Public methods

navigateUp

public static boolean navigateUp (NavController navController, 
                DrawerLayout drawerLayout)

Handles the Up button by delegating its behavior to the given NavController. This should generally be called from AppCompatActivity.onSupportNavigateUp().

If you do not have a DrawerLayout, you should call NavController.navigateUp() directly.

Parameters
navController	NavController: The NavController that hosts your content.
drawerLayout	DrawerLayout: The DrawerLayout that should be opened if you are on the topmost level of the app.

Returns
boolean	True if the NavController was able to navigate up.

navigateUp

public static boolean navigateUp (NavController navController, 
                AppBarConfiguration configuration)

Handles the Up button by delegating its behavior to the given NavController. This is an alternative to using NavController.navigateUp() directly when the given AppBarConfiguration needs to be considered when determining what should happen when the Up button is pressed.

In cases where no Up action is available, the AppBarConfiguration.getFallbackOnNavigateUpListener() will be called to provide additional control.

Parameters
navController	NavController: The NavController that hosts your content.
configuration	AppBarConfiguration: Additional configuration options for determining what should happen when the Up button is pressed.

Returns
boolean	True if the NavController was able to navigate up.

onNavDestinationSelected

public static boolean onNavDestinationSelected (MenuItem item, 
                NavController navController)

Attempt to navigate to the NavDestination associated with the given MenuItem. This MenuItem should have been added via one of the helper methods in this class.

Importantly, it assumes the menu item id matches a valid action id or destination id to be navigated to.

By default, the back stack will be popped back to the navigation graph's start destination. Menu items that have android:menuCategory="secondary" will not pop the back stack.

Parameters
item	MenuItem: The selected MenuItem.
navController	NavController: The NavController that hosts the destination.

Returns
boolean	True if the NavController was able to navigate to the destination associated with the given MenuItem.

setupActionBarWithNavController

public static void setupActionBarWithNavController (AppCompatActivity activity, 
                NavController navController, 
                DrawerLayout drawerLayout)

Sets up the ActionBar returned by AppCompatActivity.getSupportActionBar() for use with a NavController.

By calling this method, the title in the action bar will automatically be updated when the destination changes (assuming there is a valid label).

The start destination of your navigation graph is considered the only top level destination. On the start destination of your navigation graph, the ActionBar will show the drawer icon if the given DrawerLayout is non null. On all other destinations, the ActionBar will show the Up button. Call navigateUp(NavController, DrawerLayout) to handle the Up button.

Parameters
activity	AppCompatActivity: The activity hosting the action bar that should be kept in sync with changes to the NavController.
navController	NavController: The NavController whose navigation actions will be reflected in the title of the action bar.
drawerLayout	DrawerLayout: The DrawerLayout that should be toggled from the home button

Sets up the ActionBar returned by AppCompatActivity.getSupportActionBar() for use with a NavController.

By calling this method, the title in the action bar will automatically be updated when the destination changes (assuming there is a valid label).

The start destination of your navigation graph is considered the only top level destination. On all other destinations, the ActionBar will show the Up button. Call NavController.navigateUp() to handle the Up button.

Parameters
