What they're doing is separating what amounts to boilerplate of the new CoordinatorLayout and AppBarLayout with the actual layout content that is specific to your app. An advantage to this is that the "shell" of the activity is consistent across device screen sizes (same toolbar and FAB, for example) while the main content can vary if you provide a different layout file for a different screen size. This is just one way of doing things and you are free to include your main content directly in the main layout file or not if it makes sense for your app. ------------------------------------------------------------------------------------------------- TreKing <http://sites.google.com/site/rezmobileapps/treking> - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
