Wherein, the target electronic device may display the response result of the touch screen event on the screen, or may not display the response result of the touch screen event, which is not specifically limited in the embodiment of the present invention.

It should be noted that the screen page shared by other devices may include all content on the screen page, or part of the content. For example, it may include applications, folders, virtual buttons, pendants (such as weather, time, operator, battery), documents, etc. on the screen page.

In the screen extension method provided by the embodiment of the present invention, first, the first electronic device determines that the target electronic device shares N screen pages with the first electronic device, the target electronic device includes at least one electronic device, and each electronic device in the at least one electronic device At least one screen page is shared; then, the first electronic device may display M+N logos on the first screen page, and the M+N logos are used to indicate the local M screen pages of the first electronic device and the first electronic device. The device extension displays N screen pages shared by the target electronic device. Wherein, the first screen page is one of the M+N screen pages indicated by the above-mentioned M+N identifiers. Since the target electronic device shares N screen pages with the first electronic device, the first electronic device can expand the N screen pages into the first electronic device while keeping the local M screen pages displayed. The screen page displayed, and the M+N logo is displayed on the first screen page to prompt the user to expand the N screen pages. The user can view and operate the content displayed on the screen of other electronic devices according to the expanded screen page. The local screen page can be called up by sliding, and the content on the local screen page can be quickly and conveniently operated during the screen sharing process.

Optionally, the screen expansion method provided in the embodiment of the present invention may further include S203a, S203b, or S203c before the above S201:

S203a. The first electronic device receives a first input, where the first input triggers the first electronic device to join a screen sharing group, and the screen sharing group includes the aforementioned N screen pages.

Furthermore, S201 in the foregoing embodiment may be executed by the following S201a:

S201a: In response to the first input, the first electronic device determines N screen pages shared by the target electronic device with the first electronic device.

Exemplarily, when another electronic device initiates screen sharing, the first electronic device may join the screen sharing group by entering an agreed password, or may join the screen sharing group according to the received screen sharing request message. After joining the screen sharing group, the screen pages shared by other electronic devices that have joined the screen sharing group can be extended to the screen pages of the first electronic device.

S203b. After the first electronic device initiates screen sharing, the first electronic device receives first instruction information, where the first instruction information instructs the above N screen pages to join the screen sharing.

Exemplarily, after the user triggers the first electronic device to initiate sharing, if the first electronic device joins screen sharing (the screen sharing group is successfully created), the first electronic device updates the logo on the screen page of the first electronic device And add N screen pages shared by the electronic device.

S203c. In the case that the first electronic device has expanded K screen pages, the first electronic device receives a second instruction message, and the second instruction message instructs N-K screen pages to join screen sharing, and K is a positive integer less than N.

It should be noted that after the first electronic device has joined the screen sharing (which can be initiated by the first electronic device or other electronic devices), and the K screen pages shared by other electronic devices have been expanded, the screen An electronic device is added to the sharing group, and the electronic device shares NK screen pages, the first electronic device can update the number of identifiers on the screen page of the electronic device, and expand the K screen pages shared by the electronic device It is a screen page that can be displayed in the first electronic device.

Correspondingly, other electronic devices in the screen sharing group also add K screen pages shared by the electronic device, and the electronic device adds screen sharing pages that have been shared in the sharing group.

In the embodiment of the present invention, screen sharing and data interaction can be initiated through non-contact wireless operations (for example: Wi-Fi, Bluetooth, NFC, 4G, 5G). When multiple electronic devices establish a screen sharing group, the initiating device can trigger the establishment of a communication protocol for the screen sharing group. For example, one way of prompting to establish a screen sharing group is to generate a set of unique codes by agreement, and the electronic device starts to establish a connection after inputting the unique codes.

Optionally, the communication protocol for establishing the screen sharing group can be a centralized protocol or a decentralized protocol. In the case of a centralized communication protocol, each electronic device in the screen sharing group The operation information on the shared screen page is transmitted to the server of the decision center through the protocol, and the server of the decision center arbitrates the operation behavior to the corresponding other electronic devices, for example, the screen page displayed on the electronic device 1 by the user 2- If the operation is performed on 1, the electronic device 1 uploads the operation event to the server of the decision center, and the server of the decision center distributes the operation event to the electronic device 2. When the communication protocol is a decentralized protocol, the electronic devices communicate and interact directly. For example, if the user operates on the screen page 2-1 displayed on the electronic device 1, the electronic device 1 and the electronic device 2 directly communicate and interact.

It should be noted that when the icon is clicked on the local screen page of the electronic device A to open the APP, the local APP is opened. When you open the APP on the screen page of the electronic device A that originally belonged to the device B, it is equivalent to opening the application of the device B on the device A. This kind of opening can be realized in a second on faster network communication, so that the user does not perceive that the APP is on the remote device, such as HTML5 or quick application mode APP can be opened quickly. It is convenient for users to view APP or shared file information on other devices to determine whether they are interested and need to obtain it, and when exiting the file or APP of electronic device B, they can prompt whether the APP needs to be transferred and installed on local electronic device A.

In the embodiment of the present invention, the user may establish a screen sharing group through a third-party application, or may establish a screen sharing group through a system function.

Based on this solution, the electronic device can display M+N logos at different times, so that the electronic device can flexibly share the screen and update the logo on the screen page to remind the user that N virtual screens have been expanded, and the user can display In the case of the N virtual screens, the electronic content corresponding to the virtual screen is operated.

In the embodiment of the present invention, when the user triggers the first electronic device to initiate screen sharing, the first electronic device may display content that can be screen shared. After the first electronic device receives the screen sharing request message initiated by the target electronic device, if it receives the user's determination to join the screen sharing group, the first electronic device may also display content that can be screen shared. In the case that the user obtains the password to join the screen sharing group through other means (that is, in addition to the electronic device that initiates the screen sharing, other electronic devices can join the screen sharing group by entering the agreed password), the user enters to join the screen After sharing the password of the group, the first electronic device may also display content that can be screened.

It should be noted that, in the embodiment of the present invention, if the user selects the option to be shared by the first electronic device as part of the content on the screen, a screen page can be displayed on other electronic devices participating in screen sharing, and the background of the screen page It can be the screen background of the first electronic device where the shared content is located.

S204b. The first electronic device receives the second input.

The second input may be an input for the user to select shared content from the options to be shared displayed on the first electronic device.

It is understandable that the user can choose to share all content in a screen page, or can choose to share part of the content in a screen page.

Illustratively, for example, for three local screen pages, the user can choose to share all the screen pages of the first electronic device, and then the three screen pages can be shared, and the user can also choose to share one or two of the screen pages. Of course, the first electronic device may also choose to share part of the content on a certain screen page, for example, selecting part of APP sharing in a screen page, and selecting a document sharing in a screen page.

S204c. In response to the second input, the first electronic device determines the content shared by the first electronic device.

It can be understood that after the selection is completed, the first electronic device can share the screen page selected by the user.

Based on this solution, users can flexibly choose the content to be shared according to their needs. Users can share all screen pages, users can also share part of the screen pages, in a screen page, users can choose to share all the content in the screen page, or Choosing to share part of the content of the screen page can make the user do not need to create a new screen page when the user does not want to share some content when the screen is shared, and the operation is more convenient.

In the embodiment of the present invention, the first electronic device can distinguish the N screen pages as other electronic devices by adding marks, such as a lightweight user interface (UI), on the aforementioned N screen pages. Shared screen pages, for example, a rectangular frame is displayed on the border of a screen page shared by other electronic devices, a virtual frame is added to the entire screen, and "shared" is displayed on a screen page shared by other electronic devices, and the above-mentioned mark is not displayed on a local screen page.
