DetailsSupportFragment

public class DetailsSupportFragment extends BaseSupportFragment


A fragment for creating Leanback details screens.

A DetailsSupportFragment renders the elements of its ObjectAdapter as a set of rows in a vertical list.The Adapter's PresenterSelector must maintain subclasses of RowPresenter.

When FullWidthDetailsOverviewRowPresenter is found in adapter, DetailsSupportFragment will setup default behavior of the DetailsOverviewRow:

The recommended activity themes to use with a DetailsSupportFragment are

DetailsSupportFragment can use DetailsSupportFragmentBackgroundController to add a parallax drawable background and embedded video playing fragment.

public RowsSupportFragment getRowsSupportFragment()

Embedded RowsSupportFragment showing multiple rows for DetailsSupportFragment.

onCreate

public void onCreate(Bundle savedInstanceState)

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
Bundle savedInstanceState

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

onCreateView

public @Nullable View onCreateView(
    @NonNull LayoutInflater inflater,
    @Nullable ViewGroup container,
    @Nullable 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,

@Nullable 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.

@Nullable Bundle savedInstanceState

If non-null, this fragment is being re-constructed from a previous saved state as given here.

Returns
@Nullable View

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

onDestroyView

public void onDestroyView()

Called when the view previously created by onCreateView has been detached from the fragment. The next time the fragment needs to be displayed, a new view will be created. This is called after onStop and before onDestroy. It is called regardless of whether onCreateView returned a non-null view. Internally it is called after the view's state has been saved but before it has been removed from its parent.

onInflateTitleView

public @NonNull View onInflateTitleView(
    @NonNull LayoutInflater inflater,
    @Nullable ViewGroup parent,
    @Nullable Bundle savedInstanceState
)

Called by installTitleView to inflate title view. Default implementation uses layout file lb_browse_title. Subclass may override and use its own layout, the layout must have a descendant with id browse_title_group that implements TitleViewAdapter.Provider. Subclass may return null if no title is needed.

Parameters
@NonNull LayoutInflater inflater

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

@Nullable ViewGroup parent

Parent of title view.

@Nullable Bundle savedInstanceState

If non-null, this fragment is being re-constructed from a previous saved state as given here.

Returns
@NonNull View

Title view which must have a descendant with id browse_title_group that implements TitleViewAdapter.Provider, or null for no title view.

onStart

public void onStart()

Called when the Fragment is visible to the user. This is generally tied to Activity.onStart of the containing Activity's lifecycle.

onStop

public void onStop()

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

setAdapter

Added in 1.1.0
public void setAdapter(ObjectAdapter adapter)

Sets the list of rows for the fragment.

setOnItemViewClickedListener

Added in 1.1.0
