According to whether the power supply of the display screen is provided, the electronic device can have two states: the on-screen state and the off-screen state. The screen off state means that the power of the display is turned off, and the display does not display any interface elements. The bright screen state means that part or all of the display screen is lit, and interface elements can be displayed on the display screen. When the display screen of an electronic device emits light by the pixels (for example, the display screen is an OLED screen or an AMOLED screen), lighting up part of the display screen can mean lighting up some pixels on the display screen, and lighting up all the display screens can mean Light up all pixels on the display.

It is understandable that whether the electronic device is locked, and whether the electronic device provides power supply for the display screen are independent of each other. That is, in the locked state, the electronic device may be in the on-screen state at the same time, or may be in the off-screen state at the same time.

Messages pushed by the server corresponding to the application to the electronic device, such as news messages sent to the electronic device by the WeChat server, or sent to the electronic device by the server of the application store Application update news of electronic equipment, etc. 2. Messages generated locally by electronic devices, such as missed calls, alarms, or reminders.

In some embodiments of the present application, the unread message of the application program may refer to a message that the electronic device has not yet presented specific content. Wherein, the specific content of the message presented by the electronic device refers to that the electronic device starts the corresponding application and displays the specific content of the message or broadcasts the specific content of the message by voice. It is understandable that the electronic device displays the notification information of the new message on the notification bar or the lock screen interface after receiving the new message, which does not belong to the specific content of the new message presented by the electronic device.

For example, when an instant messaging application (such as WeChat) installed on an electronic device receives a new message (such as the text message "Hello") from a contact, the electronic device displays the message on the lock screen The text notification message "WeChat received 1 new message", the text notification message "xx sent 1 new message" displayed in the notification bar at the top area of the display screen, etc., are not specific to the electronic device presenting the new message. content. After the user opens WeChat and selects the contact to open the chat interface with the contact, the electronic device can display the text message "Hello", and the electronic device presents the specific content of the new message.

In some other embodiments of the present application, the unread message of the application may refer to a message corresponding to the message type set by the user to need to be reminded in the application, and the electronic device has not yet presented a message with specific content. For example, for WeChat, if the user sets Do Not Disturb to a contact, after the electronic device receives a new message sent by the contact, even if the electronic device does not display the new message, the new message does not belong to WeChat Of unread messages.

In the following embodiments of the present application, the indication information of the application program is used to indicate the application program. The indication information of the application program may include the icon, text information, animation, or other types of visual interface elements of the application program. Among them, the icon of the application program may include: 1. The icon of a single application program, such as the icon of WeChat, the icon of mailbox, the icon of Twitter, etc. 2.

The inside of the first circle is filled with black, indicating the user as shown in 5B Interface 52 is the first lock screen interface. Referring to FIG. 5C, the page indicator 506 is used to indicate that the user interface 53 is the second lock screen interface.

When an electronic device lights up all the display screens to display the icons of applications with unread messages, the electronic device can use the following strategies to arrange the icons of applications with unread messages on the lock screen:

(1) Arrange application icons in order according to the number of unread messages. The icons of applications with more unread messages are arranged first, or the icons of applications with fewer unread messages are arranged first. Exemplarily, referring to FIG. 5A or FIG. 5B-5C, the electronic device may sequentially arrange the icons of the application programs that have unread messages according to the number of unread messages from as few to as many.

(2) According to the time when the application program received the unread message last time, that is, according to the generation time of the latest unread message, from morning to night, or from night to morning, sequentially arrange the icons of the application programs with unread messages.

(3) According to the download time of the application, that is, according to the installation time of the application, from morning to night, or from night to morning, the icons of the applications with unread messages are arranged in sequence.

It is not limited to the several strategies mentioned above. In specific implementation, the electronic device can also use other strategies to arrange the icons of the application programs with unread messages on the lock screen interface, which is not limited in the embodiment of the present application. For example, the electronic device can also arrange the applications with unread messages on the lock screen according to the order in which the applications are arranged on the desktop or the home screen, according to the initial order of the applications, or according to the frequency of use of the applications, etc. Icon. For another example, the electronic device may also randomly arrange the icons of applications with unread messages on the lock screen interface.

Referring to FIG. 6A, the user interface 61 may include: icons of applications that currently have unread messages. In some embodiments, if there are currently a large number of applications with unread messages, the electronic device may switch and display different applications with unread messages on the user interface 61 every preset time period (for example, 5 seconds). Icon. For example, if the current number of applications with unread messages is 20, the electronic device can first display the 1-10 applications with unread messages on the display screen, and display the 11-20 applications after 5 seconds. An application with unread messages will display the 1-10th application with unread messages in a loop after 5 seconds.

When the electronic device lights up part of the display screen to display the icons of the application programs with unread messages, the strategy used when arranging these icons can refer to the previous embodiment when the electronic device lights up all the display screens to show the presence of unread messages. The strategy used by the icon of the application will not be repeated here.

Referring to FIG. 6A, when the electronic device displays an icon of an application with an unread message on the lock screen interface, it may also display a corner mark on the icon, and the corner mark contains a value. Here, the shape of the corner marker, the display position, and the determination method of the value in the corner marker can refer to the related descriptions in Figures 5A to 5C above.

Through the embodiment of FIG. 6A, the electronic device can display the icon of the application program with the unread message on the lock screen interface. In some embodiments, a subscript containing a numerical value may also be displayed on the icon, and the numerical value is the number of unread messages in the corresponding application. This allows the user to know which applications currently have unread messages through the lock screen interface without having to unlock.

It is not limited to displaying icons of applications with unread messages on the lock screen interface, and the electronic device may also prompt the user which applications currently have unread messages in other ways. For example, the user can also display text information on the lock screen interface to remind the user which applications currently have unread messages. Exemplarily, referring to FIG. 6B, FIG. 6B shows another possible lock screen interface provided by an electronic device. The lock screen interface prompts the user which applications currently have unread messages through text information. As shown in FIG. 6B, the user interface 62 includes text information, which is used to prompt the user that there is currently an application program of unread messages. The text information may include the name of the application program that currently has an unread message. In some embodiments, the text information may also include the number of unread messages in each application.

In some embodiments, if there are currently a large number of applications with unread messages, the electronic device can switch to display different text information on the user interface 62 every preset time (for example, 5 seconds) to remind the user that the current Which applications have unread messages.

The way shown in FIGS. 6A and 6B is to light up part of the display screen to prompt the user which applications currently have unread messages, which saves more power than the way to light up all the display screens.

Through any of the above-mentioned implementations in FIG. 5A-5D, FIG. 6A or FIG. 6B, the electronic device can display the indication information of the application program that currently has unread messages on the lock screen interface, so that the user does not need to unlock the electronic device Status, through the lock screen interface, you can quickly and easily understand which applications have unread messages. Such a display method is more intuitive, simple and effective for the user, can improve the efficiency of the user for viewing unread messages, and enhance the user's experience of using the electronic device.

In some embodiments, the icon and text information of the application with unread messages displayed on the lock screen interface of the electronic device can be used to receive user operations (such as touch operations). In response to the user operations, the electronic device can perform the following Any operation:

1. The electronic device prompts the user to unlock. After detecting the operation for switching the electronic device from the locked state to the unlocked state, the electronic device starts the application, so that the user can view the unread message in the application. The application is the application corresponding to the icon or text information that the user operates on. Here, the operation for switching the electronic device from the locked state to the unlocked state can refer to the manner in which the electronic device is switched from the locked state to the unlocked state in the foregoing embodiment, which will not be repeated here. Exemplarily, refer to 7, which shows a way for the electronic device to prompt the user to unlock.

For example, when a user operation (such as a touch operation) acting on the icon 503D shown in FIG. 5A is detected, or when it is detected that it acts on the text information "application store: 7 unread messages" shown in FIG. 5D In response to a user operation (such as a touch operation), the electronic device prompts the user to unlock. After the user unlocks the electronic device, the electronic device can run the application store and display the user interface provided by the application store.

It is understandable that, in some embodiments, the electronic device can directly detect the user operation received by the icon and text information of the application program with unread messages on the lock screen interface to switch the electronic device from the locked state to The operation in the unlocked state does not need to prompt the user.

In some embodiments, the icon of the application with the unread message on the lock screen interface, the user operation received by the text message, and the operation for switching the electronic device from the locked state to the unlocked state may be the same operation . For example, when the electronic device has the icon of the application program of the unread message on the lock screen interface, and the user operation (such as touch operation) received on the text message, the user's fingerprint can be collected at the same time, if the collected fingerprint and the pre-stored fingerprint Same, the electronic device is switched from the locked state to the unlocked state.

2. The electronic device directly starts the application, so that the user can view the unread messages in the application. The application is the application corresponding to the icon or text information that the user operates on. Specifically, in some embodiments, part of the application can be directly opened in the locked state, that is, the electronic device can open the part of the application without being unlocked, and the part of the application can be set by the user. In some embodiments, after the electronic device directly starts the application, it can only display part of the content of the application (for example, the unread message of the application), and the remaining content (for example, the main interface of the application) can be displayed on the electronic device. Display after unlocking.

It is understandable that the user interfaces shown in FIGS. 5A-5D, 6A, 6B, and 7 are only examples, and should not constitute a limitation to the present application.

When the electronic device displays the interface described in Figures 5A-5D, Figure 6A or Figure 6B, if the user turns off the "lock screen aggregation" of the electronic device, the electronic device can redisplay the lock screen before the "lock screen aggregation" is turned on interface. Refer to Figure 4A or Figure 4B for the lock screen interface before the "lock screen aggregation" is turned on. There are many ways for users to turn off the "lock screen aggregation" of electronic devices. For example, you can turn off the "lock screen aggregation" by pulling down the "lock screen aggregation" switch control in the notification bar, or you can turn off the "lock screen aggregation" by shaking the electronic device twice. The embodiment of the present application does not impose restrictions on the “screen aggregation”, turning off the “lock screen aggregation” by voice, etc.

In the embodiment of the present application, the electronic device can receive messages of various installed applications in the on and off states, and count whether there are unread messages in each application. Here, the message of the application program received by the electronic device may be pushed by the server to the electronic device, or may be generated when the electronic device runs the application program. The electronic device may continuously receive or periodically receive messages about the existence of various installed applications. In some embodiments, the electronic device may also count the number of unread messages in each application.

Based on the software architecture of the electronic device, the following describes how the electronic device displays the indication information of the application program with unread messages on the lock screen interface. The indication information can be an icon of an application program or text information.

Referring to FIG. 8, FIG. 8 shows a schematic diagram of the data flow trend involved when the electronic device displays the indication information of the application with unread messages on the lock screen interface after the "lock screen aggregation" is turned on. It is understandable that what is shown in FIG. 8 is only part of the software modules in the electronic device, and should not be limited to the software architecture of the electronic device.

In some embodiments, the push message receiving module in the application framework layer may receive the message pushed by the server to the electronic device. The push message receiving module can send the received message to the corresponding application in the application layer. The applications running in the application layer can receive messages sent by the push message receiving module, such as news messages sent by the WeChat server to the electronic device, and application update messages sent by the server of the application store to the electronic device.

In other embodiments, applications running in the application layer can generate application messages, such as alarm clocks or reminders.

The application running in the application layer calls the getContentResolver().call(Uri,String,String,Bundle) interface to notify the desktop launcher of the current unread messages. In this interface, the first parameter Uri is used to indicate the name of the target module of the notification. For example, it can be Uri.parse("content://com.huawei.android.desktop launcher.settings/badge/"), Indicates that the notification will be delivered to the desktop launcher. The second parameter String indicates the name of the interface, for example, it can be "change_badge". The third parameter String is not used in this application and can be left blank, for example, it can be "null". The fourth parameter Bundle is used to indicate the content that needs to be transmitted to the desktop launcher, including which application calls the interface, the number of unread messages that exist in the application, and so on. The Bundle object contains three values, namely the package name extra.putString("package",packageName), the class name extra.putString("class",className), and the number of unread messages extra.putInt("badgenumber", count). The className can be the name of the main Activity of the application.

The desktop launcher is used to manage the desktop (that is, the home screen) of the electronic device and the lock screen interface. The desktop launcher maintains or stores information about unread messages that exist in various applications. In some embodiments, this information can be implemented as a list of unread messages. Exemplarily, referring to Table 1, Table 1 shows a possible number of unread messages.

Table 1 Number of unread messages

After the desktop launcher receives the content transmitted by the application, it can update the related information of the unread messages existing in each application, for example, it can update the number table of unread messages shown in Table 1.

If the “lock screen aggregation” is enabled on the electronic device, the desktop launcher can call the canvas module according to the information related to the unread messages in each application that is maintained or stored, so that the canvas module can call the display driver through the openGL interface, so that the display The lock screen provided by the screen prompts the user which applications currently have unread messages.

Here, the desktop launcher can call the canvas module and the display driver to display the instructions of the application with unread messages on the lock screen in the following situations:

(1) When the screen is off, the electronic device receives a press operation on the physical power button (power button), receives a press operation (one or two press operations) on the physical volume button, and receives a press operation for lighting all Voice commands or gesture commands on the screen, etc.

For example, when the electronic device receives a pressing operation (one or two pressing operations) on the physical volume key, the sensor driver can call the pressure sensor provided under the physical volume key to receive the operation, and package the pressing operation The input event is transmitted to the input subsystem (input subsystem) in the application framework layer. The input subsystem can upload the input event to the desktop launcher, trigger the desktop launcher to call the canvas module and the display driver to display instructions on the lock screen interface.

(2) When the electronic device is in the unlocked state and the screen is on, no user operation is received within a preset time period (for example, 10 seconds).

For example, when the electronic device is in the unlocked state and the screen is on, if the kernel layer does not generate any input events, the desktop launcher calls the canvas module and the display driver displays instructions on the lock screen interface.
