Abstract: A display method includes an electronic device that runs a first application and displays a first interface in a form of a floating window in response to a first operation. The first interface includes a first title bar and a first content display part. The electronic device displays a second interface in response to a second operation. The second interface includes the first title bar, the first content display part, and a second content display part adjacent to the first content display part. The first title bar includes a first subtitle label corresponding to the second content display part.

Abstract: In a process of accepting projection by a first device, a second device obtains first information, to adaptively adjust one or more of a frame rate corresponding to a projected interface, a size of an application display region corresponding to a projected interface, display resolution of the second device, or video resolution corresponding to a projected interface. In this way, an image processing resource and a processing capability of the device can be allocated on demand to enhance a projected picture and reduce load of the second device.

Abstract: A method includes: A source device sends, to a destination device, application information of at least one source device application installed on the source device. The destination device displays an icon of the at least one source device application in a first interface, and displays, in the first interface, an icon of at least one destination device application installed on the destination device. In response to an operation on an icon of a first application in the source device application, the destination device obtains first display data generated during running of the first application on the source device. The destination device displays an application window of the first application based on the first display data. In response to an operation on an icon of a second application in the destination device application, the destination device starts the second application, and displays an application window of the second application.

Abstract: An application interface display method includes, when an electronic device detects a first user operation of scaling an application interface, a system display pixel density is generated corresponding to the first user operation, where the system display pixel density is not a system display pixel density set by a current system. A change of a system configuration triggers an update of an application setting. After the system display pixel density dispatched by the first user operation is obtained, a first application loads a corresponding application resource and displays an upscale or downscale application interface.
