Abstract: an interface display method and an electronic device. In the method, a target application in the electronic device may generate a view tree based on a first display window whose width is less than a width of an actual display window. The electronic device may generate, based on a second display window, a user interface corresponding to the view tree. The electronic device may stretch a second view node that may affect aesthetics of the user interface, so that a width of the second view node is adapted to a width of the second display window. For a first view node that does not affect the aesthetics of the user interface, a current state of the first view node in the user interface is maintained.
