finishes sliding from left to right, that is, the interface switching operation is finished, the target interface identifier selected by the user from the interface identifiers displayed in the first preset area may be determined according to the ratio x, specifically, the interface identifier with a large display ratio in the first preset area may be used as the target interface identifier, for example, when x is greater than 0.5, the interface identifier 5 is the target interface identifier, and when x is less than or equal to 0.5, the interface identifier 6 is the target interface identifier.

Step 303: and displaying a target interface corresponding to the target interface identifier on a screen according to the operation of selecting the target interface identifier from the interface identifiers displayed in the first preset area by the user.

Optionally, as shown in fig. 4A, step 303 may further include:

step 401: and when detecting that the user opens a new interface in the target interface, closing other interfaces higher than the target interface level except the new interface in the interface.

The hierarchy of interfaces in the present application is illustrated. Referring to fig. 1, the level of the initial interface of the application 1 is 1, the level of the interface of the first-level menu 1 opened on the initial interface is 2, the level of the interface of the second-level menu 12 opened on the interface of the first-level menu 1 is 3, and the larger the value of the level is, the higher the level is.

This step is illustrated by way of example:

assume levels of opened interfaces are 1, 2, 3, 4, 5, 6; and if the level of the target interface is 4, the level of the new interface is 5, and then interfaces with levels 5 and 6 in the interfaces which are opened except the new interface are closed.

It should be noted that, in practical applications, the management of the opened interface in the application program may be performed in a task stack manner. When the interface management of the task stack is performed, the opened interfaces are placed in the task stack according to the hierarchical sequence, and when the current display interface is switched to the target interface in step 203, in a possible task stack management manner, the position of the interface higher than the target interface in the task stack can be moved to the bottommost layer, the positions of other opened interfaces in the task stack can be moved up, and further, when a new interface is opened in step 301, the interface higher than the target interface in the hierarchy can be deleted from the task stack. For example, the following steps are carried out: as shown in fig. 3B, if the interfaces in the task stack are a to E from low to high according to the hierarchy, and the target interface is C, when step 203 is executed, the interfaces D and E higher than the hierarchy of the interface C in the application program move from the upper layer to the bottommost layer of the task stack, and the positions of the interfaces a to C move up sequentially, and a new interface F is opened from the interface C in step 301, the interface D and the interface E are deleted from the task stack, and the interface F is added to the topmost layer of the task stack.

In the task stack, the interface moved to the lowest layer may be marked specifically, and the effect of the special mark on the task stack is as follows: the user is prevented from returning from the initial interface or the interface at the lower level to the interface at the highest level moved to the lowest level of the task stack when performing the return operation. Taking the second task stack in fig. 4B as an example, when the user performs the return operation, the interface C in the task stack may return to the interface B, and the interface B may return to the interface a, and by a special mark, the user may be prevented from returning to the interface E from the interface a when performing the return operation, thereby preventing the application program from generating an error. In addition, if the interface switching operation of the user is detected after step 203, that is, the processing returns to step 201, it can be ensured that the opened interfaces acquired from the task stack are still interfaces arranged in the normal hierarchical order by the special mark. For example, continuing the above example, the target interface in step 203 is interface C, at this time, the structure of the task stack is as shown in the second task stack in fig. 4B, at this time, if the interface switching operation of the user is detected, step 201 will be returned to, and the interface that has been opened from the task stack may be acquired according to the special mark of the interface as follows: A. b, C, D, E are provided.

For example, from the interface switching perspective, the effect of the special mark on the interface and the user is to identify that the interface is in the invisible to-be-destroyed state. Referring to fig. 4C, it is assumed that an interface switching operation is detected when the application displays the interface C, and then the interface is switched to the interface B at the previous stage, at this time, the interface C may be specially marked to identify that the interface C is in an invisible to-be-destroyed state, and the interface C is still an opened interface, and a user performs the interface switching operation under the interface B, and may still switch from the interface B to the interface C, but if the user opens the interface D in the interface B, the interface C is closed, that is, deleted from the task stack.

Through the addition of step 401, it can be ensured that only the new interface and the interface with a lower hierarchy than the new interface are already opened interfaces, and the interface which is opened by the user and has the same hierarchy as or a higher hierarchy than the new interface is closed, so that the data amount required to be processed when the application executes the interface switching method of the application, that is, the data amount required to be processed when the electronic device executes the interface switching method of the application, is reduced.

In the embodiment of the present application shown in fig. 5A, taking an interface switch between applications as an example, referring to fig. 5A, the method may include:

step 501: and detecting interface switching operation of a user, and acquiring an application program identifier of the opened application program.

Wherein the application identification comprises at least one of: an application name, an application icon, or an interface screenshot of an application.

Step 502: and displaying the acquired application program identification in a second preset area.

The setting of the second preset area may refer to the related description of the setting of the first preset area, and the method for displaying the application program identifier in the second preset area may refer to the method for displaying the interface identifier in the first preset area, which is not described herein again.

Optionally, in step 501, information about the number of opened interfaces in the opened application program may also be obtained; correspondingly, in step 502, the acquired quantity information and the application program identifier are correspondingly displayed in the second preset area.

When the application program identifier and the quantity information are correspondingly displayed, the quantity information may be displayed in a preset area of the application program identifier, for example, a special area such as an upper right corner, a lower right corner, an upper left corner, a lower left corner, a central point, or any non-special area on the application program identifier, which is not limited in the embodiment of the present application.

Step 503: and detecting that the user selects the target application program operation from the application program identifiers displayed in the second preset area, and acquiring the interface identifiers of at least two interfaces corresponding to the target application program.

The specific implementation of selecting the target application program operation is not limited in the embodiment of the present application, and may be, for example, an application program identifier displayed by clicking the second preset area.

The number of target application programs that can be selected by the user in the second preset area is not limited in the embodiment of the present application.
