Description

Wallpaper deleting method and electronic equipment

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a method for deleting wallpaper and an electronic device.

Background

With the development of electronic devices, the use of electronic devices is becoming more and more abundant. In order to enhance the user's experience with the electronic device, the user may be setting and changing a lock screen wallpaper or desktop wallpaper of the electronic device. The user may also delete the disliked wallpaper. However, a wallpaper deletion failure may occur due to a system upgrade or system change of the electronic device 100.

Disclosure of Invention

The application provides a method for deleting wallpaper and electronic equipment, which can ensure that the wallpaper is successfully deleted and that the electronic equipment can display a wallpaper deleting interface after the wallpaper is deleted.

In a first aspect, the present application provides a method for deleting wallpaper, the method comprising: the electronic equipment displays a first user interface of a first application, wherein the first user interface comprises a first wallpaper picture and a first wallpaper deleting option, and the first wallpaper deleting option is used for deleting the first wallpaper picture; the electronic equipment receives a first operation of a user aiming at a first wallpaper deleting option; in response to the first operation, the electronic device references an address of a second wallpaper picture as a first variable referenced by a main thread of the first application; the electronic equipment creates a second variable and a sub-thread of the first application, and assigns the participation of the first variable to the second variable, wherein the participation of the second variable is the address of the second wallpaper picture, and the sub-thread of the first application refers to the second variable; the electronic equipment deletes the first wallpaper picture through the sub-thread of the first application; the electronic device displays a second user interface of the first application, wherein the second user interface does not comprise the first wallpaper picture, and the second user interface comprises the second wallpaper picture.

The second wallpaper picture may be a new wallpaper picture automatically set by the electronic device after the user deletes the first wallpaper picture.

Optionally, a first identifier may be displayed on the first wallpaper picture, where the first identifier is used to indicate that the first wallpaper picture is a screen-locking wallpaper and/or a desktop wallpaper that is currently being used by the electronic device.

The electronic device can execute the operation of deleting the wallpaper through the sub-thread of the first application so as to lighten the load of the main thread of the first application, and the efficiency of deleting the wallpaper and resetting the wallpaper can be improved.

Before the electronic device performs the operation of deleting the wallpaper through the sub-thread of the first application, the electronic device needs to create a second variable. The sub-thread of the first application needs to refer to the second variable and take the address of the second wallpaper picture as the reference of the second variable.

In the case where the reference of the second variable referenced by the child thread of the first application is not null, the child thread of the first application may successfully delete the first wallpaper picture. Because the sub-thread of the first application refers to the second variable instead of the first variable, when the electronic device deletes the first wallpaper picture currently used by the electronic device, the electronic device executes the operations of destroying the wallpaper interface and restarting the wallpaper interface, and when the electronic device executes the operations of destroying the wallpaper interface and restarting the wallpaper interface, the electronic device sets the participation of the first variable referred to by the main thread to be empty. The reference of the second variable which is cited by the sub-thread is not set to be empty, so that the sub-thread can be ensured to continuously execute the operation of deleting the first wallpaper picture, and the wallpaper picture is ensured to be deleted successfully.

With reference to the first aspect, in one possible implementation manner, before the electronic device receives a first operation of a user on the first wallpaper option, the method further includes: the electronic equipment takes the first wallpaper picture as lock screen wallpaper and/or desktop wallpaper of the electronic equipment; after the electronic device receives the first operation of the user for the first wallpaper deleting option, the method further comprises: the electronic device takes the second wallpaper picture as lock screen wallpaper and/or desktop wallpaper of the electronic device.

Thus, after the user actively deletes the desktop wallpaper and/or the lock screen wallpaper currently used by the electronic device, the electronic device can automatically re-use the new desktop wallpaper and/or the lock screen wallpaper for the electronic device.

Optionally, a second identifier may be displayed on the second wallpaper picture, where the second identifier is used to indicate that the second wallpaper picture is a screen-locking wallpaper and/or a desktop wallpaper that is currently being used by the electronic device.

With reference to the first aspect, in one possible implementation manner, the electronic device uses the second wallpaper picture as a lock screen wallpaper and/or a desktop wallpaper of the electronic device, and specifically includes: and the electronic equipment sets the second wallpaper picture as the screen locking wallpaper and/or the desktop wallpaper of the electronic equipment through the sub-thread of the first application.

Specifically, the electronic device obtains an address of a second wallpaper picture through a second variable of the sub-thread application of the first application, and sets the second wallpaper picture as screen locking wallpaper and/or desktop wallpaper of the electronic device based on the address of the second wallpaper picture.

Thus, after the user actively deletes the desktop wallpaper and/or the lock screen wallpaper currently used by the electronic device, the electronic device may set the second wallpaper picture to the lock screen wallpaper and/or the desktop wallpaper of the electronic device through the sub-thread of the first application.

With reference to the first aspect, in one possible implementation manner, after the electronic device receives the first operation of the user for the first wallpaper deleting option, before the electronic device displays the second user interface of the first application, the method further includes: the electronic equipment clears the parameter of the first variable; the electronic device stops displaying the first user interface.

When the electronic device deletes the desktop wallpaper and/or the lock screen wallpaper which are currently used by the user, the electronic device empties the entry of the first variable which is referenced by the main thread, and stops displaying the first user interface. The electronic device then redraws and displays the second user interface.

With reference to the first aspect, in a possible implementation manner, the second user interface further includes a second wallpaper deleting option, where the second wallpaper option is used to delete the second wallpaper picture.

Thus, after the user actively deletes the first wallpaper picture, the electronic device automatically sets a new wallpaper picture (i.e., the second wallpaper picture) for the electronic device, and continues to display a wallpaper deletion interface, wherein the wallpaper deletion interface comprises wallpaper options, so that the user can delete a plurality of wallpaper pictures continuously.

With reference to the first aspect, in one possible implementation manner, after the electronic device receives a first operation of a user on a first wallpaper option, the method further includes: the electronic equipment generates a first cache file, wherein the first cache file comprises a label of a deletion interface of wallpaper.

With reference to the first aspect, in one possible implementation manner, in response to deleting the first wallpaper picture, the electronic device displays a second user interface of the first application, and specifically includes, in response to deleting the first wallpaper picture, the electronic device acquires a first cache file; the electronic equipment acquires a tag of a deleting interface of the wallpaper from the first cache file; and in response to acquiring the label of the deleting interface of the wallpaper, the electronic equipment displays a second user interface of an application.

Therefore, before the electronic equipment stops displaying the first user interface, the electronic equipment can record the label of the wallpaper deleting interface through the first cache file, so that when the electronic equipment redisplays the user interface of the wallpaper application, the electronic equipment can display the wallpaper deleting interface, namely a second user interface, based on the label of the wallpaper deleting interface recorded in the first cache file, and the second user interface can comprise a wallpaper deleting option.

With reference to the first aspect, in one possible implementation manner, the electronic device includes a wallpaper database, where the wallpaper database includes an address of the first wallpaper picture; after the electronic device receives the first operation of the user for the first wallpaper deleting option, the method further comprises: and the electronic equipment writes the address of the second wallpaper picture into the wallpaper database through the sub-thread of the first application.

After the electronic device resets the wallpaper picture, the electronic device needs to write the address of the second wallpaper picture into the wallpaper database, so that the address of the second wallpaper picture can be recorded in the wallpaper database, and the second wallpaper picture can be obtained based on the address of the second wallpaper picture recorded in the wallpaper database.

With reference to the first aspect, in a possible implementation manner, the electronic device writes the address of the second wallpaper picture into the wallpaper database through the sub-thread of the first application, and specifically includes; the electronic equipment obtains the address of a second wallpaper picture through a second variable referenced by the sub-thread of the first application; and the electronic equipment writes the address of the second wallpaper picture into the wallpaper database through the sub-thread of the first application.

In this way, the electronic device may write the address of the second wallpaper picture to the wallpaper database via the sub-thread of the first application.

With reference to the first aspect, in one possible implementation manner, after the electronic device receives a first operation of a user on a first wallpaper option, the method further includes: the electronic device deletes the address of the first wallpaper picture in the wallpaper database through the sub-thread of the first application.

After the electronic device resets the wallpaper picture, the electronic device also needs to delete the address of the first wallpaper picture in the wallpaper database.

Optionally, the electronic device may delete the address of the first wallpaper picture in the wallpaper database through a sub-thread of the first application.

With reference to the first aspect, in one possible implementation manner, the first user interface includes a second wallpaper picture.

With reference to the first aspect, in one possible implementation manner, the first user interface does not include the second wallpaper picture.

The new wallpaper picture set by the electronic device may be displayed in the first user interface, or the new wallpaper picture set by the electronic device may not be displayed in the first user interface.

In the embodiment of the invention, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated.

Fig. 2 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present invention.

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, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications for cameras, gallery, calendar, phone calls, maps, navigation, WLAN, bluetooth, music, video, short messages, 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 shown in FIG. 2, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The telephony manager is used to provide the communication functions of the electronic device 100. Such as the management of call status (including on, hung-up, etc.).

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library 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. For example: 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.

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 workflow of the electronic device 100 software and hardware is illustrated below in connection with capturing a photo scene.

When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, time stamp of touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, taking a control corresponding to the click operation as an example of a control of a camera application icon, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera driver by calling a kernel layer, and captures a still image or video by the camera 193.

The user may set the lock wallpaper and the desktop wallpaper of the electronic device 100. In some embodiments, a wallpaper deletion failure may occur due to a system change of the electronic device 100.

Fig. 3A-3G show UI diagrams of wallpaper deletion failure on electronic device 100.

Illustratively, as shown in FIG. 3A, the electronic device 100 displays a main interface. The main interface may include: status bar, tray with common application icons, and other application icons. Wherein the status bar may include a time indicator, a battery status indicator, one or more signal strength indicators of a wireless high-fidelity (wireless fidelity, wi-Fi) signal, one or more signal strength indicators of a mobile communication signal (also may be referred to as a cellular signal).

Other application icons may be, for example: an icon of a clock, an icon of a calendar, an icon of a gallery, an icon of a memo, an icon of a video, and a set icon. The icon of any one of the applications may be used to cause the electronic device 100 to launch the application to which the icon corresponds in response to an operation (e.g., a click operation) by the user. Wherein the set icon may be used to initiate an application setting. The electronic device 100 may modify the setting items of the electronic device 100 through the setting application.

As shown in fig. 3A, the electronic device 100 receives an input operation (e.g., a click) of an icon of a setup application by a user, and in response to the input operation by the user, the electronic device 100 displays a user interface 310 as shown in fig. 3B. A number of settings are shown in the user interface 310, such as a flight mode setting (current flight mode has been turned off), a Wi-Fi setting (current Wi-Fi has been turned off), a bluetooth setting (current bluetooth function has been turned off), a personal hotspot setting, a mobile network setting, a do-not-disturb mode setting, a display and brightness setting, a Hua-Chen account setting, a wallpaper setting, and so forth.

As shown in fig. 3B, the electronic device 100 receives an input operation (e.g., a click) of the wallpaper setting item by the user, and in response to the input operation by the user, the electronic device 100 displays a user interface 320 as shown in fig. 3C.

The user interface 320 may be a setup interface of wallpaper.

As shown in fig. 3C, a plurality of wallpaper pictures are shown in user interface 320 along with interface identification 3203 and current wallpaper identification 3202. The plurality of wallpaper pictures include a wallpaper picture 3201 and a wallpaper picture 3304, wherein a current wallpaper identifier 3202 is displayed on the wallpaper picture 3201, and the current wallpaper identifier 3202 is used for indicating that wallpaper currently used by the electronic device 100 is the wallpaper picture 3201. Interface identifier 3203 is used to indicate that user interface 320 is a wallpaper setting interface, and a user may change wallpaper, delete wallpaper, add wallpaper, etc. in user interface 320.

When the user needs to delete wallpaper, the user may operate a delete interface into the wallpaper in user interface 320.

For example, as shown in fig. 3C, the electronic device 100 may receive an input operation (e.g., a long press operation) by a user with respect to the wallpaper picture 3201, and in response to the input operation by the user, the electronic device 100 may display the user interface 330 shown in fig. 3D.

The user interface 330 may be a delete interface of wallpaper.

As shown in fig. 3D, a plurality of wallpaper pictures are shown in user interface 330 along with interface identification 3301 and current wallpaper identification 3202. The plurality of wallpaper pictures include a wallpaper picture 3201 and a wallpaper picture 3304, wherein a current wallpaper identifier 3202 is displayed on the wallpaper picture 3201, and the current wallpaper identifier 3202 is used for indicating that wallpaper currently used by the electronic device 100 is the wallpaper picture 3201. Interface identification 3203 is used to indicate that user interface 330 is a delete interface for wallpaper. The user may delete wallpaper in user interface 320. Also included in the user interface 330 is a delete option for deleting wallpaper. As shown in fig. 3D, each wallpaper picture has a delete option, and the delete option on each wallpaper picture is used to delete the corresponding wallpaper picture. For example, a delete option 3302 is displayed on the wallpaper picture 3201, and the delete option 3302 is used to delete the wallpaper picture 3201. A delete option 3305 is displayed on the wallpaper picture 3304, and the delete option 3305 is used to delete the wallpaper picture 3304.

Alternatively, in some embodiments, the electronic device 100 may only receive user operations to delete custom wallpaper or operator wallpaper, etc., and may not delete system wallpaper. The customized wallpaper can be a wallpaper picture made of pictures selected by a user from a gallery, and the operator wallpaper can be a wallpaper picture downloaded by the user from a server. The system wallpaper may be a wallpaper picture with a threshold within the device at the factory of the electronic device 100.

For example, the electronic device 100 may receive an input operation (e.g., a long press operation) by a user with respect to the wallpaper picture 3201, and in response to the input operation by the user, the electronic device 100 may display the user interface 340 shown in fig. 3E. User interface 340 is similar to user interface 330, except that wallpaper picture 3303 in user interface 340 does not include delete option 3302, thereby indicating that wallpaper picture 3303 may be a system wallpaper, and that the user cannot delete wallpaper picture 3303.

After the electronic device 100 displays the user interface 330 shown in fig. 3D, the electronic device 100 may receive a user operation to delete one or more wallpaper pictures.

In some implementations, the electronic device 100 may receive a user operation to delete a wallpaper picture currently used by the electronic device 100. After the electronic device 100 deletes the wallpaper picture currently used by the electronic device 100, the electronic device 100 may automatically set a new wallpaper picture for the electronic device 100.

For example, as shown in fig. 3F, the electronic device 100 may receive an input operation (e.g., a single click) by a user for the delete option 3302 in the user interface 330, and in response to the input operation by the user, the electronic device 100 may display the user interface 350 shown in fig. 3G.

The user interface 350 may be a setup interface for wallpaper.

As shown in fig. 3G, a plurality of wallpaper pictures are shown in user interface 350 along with interface identification 3503 and current wallpaper identification 3502. The plurality of wallpaper pictures include a wallpaper picture 3501, a wallpaper picture 3201, a wallpaper picture 3304, and the like, wherein a current wallpaper identifier 3502 is displayed on the wallpaper picture 3501, and the current wallpaper identifier 3502 is used for indicating that wallpaper currently used by the electronic device 100 is the wallpaper picture 3501. Interface identification 3503 is used to indicate that user interface 350 is a delete interface for wallpaper.

As can be seen from fig. 3G, after the user performs the operation of deleting the wallpaper picture 3201, the wallpaper picture 3201 is further included in the user interface 350, that is, a case where the wallpaper picture deletion fails occurs. After the user performs the deletion of the wallpaper picture 3201, the user interface 350 is a wallpaper setting interface, and is not a wallpaper deletion interface. If the user needs to continuously delete a plurality of wallpaper pictures, the user needs to press the wallpaper pictures for a long time again to enter a wallpaper deleting interface, and the user operation is complicated.

Alternatively, after the user performs deleting the wallpaper picture 3201, not only the wallpaper picture 3501 is used as the wallpaper picture currently used by the electronic device 100, but also other wallpaper pictures displayed in the user interface 330 can be replaced by wallpaper pictures currently used by the electronic device 100, which is not limited in the present application.

Based on the above-described failure of wallpaper deletion and the schematic diagram of the setting interface that can only display wallpaper after the user performs the operation of deleting the wallpaper picture, the reason why the above-described failure of wallpaper deletion and the setting interface that can only display wallpaper after the user performs the operation of deleting the wallpaper picture will be explained next.

After the electronic device 100 receives the user operation to enter the wallpaper setting interface, the main thread of the wallpaper application will run. When the electronic device 100 receives a user operation to perform an operation of deleting a wallpaper picture in the wallpaper application, the electronic device 100 creates a sub-thread of the wallpaper application, and the sub-thread performs a task of deleting the wallpaper picture.

Currently, when the operation of deleting the wallpaper picture is performed, the system CONFIG (for example, config_asset_path=0x80000000) will change, and the electronic device 100 will call the wallpaper frame interface to reset the wallpaper picture, and when the wallpaper frame interface resets the wallpaper picture, the electronic device 100 performs two operations, which may include a wallpaper setting interface destruction operation and a wallpaper setting interface re-pull operation.

After the electronic device 100 performs the wallpaper setting interface re-pulling operation, the current wallpaper deleting interface is closed, and the wallpaper setting interface is re-entered, for example, the wallpaper setting interface similar to the user interface 320 is re-displayed according to the method shown in fig. 3A-3C. Without directly entering a wallpaper deletion interface like user interface 320 shown in fig. 3D. Resulting in the electronic device 100 not displaying a wallpaper deletion interface like the user interface 320 after the user performs the operation of deleting the wallpaper picture.

When the electronic device 100 receives a user operation to delete a wallpaper picture, as shown in fig. 4A, the electronic device 100 refers to an mdesetdefaultinfo variable in a stack, and the entry of the mdesetdefaultinfo variable is the address of the wallpaper picture currently used by the electronic device 100, and the wallpaper picture currently used by the electronic device 100 may be stored in the stack. For example, the entry of the mdelesetdefaultinfo variable may be the address of wallpaper picture 3501 shown in fig. 3G.

Meanwhile, when the electronic device 100 receives a user operation to delete the wallpaper picture, the electronic device 100 creates a sub-thread, and the sub-thread performs operations such as deleting the wallpaper picture and updating the database. As shown in FIG. 4B, the child thread will also reference the mDelSetDefaultInfo variable. When the electronic device 100 performs the wallpaper setting interface re-pull operation, the system invokes an onstop method that clears the entry of the mdeletsetdefaultinfo variable referenced by the main thread to clear the memory space. The child thread also refers to the mdeletsetdefaultinfo variable to perform operations such as deleting wallpaper pictures and updating databases. Since the entry of the mdeletsetdefaultinfo variable referenced by the main thread is empty, the entry of the mdeletsetdefaultinfo variable referenced by the sub-thread is also empty, and in the case where the entry of the mdeletsetdefaultinfo variable referenced by the sub-thread is empty, the sub-thread cannot update the database. The child thread cannot delete the wallpaper picture, namely the problem of wallpaper deletion failure occurs.

In order to solve the above problems, the present application provides a method for deleting wallpaper, which can ensure that wallpaper is successfully deleted, and simultaneously ensure that after a user performs a wallpaper picture deleting operation, the electronic device 100 can continuously display a wallpaper deleting interface, so that the user can continuously delete a plurality of wallpaper pictures, and the operation of the user is saved.

The application provides a wallpaper deleting method and electronic equipment. The method comprises the following steps: the electronic equipment displays a first user interface of a first application, wherein the first user interface comprises a first wallpaper picture and a first wallpaper deleting option, and the first wallpaper deleting option is used for deleting the first wallpaper picture; the electronic equipment receives a first operation of a user aiming at a first wallpaper deleting option; the electronic device takes the address of the second wallpaper picture as a reference of a first variable referenced by a main thread of the first application; responding to the first operation, the electronic equipment creates a second variable, takes the address of the second wallpaper picture as the reference of the second variable, and the sub-thread of the first application refers to the second variable; the electronic equipment deletes the first wallpaper picture through the sub-thread of the first application; in response to deleting the first wallpaper picture, the electronic device displays a second user interface of the first application, the second user interface including no first wallpaper picture.

First, an effect diagram after executing the wallpaper deleting method provided by the application is introduced.

Fig. 5A-5B illustrate U-diagrams of electronic device 100 after wallpaper is successfully deleted.

For example, as shown in fig. 5A, the electronic device 100 may receive an input operation (e.g., a single click) by a user for the delete option 3302 in the user interface 330, and in response to the input operation by the user, the electronic device 100 may display the user interface 510 shown in fig. 5B.

User interface 510 may be a delete interface for wallpaper.

As shown in fig. 5B, a plurality of wallpaper pictures are shown in user interface 510 along with interface identifier 3301 and current wallpaper identifier 5101. The plurality of wallpaper pictures include a wallpaper picture 3501, a wallpaper picture 3304, and the like, wherein the wallpaper picture 3501 is displayed with a current wallpaper identifier 5101, and the current wallpaper identifier 5101 is used for indicating that wallpaper currently used by the electronic device 100 is the wallpaper picture 3501. Interface identification 3301 is used to indicate that user interface 510 is a delete interface for wallpaper.

A delete option 5102 is displayed on the wallpaper picture 3501, and the delete option 5102 is used to indicate that the user interface 510 is a delete interface for wallpaper.

As can be seen in fig. 5B, the electronic device 100 has deleted the wallpaper picture 3201. Also, after the user performs the operation of deleting the wallpaper picture 3201, the electronic device 100 further displays a wallpaper deletion interface, for example, a deletion option is included on the wallpaper picture in the wallpaper deletion interface, and the deletion option is used for deleting the wallpaper picture by the user.

Next, description will be given of how the electronic device 100 successfully deletes the wallpaper and continues to display the wallpaper deletion interface after deleting the wallpaper.

Fig. 6 is a schematic diagram of a method for deleting wallpaper according to an embodiment of the present application.

As shown in fig. 6, the electronic device 100 includes an interface display module, a main thread, a system framework, and sub threads.

S601, the electronic device 100 displays a wallpaper deleting interface.

Illustratively, the delete interface of wallpaper may be user interface 330 shown in FIG. 3D.

S602, the electronic device 100 receives a user operation to delete the first wallpaper picture.

The wallpaper deleting interface comprises a first wallpaper picture.

For example, the first wallpaper picture may be the wallpaper picture 3201 shown in fig. 3D, the wallpaper picture 3201 being a wallpaper picture currently being used by the electronic device 100.

S603, in response to the operation of deleting the first wallpaper picture, the electronic device 100 assigns the mdelesetdefaultinfo variable referenced by the main thread as the address of the second wallpaper picture.

In response to the operation of deleting the first wallpaper picture, the electronic device 100 assigns the mdeletsetdefaultinfo variable referenced by the main thread as the address of the second wallpaper picture.

The address of the second wallpaper picture may be an address of the wallpaper picture 3201. That is, the second wallpaper picture is the same as the first wallpaper picture, and the first wallpaper picture deleted by the user is not the wallpaper picture currently being used by the electronic device 100.

S604, the electronic device 100 creates a DelSetDefaultInfo variable, and assigns the DelSetDefaultInfo variable as an address of the second wallpaper picture.

As shown in fig. 7A, in response to an operation to delete the first wallpaper picture, the electronic device 100 creates a DelSetDefaultInfo variable, and assigns the DelSetDefaultInfo variable to an address of the second wallpaper picture (e.g., an address of the wallpaper picture 3501). The value of the mdelesetdefaultinfo variable and the value of the deltadeltadeltadeltadeltadeltadeltadeltas are both addresses of the second wallpaper picture (e.g., wallpaper picture 3501).

Because after the user performs the wallpaper deleting operation, the electronic device 100 performs two operations of destroying the wallpaper deleting interface and re-pulling the wallpaper setting interface. During execution of these two operations by the electronic device 100, the electronic device 100 clears the value of the mdeletsetdefaultinfo variable referenced by the main thread of the electronic device 100 to free up memory space.

After the electronic device 100 clears the value of the mdeletsetdefaultinfo variable referenced by the main thread of the electronic device 100, based on the foregoing description, a problem may occur in that the wallpaper deletion fails and only the setting interface of the wallpaper can be displayed after the user performs the operation of deleting the wallpaper picture. To avoid this, the electronic device 100 would additionally create a DelSetDefaultInfo variable, assign the DelSetDefaultInfo variable to the address of the second wallpaper picture (e.g., the address of wallpaper picture 3501). I.e., the value of the DelSetDefaultInfo variable is the same as the value of the mDelSetDefaultInfo variable.

Thus, during the two operations performed by the electronic device 100, the electronic device 100 clears the value of the mdesetdefaultinfo variable referenced by the main thread of the electronic device 100, but the value of the DelSetDefaultInfo variable is not cleared, and the value of the DelSetDefaultInfo variable can be transferred to the sub-thread, so that the problems that wallpaper deletion fails and a setting interface only capable of displaying wallpaper after the user performs the wallpaper picture deleting operation are avoided.

S605, in response to the operation of deleting the first wallpaper picture, the electronic device 100 creates a child thread that references the deltasetdefaultinfo variable.

In response to the operation to delete the first wallpaper picture, the electronic device 100 creates a sub-thread, which may be a sub-thread of the first application. The sub-thread is used for executing the operation of deleting the first wallpaper picture and refreshing the database. Because the main thread also needs to execute other task matters, the operation of deleting the first wallpaper picture and refreshing the database is executed by the sub-thread of the first application, so that the burden of the main thread can be reduced, and the efficiency of deleting the wallpaper picture is improved.

As shown in fig. 7A, in response to the operation of deleting the first wallpaper picture, the electronic device 100 creates a child thread that references the deltasetdefaultinfo variable. The value of the DelSetDefaultInfo variable is the address of the second wallpaper picture and the value of the DelSetDefaultInfo variable is used to point to the second wallpaper picture.

S606, the electronic device 100 deletes the first wallpaper picture through the sub-thread.

The sub-thread refers to a DelSetDefaultInfo variable, the value of the DelSetDefaultInfo variable is the address of the second wallpaper picture, and the sub-thread can delete the first wallpaper picture under the condition that the value of the DelSetDefaultInfo variable is not null so as to realize successful deletion of the first wallpaper picture.

S607, the electronic device 100 generates a first cache file, where the first cache file includes a tag of a deletion interface of the wallpaper.

In response to the operation of deleting the first wallpaper picture, the electronic device 100 performs two operations of destroying the wallpaper deletion interface and restarting the wallpaper setting interface. After the electronic device 100 performs these two operations, the electronic device 100 may stay at a setup interface of wallpaper, such as the user interface 350 shown in fig. 3G. If the user needs to continuously delete a plurality of wallpaper pictures, the user needs to operate the wallpaper deletion interface again, and the user operation is complicated.

After the electronic device responds to the operation of deleting the first wallpaper picture, in order to enable the electronic device 100 to stay on the wallpaper deleting interface, the electronic device 100 can generate a first cache file in response to the operation of deleting the first wallpaper picture, wherein the first cache file comprises a label of the wallpaper deleting interface.

Alternatively, the electronic device 100 may call the SharePreferences method to generate and store the first cache file.

Optionally, the first cache file may include a key-value key pair. The value of the key may be is_deleted_cut_ WALLPAPER, and the value of the value may be true. The electronic device 100 may obtain a corresponding value according to the key, and further take a label of the deletion interface of the wallpaper.

S608, the electronic device 100 invokes the wallpaper frame interface to reset the wallpaper.

In response to the operation of deleting the first wallpaper picture, the electronic device 100 may call the wallpaper frame interface, reset the wallpaper by the wallpaper frame interface, and perform a restarting operation on the wallpaper interface by the wallpaper frame interface, so that the electronic device 100 may display the interface after deleting the first wallpaper picture.

S609, the electronic device 100 updates the database based on the DelSetDefaultInfo variable referenced by the child thread.

The electronic device 100 may update the database based on the DelSetDefaultInfo variable referenced by the child thread.

The electronic device 100 may obtain the address of the second wallpaper picture based on the DelSetDefaultInfo variable referenced by the sub-thread, and write the address of the second wallpaper picture into the database through the sub-thread, so that the address of the second wallpaper picture may be recorded in the database, and subsequently the second wallpaper picture may be obtained based on the address of the second wallpaper picture recorded in the database.

In one possible implementation, after the electronic device resets the wallpaper picture, the electronic device also deletes the address of the first wallpaper picture in the database.

Optionally, the electronic device may delete the address of the first wallpaper picture in the database through a sub-thread of the first application.

S610, the electronic device 100 calls the wallpaper frame interface to execute a restarting operation on the wallpaper interface.

The electronic device 100 invokes the wallpaper frame interface to perform a restarting operation on the wallpaper interface, that is, the wallpaper frame interface performs the restarting operation on the wallpaper interface, so that the electronic device 100 may display the interface after deleting the first wallpaper picture.

S611, the electronic device 100 executes the wallpaper interface destruction stage lifecycle management method.

The electronic device 100 executes the wallpaper interface destruction stage lifecycle management method, that is, in response to the operation of deleting the first wallpaper picture, executes the destruction operation of the wallpaper deletion interface and the restarting operation of the wallpaper setting interface, so that the electronic device 100 can display the interface after deleting the first wallpaper picture.

S612, the electronic device 100 sets the value of mdeletdefaultinfo variable referenced by the main thread to null.

Optionally, the electronic device 100 may call the onstop method, and execute the destruction operation of the wallpaper deletion interface and the restarting operation of the wallpaper setting interface through the onstop method, so that the electronic device 100 may display the interface after deleting the first wallpaper picture.

In response to the electronic device 100 executing the wallpaper interface destruction phase lifecycle management method, the electronic device 100 needs to set the value of the mdeletsetdefaultinfo variable referenced by the main thread to null to free up memory space.

As shown in fig. 7B, after the electronic device 100 sets the value of the mdesetdefaultinfo variable referenced by the main thread to null, the value of the DelSetDefaultInfo variable referenced by the sub-thread is not null, and the value of the DelSetDefaultInfo variable referenced by the sub-thread is the address of the second wallpaper picture. Under the condition that the value of the DelSetDefaultInfo variable referenced by the sub-thread is not null, the operation that the sub-thread can normally execute to delete the first wallpaper picture is ensured, and meanwhile, the sub-thread can update the database based on the value of the DelSetDefaultInfo variable referenced by the sub-thread (such as the address of the second wallpaper picture).

S613, the electronic device 100 destroys the wallpaper interface and re-pulls up.

In response to executing the wallpaper interface destruction stage lifecycle management method, the electronic device 100 destroys and redraws the wallpaper interface. That is, the electronic device 100 destroys the wallpaper deletion interface pin, and then restarts the wallpaper setting interface.

S614, the electronic device 100 acquires the first cache file and acquires the tag of the deletion interface of the wallpaper.

Before the electronic device displays the wallpaper interface, the electronic device 100 may obtain the first cache file, and obtain the tag of the deletion interface of the wallpaper from the first cache file. The electronic device 100 may cause the electronic device 100 to continue displaying the deletion interface of the wallpaper based on the tag of the deletion interface of the wallpaper, instead of displaying only the setting interface of the wallpaper.

S615, the electronic device 100 continues to display the wallpaper deletion interface, where the wallpaper deletion interface does not include the first wallpaper picture.

The electronic device 100 continues to display a wallpaper deletion interface, where the wallpaper deletion interface does not include the first wallpaper picture. By the method, the electronic device 100 not only deletes the first wallpaper picture, but also continuously displays the wallpaper deleting interface, so that a user can continuously delete other wallpaper pictures in the wallpaper deleting interface, and the problem that the user can only display the wallpaper setting interface after executing the wallpaper picture deleting operation is avoided.

Illustratively, the deletion interface of wallpaper that electronic device 100 continues to display may be user interface 510 shown in fig. 5B. None of the user interfaces 510 include the first wallpaper picture. For example, wallpaper picture 3201 is not included in user interface 510.
