Abstract: An application window display method and a terminal. The method includes displaying, by a terminal, a first GUI, where the first GUI includes a first application window, receiving, by the terminal, an input operation performed on the first application window, and displaying, by the terminal, a second GUI in response to the input operation, where the second GUI includes a soft keyboard at a fixed display location, and an area in the second GUI other than the soft keyboard includes the completely displayed first application window, and the display location of the soft keyboard in the second GUI partially or completely overlaps a display location of the first application window in the first GUI.

Abstract: A screen locking method and apparatus. After a first terminal establishes a connection with a second terminal, the first terminal sends to-be-displayed data to the second terminal so that the second terminal displays a first interface. The first terminal displays a second interface different from the first interface and obtains a first screen locking operation triggered by a user, where the first screen locking operation locks a screen of the second terminal. The first terminal sends a screen locking instruction to the second terminal in response to the first screen locking operation so that the second terminal enters a screen-locked state.

Abstract: A display method includes a first terminal connecting to a second terminal and obtaining a first gesture made by a user on a target shortcut in a first display interface, where the first display interface is an interface presented on the first terminal, and where target content corresponding to the target shortcut is not running in a foreground of the first terminal. Then, the first terminal sends first display data to the second terminal based on the first gesture, so that the second terminal displays the first display data in a second display interface, where the first display data is data correlated with the target content, and where the second display interface is an interface presented on the second terminal.

Abstract: A display method and an apparatus that relates to the field of communications technologies, to avoid a problem that a process of a currently running application cannot continue due to disconnection of a terminal when the terminal performs multi-screen display. The method includes a first terminal sending first display data to a second terminal after the first terminal connects to the second terminal, so that the second terminal displays a first interface. In this case, the first terminal displays a second interface (the second interface is different from the first interface). The first terminal disconnects from the second terminal; and after the first terminal reconnects to the second terminal, the first terminal may send second display data to the second terminal, so that the second terminal displays a third interface correlated with the first interface.

Abstract: Embodiments of this application provide a multi-window display method, a first electronic device, and a second electronic device. The method is applied to the first electronic device and the second electronic device that communicate with each other. When a plurality of applications run on a mobile phone, a plurality of windows of the mobile phone can be displayed on a PC, and each window is correspondingly used to display a different application. A user can perform an operation on each mobile phone application by using a window that corresponds to the mobile phone application and that is displayed on the PC. In addition, the operation performed by the user on the mobile phone application on the PC does not affect use of another function of the user on the mobile phone. This improves office efficiency such as file sharing, and improves user experience.

Abstract: The method includes: in a projection scenario, a first device displays, in a first display area of a display, a first user interface of a first application running on the first device, and displays, in a second display area of the display, a second user interface that is being displayed by a second device. The second user interface includes one or more file objects. A user may drag a first file object on the second user interface to the first user interface to release, so that the second device transfers the first file object to the first device. Then, the first device stores the first file object, and provides the first file object for the first application for processing. In embodiments, application data of one device can be directly shared to an application of another device without switching a user interface for a plurality of times.
