public LeanbackSettingsFragmentCompat()

Public methods

onCreateView

public View onCreateView(
    @NonNull LayoutInflater inflater,
    ViewGroup container,
    Bundle savedInstanceState
)

Called to have the fragment instantiate its user interface view. This is optional, and non-graphical fragments can return null. This will be called between onCreate and onViewCreated.

A default View can be returned by calling Fragment in your constructor. Otherwise, this method returns null.

It is recommended to only inflate the layout in this method and move logic that operates on the returned View to onViewCreated.

If you return a View from here, you will later be called in onDestroyView when the view is being released.

Parameters
`@NonNull LayoutInflater inflater`	The LayoutInflater object that can be used to inflate any views in the fragment,
`ViewGroup container`	If non-null, this is the parent view that the fragment's UI should be attached to. The fragment should not add the view itself, but this can be used to generate the LayoutParams of the view.
`Bundle savedInstanceState`	If non-null, this fragment is being re-constructed from a previous saved state as given here.

Returns
`View`	Return the View for the fragment's UI, or null.

onPause

public void onPause()

Called when the Fragment is no longer resumed. This is generally tied to Activity.onPause of the containing Activity's lifecycle.

onPreferenceDisplayDialog

Added in 1.1.0

public boolean onPreferenceDisplayDialog(
    @NonNull PreferenceFragmentCompat caller,
    Preference pref
)

Parameters
`@NonNull PreferenceFragmentCompat caller`	The fragment containing the preference requesting the dialog
`Preference pref`	The preference requesting the dialog

Returns
`boolean`	`true` if the dialog creation has been handled

onPreferenceStartInitialScreen

Added in 1.1.0

public abstract void onPreferenceStartInitialScreen()

Called to instantiate the initial PreferenceFragment to be shown in this fragment. Implementations are expected to call startPreferenceFragment.

onResume

public void onResume()

Called when the fragment is visible to the user and actively running. This is generally tied to Activity.onResume of the containing Activity's lifecycle.

onViewCreated

public void onViewCreated(@NonNull View view, Bundle savedInstanceState)

Called immediately after onCreateView has returned, but before any saved state has been restored in to the view. This gives subclasses a chance to initialize themselves once they know their view hierarchy has been completely created. The fragment's view hierarchy is not however attached to its parent at this point.

Parameters
`@NonNull View view`	The View returned by `onCreateView`.
`Bundle savedInstanceState`	If non-null, this fragment is being re-constructed from a previous saved state as given here.

startImmersiveFragment

Added in 1.1.0

public void startImmersiveFragment(@NonNull Fragment fragment)

Displays a fragment to the user, temporarily replacing the contents of this fragment.

Parameters
`@NonNull Fragment fragment`	Fragment instance to be added.

startPreferenceFragment

Added in 1.1.0

public void startPreferenceFragment(@NonNull Fragment fragment)

Displays a preference fragment to the user. This method can also be used to display list-style fragments on top of the stack of preference fragments.

Parameters
`@NonNull Fragment fragment`	Fragment instance to be added.
