Abstract: An interface display method and a device are described. An original interface may be moved to reserve space for displaying an interface of a first application such as a voice assistant, so that the interface of the first application does not block the original interface. This helps a user interact with the original interface and the interface of the first application. For example, an electronic device displays a first interface. The electronic device detects an operation in which the user indicates to start a first application. The electronic device displays the first interface in a first area of a screen, and displays a second interface in a second area of the screen. The second interface is an interface of the first application, and the first area does not overlap the second area.
