Android provides four generalized size qualifiers: small, medium, large, and xlarge. Defining multiple sets of layout resources enables you to create a single app with a flexible and adaptable interface for different screen configurations. At runtime, the device reports its configuration, and Android chooses the appropriate matching layout resources for that screen. Provide Multiple Layouts for Different ScreensĪnother way to provide an app that looks good on different screen types is to define multiple XML layout resources for different screen configurations. You can take advantage of the larger screen size by, for example, including more content or by making better use of portrait and landscape modes. In addition, when porting an app from a smaller screen to a larger one, consider redesigning your app's user interface altogether. See Use "wrap_content" and "match_parent" for more information.
A flexible layout enables your app's user interface (UI) to dynamically scale to different screen sizes, densities, and aspect ratios at runtime. To address these issues, design your app to use a flexible layout.
