inline fun AppBarConfiguration(
    navGraph: NavGraph,
    drawerLayout: Openable? = null,
    noinline fallbackOnNavigateUpListener: () -> Boolean = { false }
): AppBarConfiguration

Configuration options for NavigationUI methods that interact with implementations of the app bar pattern such as androidx.appcompat.widget.Toolbar, com.google.android.material.appbar.CollapsingToolbarLayout, and androidx.appcompat.app.ActionBar.

    topLevelDestinationIds: Set<Int>,
    drawerLayout: Openable? = null,
    noinline fallbackOnNavigateUpListener: () -> Boolean = { false }
): AppBarConfiguration

Configuration options for NavigationUI methods that interact with implementations of the app bar pattern such as androidx.appcompat.widget.Toolbar, com.google.android.material.appbar.CollapsingToolbarLayout, and androidx.appcompat.app.ActionBar.

inline fun AppBarConfiguration(
    topLevelMenu: Menu,
    drawerLayout: Openable? = null,
    noinline fallbackOnNavigateUpListener: () -> Boolean = { false }

fun NavController.navigateUp(appBarConfiguration: AppBarConfiguration): Boolean

Handles the Up button by delegating its behavior to the given NavController.

fun NavController.navigateUp(drawerLayout: Openable?): Boolean

Handles the Up button by delegating its behavior to the given NavController.

This is equivalent to calling NavController.navigateUp if the Openable layout is null.

fun MenuItem.onNavDestinationSelected(navController: NavController): Boolean

Attempt to navigate to the NavDestination associated with this MenuItem.

Importantly, it assumes the getItemId 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.

fun AppCompatActivity.setupActionBarWithNavController(
    navController: NavController,
    configuration: AppBarConfiguration = AppBarConfiguration(navController.graph)
): Unit

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.

You are responsible for calling NavController.navigateUp to handle the Navigation button. Typically this is done in AppCompatActivity.onSupportNavigateUp.

fun AppCompatActivity.setupActionBarWithNavController(
    navController: NavController,
    drawerLayout: DrawerLayout?
): Unit

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.

You are responsible for calling NavController.navigateUp to handle the Navigation button. Typically this is done in AppCompatActivity.onSupportNavigateUp.

fun NavigationBarView.setupWithNavController(navController: NavController): Unit

Sets up a NavigationBarView for use with a NavController. This will call android.view.MenuItem.onNavDestinationSelected when a menu item is selected.

The selected item in the NavigationView will automatically be updated when the destination changes.

fun NavigationView.setupWithNavController(navController: NavController): Unit

Sets up a NavigationView for use with a NavController. This will call android.view.MenuItem.onNavDestinationSelected when a menu item is selected.

The selected item in the NavigationView will automatically be updated when the destination changes.

fun Toolbar.setupWithNavController(
    navController: NavController,
    configuration: AppBarConfiguration = AppBarConfiguration(navController.graph)
): Unit

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 AppBarConfiguration you provide controls how the Navigation button is displayed and what action is triggered when the Navigation button is tapped.

This method will call NavController.navigateUp when the navigation icon is clicked.

fun Toolbar.setupWithNavController(
    navController: NavController,
    drawerLayout: DrawerLayout?
): Unit

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 drawerLayout is non null. On all other destinations, the Toolbar will show the Up button.

This method will call NavController.navigateUp when the navigation icon is clicked.

fun CollapsingToolbarLayout.setupWithNavController(
    toolbar: Toolbar,
    navController: NavController,
    configuration: AppBarConfiguration = AppBarConfiguration(navController.graph)
): Unit

Sets up a CollapsingToolbarLayout and 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 AppBarConfiguration you provide controls how the Navigation button is displayed and what action is triggered when the Navigation button is tapped.

This method will call NavController.navigateUp when the navigation icon is clicked.

fun CollapsingToolbarLayout.setupWithNavController(
    toolbar: Toolbar,
    navController: NavController,
    drawerLayout: DrawerLayout?
): Unit

Sets up a CollapsingToolbarLayout and 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 drawerLayout is non null. On all other destinations, the Toolbar will show the Up button.

This method will call NavController.navigateUp when the Navigation button is clicked.
