Public constructors

DialogFragmentNavigator

public DialogFragmentNavigator (Context context, 
                FragmentManager manager)

Parameters
context	Context
manager	FragmentManager

Public methods

createDestination

public DialogFragmentNavigator.Destination createDestination ()

Construct a new NavDestination associated with this Navigator.

Any initialization of the destination should be done in the destination's constructor as it is not guaranteed that every destination will be created through this method.

Returns
DialogFragmentNavigator.Destination	a new NavDestination

navigate

public NavDestination navigate (DialogFragmentNavigator.Destination destination, 
                Bundle args, 
                NavOptions navOptions, 
                Navigator.Extras navigatorExtras)

Navigate to a destination.

Requests navigation to a given destination associated with this navigator in the navigation graph. This method generally should not be called directly; NavController will delegate to it when appropriate.

Parameters
destination	DialogFragmentNavigator.Destination: destination node to navigate to
args	Bundle: arguments to use for navigation
navOptions	NavOptions: additional options for navigation
navigatorExtras	Navigator.Extras: extras unique to your Navigator.

Returns
NavDestination	The NavDestination that should be added to the back stack or null if no change was made to the back stack (i.e., in cases of single top operations where the destination is already on top of the back stack).

onRestoreState

public void onRestoreState (Bundle savedState)

Restore any state previously saved in onSaveState(). This will be called before any calls to navigate(NavDestination, Bundle, NavOptions, Navigator.Extras) or popBackStack().

Calls to createDestination() should not be dependent on any state restored here as createDestination() can be called before the state is restored.

Parameters
savedState	Bundle: The state previously saved

onSaveState

public Bundle onSaveState ()

Called to ask for a Bundle representing the Navigator's state. This will be restored in onRestoreState(Bundle).

Returns
Bundle

popBackStack

public boolean popBackStack ()

Attempt to pop this navigator's back stack, performing the appropriate navigation.

Implementations should return true if navigation was successful. Implementations should return false if navigation could not be performed, for example if the navigator's back stack was empty.

Returns
boolean	true if pop was successful
