Xamarin.Android - Navigation Drawer
This example illustrates a common usage of the DrawerLayout widget in the Android support library. When a navigation (left) drawer is present, the host activity should detect presses of the action bar's Up affordance as a signal to open and close the navigation drawer. The ActionBarDrawerToggle facilitates this behavior. Items within the drawer should fall into one of two categories:
- View switches. A view switch follows the same basic policies as list or tab navigation in that a view switch does not create navigation history. This pattern should only be used at the root activity of a task, leaving some form of Up navigation active for activities further down the navigation hierarchy.
- Selective Up. The drawer allows the user to choose an alternate parent for Up navigation. This allows a user to jump across an app's navigation hierarchy at will. The application should treat this as it treats Up navigation from a different task, replacing the current task stack using TaskStackBuilder or similar. This is the only form of navigation drawer that should be used outside of the root activity of a task.
Right side drawers should be used for actions, not navigation. This follows the pattern established by the Action Bar that navigation should be to the left and actions to the right. An action should be an operation performed on the current contents of the window, for example enabling or disabling a data overlay on top of the current content.
