Public functions

newInstanceMulti

Added in 1.1.0
java-static fun newInstanceMulti(key: String!): LeanbackListPreferenceDialogFragmentCompat!

Create a new LeanbackListPreferenceDialogFragmentCompat.

Parameters
key: String!

The key of MultiSelectListPreference it will be created from.

Returns
LeanbackListPreferenceDialogFragmentCompat!

A new LeanbackListPreferenceDialogFragmentCompat to display.

newInstanceSingle

Added in 1.1.0
java-static fun newInstanceSingle(key: String!): LeanbackListPreferenceDialogFragmentCompat!

Create a new LeanbackListPreferenceDialogFragmentCompat.

Parameters
key: String!

The key of ListPreference it will be created from.

Returns
LeanbackListPreferenceDialogFragmentCompat!

A new LeanbackListPreferenceDialogFragmentCompat to display.

onCreate

fun onCreate(savedInstanceState: Bundle!): Unit

Called to do initial creation of a fragment. This is called after onAttach and before onCreateView.

Note that this can be called while the fragment's activity is still in the process of being created. As such, you can not rely on things like the activity's content view hierarchy being initialized at this point. If you want to do work once the activity itself is created, add a androidx.lifecycle.LifecycleObserver on the activity's Lifecycle, removing it when it receives the CREATED callback.

Any restored child fragments will be created before the base Fragment.onCreate method returns.

Parameters
savedInstanceState: Bundle!

If the fragment is being re-created from a previous saved state, this is the state.

onCreateView

fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup!,
    savedInstanceState: Bundle!
): View!

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
inflater: LayoutInflater

The LayoutInflater object that can be used to inflate any views in the fragment,

container: ViewGroup!

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.

savedInstanceState: Bundle!

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.

onSaveInstanceState

fun onSaveInstanceState(outState: Bundle): Unit

Called to ask the fragment to save its current dynamic state, so it can later be reconstructed in a new instance if its process is restarted. If a new instance of the fragment later needs to be created, the data you place in the Bundle here will be available in the Bundle given to onCreate, onCreateView, and onViewCreated.

This corresponds to Activity.onSaveInstanceState(Bundle) and most of the discussion there applies here as well. Note however: this method may be called at any time before onDestroy. There are many situations where a fragment may be mostly torn down (such as when placed on the back stack with no UI showing), but its state will not be saved until its owning activity actually needs to save its state.

Parameters
outState: Bundle

Bundle in which to place your saved state.
