The * ActionBarDrawerToggle facilitates this behavior. * Items within the drawer should fall into one of two categories:</p> * <p/> * <ul> * <li><strong>View switches</strong>. 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.</li> * <li><strong>Selective Up</strong>. 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.</li> * </ul> * <p/> * <p>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.</p> */ public class ContainerActivity extends BaseActivity { private DrawerLayout mDrawerLayout;
