DrawerLayout – The navigation drawer is a panel that displays the app’s main navigation options on the left edge of the screen. It is hidden most of the time but is revealed when the user swipes a finger from the left edge of the screen or, while at the top level of the app, the user touches the app icon in the action bar.
Creating Drawer Layout-
To add a navigation drawer, declare your user interface with a DrawerLayout as the root view of your layout. Inside the DrawerLayout add one view that contains the main content for the screen (your primary layout when the drawer is hidden) and another view that contains the contents of the navigation drawer.
