Summary

Public methods
`static View.OnClickListener`	`createNavigateOnClickListener(NavDirections directions)` Create an `View.OnClickListener` for navigating to a destination via a generated `NavDirections`.
`static View.OnClickListener`	`createNavigateOnClickListener(int resId)` Create an `View.OnClickListener` for navigating to a destination.
`static View.OnClickListener`	`createNavigateOnClickListener(int resId, Bundle args)` Create an `View.OnClickListener` for navigating to a destination.
`static NavController`	`findNavController(Activity activity, int viewId)` Find a `NavController` given the id of a View and its containing `Activity`.
`static NavController`	`findNavController(View view)` Find a `NavController` given a local `View`.
`static void`	`setViewNavController(View view, NavController controller)` Associates a NavController with the given View, allowing developers to use `findNavController(View)` and `findNavController(Activity, int)` with that View or any of its children to retrieve the NavController.

Public methods

public static View.OnClickListener createNavigateOnClickListener (NavDirections directions)

Create an View.OnClickListener for navigating to a destination via a generated NavDirections.

Parameters
`directions`	`NavDirections`: directions that describe this navigation operation

Returns
`View.OnClickListener`	a new click listener for setting on an arbitrary view

createNavigateOnClickListener

public static View.OnClickListener createNavigateOnClickListener (int resId)

Create an View.OnClickListener for navigating to a destination. This supports both navigating via an action and directly navigating to a destination.

Parameters
`resId`	`int`: an `action` id or a destination id to navigate to when the view is clicked

Returns
`View.OnClickListener`	a new click listener for setting on an arbitrary view

createNavigateOnClickListener

public static View.OnClickListener createNavigateOnClickListener (int resId, 
                Bundle args)

Create an View.OnClickListener for navigating to a destination. This supports both navigating via an action and directly navigating to a destination.

Parameters
`resId`	`int`: an `action` id or a destination id to navigate to when the view is clicked
`args`	`Bundle`: arguments to pass to the final destination

Returns
`View.OnClickListener`	a new click listener for setting on an arbitrary view

findNavController

public static NavController findNavController (Activity activity, 
                int viewId)

Find a NavController given the id of a View and its containing Activity. This is a convenience wrapper around findNavController(View).

This method will locate the NavController associated with this view. This is automatically populated for the id of a NavHost and its children.

Parameters
`activity`	`Activity`: The Activity hosting the view
`viewId`	`int`: The id of the view to search from

Returns
`NavController`	the `NavController` associated with the view referenced by id

Throws
`IllegalStateException`	if the given viewId does not correspond with a `NavHost` or is not within a NavHost.

findNavController

public static NavController findNavController (View view)

Find a NavController given a local View.

This method will locate the NavController associated with this view. This is automatically populated for views that are managed by a NavHost and is intended for use by various listener interfaces.

Parameters
`view`	`View`: the view to search from

Returns
`NavController`	the locally scoped `NavController` to the given view

Throws
`IllegalStateException`	if the given view does not correspond with a `NavHost` or is not within a NavHost.

public static void setViewNavController (View view, 
                NavController controller)

Associates a NavController with the given View, allowing developers to use findNavController(View) and findNavController(Activity, int) with that View or any of its children to retrieve the NavController.

This is generally called for you by the hosting NavHost.

Parameters
`view`	`View`: View that should be associated with the given NavController
`controller`	`NavController`: The controller you wish to later retrieve via `findNavController(View)`
