Public methods

public static final boolean navigateUp(@NonNull NavController navController, Openable openableLayout)

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 Openable layout, you should call NavController.navigateUp directly.

Parameters
`@NonNull NavController navController`	The NavController that hosts your content.
`Openable openableLayout`	The Openable layout 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.

public static final boolean navigateUp(
    @NonNull NavController navController,
    @NonNull 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.fallbackOnNavigateUpListener will be called to provide additional control.

Parameters
`@NonNull NavController navController`	The NavController that hosts your content.
`@NonNull AppBarConfiguration configuration`	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.

public static final boolean onNavDestinationSelected(
    @NonNull MenuItem item,
    @NonNull 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
`@NonNull MenuItem item`	The selected MenuItem.
`@NonNull 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.

@NavigationUiSaveStateControl
public static final boolean onNavDestinationSelected(
    @NonNull MenuItem item,
    @NonNull NavController navController,
    boolean saveState
)

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
`@NonNull MenuItem item`	The selected MenuItem.
`@NonNull NavController navController`	The NavController that hosts the destination.
`boolean saveState`	Whether the NavController should save the back stack state. This must always be `false`: leave this parameter off entirely to use the non-experimental version of this API, which saves the state by default.

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

public static final void setupActionBarWithNavController(
    @NonNull AppCompatActivity activity,
    @NonNull NavController navController,
    Openable openableLayout
)

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 Openable layout is non null. On all other destinations, the ActionBar will show the Up button. Call navigateUp to handle the Up button.

Destinations that implement androidx.navigation.FloatingWindow will be ignored.

Parameters
`@NonNull AppCompatActivity activity`	The activity hosting the action bar that should be kept in sync with changes to the NavController.
`@NonNull NavController navController`	The NavController whose navigation actions will be reflected in the title of the action bar.
`Openable openableLayout`	The Openable layout that should be toggled from the home button

    @NonNull AppBarConfiguration configuration
)

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 AppBarConfiguration you provide controls how the Navigation button is displayed. Call navigateUp to handle the Up button.

public static final void setupWithNavController(
    @NonNull Toolbar toolbar,
    @NonNull NavController navController,
    Openable openableLayout
)

Sets up a Toolbar for use with a NavController.

By calling this method, the title in the Toolbar 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 Toolbar will show the drawer icon if the given Openable layout is non null. On all other destinations, the Toolbar will show the Up button. This method will call navigateUp when the Navigation button is clicked.

Destinations that implement androidx.navigation.FloatingWindow will be ignored.

Parameters
`@NonNull Toolbar toolbar`	The Toolbar that should be kept in sync with changes to the NavController.
`@NonNull NavController navController`	The NavController whose navigation actions will be reflected in the title of the Toolbar.

If the NavigationView is directly contained with an Openable layout, it will be closed when a menu item is selected.

Similarly, if the NavigationView has a BottomSheetBehavior associated with it (as is the case when using a com.google.android.material.bottomsheet.BottomSheetDialog), the bottom sheet will be hidden when a menu item is selected.

Parameters
`@NonNull NavigationView navigationView`	The NavigationView that should be kept in sync with changes to the NavController.
`@NonNull NavController navController`	The NavController that supplies the primary and secondary menu. Navigation actions on this NavController will be reflected in the selected item in the NavigationView.
