RowsSupportFragment

Added in 1.1.0

Kotlin |Java

public class RowsSupportFragment extends Fragment implements BrowseSupportFragment.MainFragmentRowsAdapterProvider, BrowseSupportFragment.MainFragmentAdapterProvider

java.lang.Object
↳	androidx.fragment.app.Fragment
	↳	androidx.leanback.app.RowsSupportFragment

An ordered set of rows of leanback widgets.

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

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.

onSaveInstanceState

public void onSaveInstanceState(Bundle outState)

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
`Bundle outState`	Bundle in which to place your saved state.

onTransitionEnd

Added in 1.1.0

public void onTransitionEnd()

onTransitionPrepare

Added in 1.1.0

public boolean onTransitionPrepare()

onTransitionStart

Added in 1.1.0

public void onTransitionStart()

onViewCreated

public void onViewCreated(@NonNull View view, @Nullable 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`.
`@Nullable Bundle savedInstanceState`	If non-null, this fragment is being re-constructed from a previous saved state as given here.

Added in 1.1.0

public final void setAdapter(ObjectAdapter rowsAdapter)

Sets the adapter that represents a list of rows.

Parameters
`ObjectAdapter rowsAdapter`	Adapter that represents list of rows.

setAlignment

Added in 1.1.0

public void setAlignment(int windowAlignOffsetFromTop)

setEntranceTransitionState

Added in 1.1.0

public void setEntranceTransitionState(boolean afterTransition)

For rows that willing to participate entrance transition, this function hide views if afterTransition is true, show views if afterTransition is false.

setExpand

Added in 1.1.0

public void setExpand(boolean expand)

Set the visibility of titles/hovercard of browse rows.

Added in 1.1.0

public void setOnItemViewClickedListener(BaseOnItemViewClickedListener listener)

Sets an item clicked listener on the fragment. OnItemViewClickedListener will override View.OnClickListener that item presenter sets during onCreateViewHolder. So in general, developer should choose one of the listeners but not both.

Added in 1.1.0

public void setOnItemViewSelectedListener(BaseOnItemViewSelectedListener listener)

Sets an item selection listener.

Added in 1.1.0

public final void setPresenterSelector(PresenterSelector presenterSelector)

Set the presenter selector used to create and bind views.

setSelectedPosition

Added in 1.1.0

public void setSelectedPosition(int position)

Sets the selected row position with smooth animation.

setSelectedPosition

Added in 1.1.0

public void setSelectedPosition(int position, boolean smooth)

Sets the selected row position.

Added in 1.1.0

public void setSelectedPosition(
    int rowPosition,
    boolean smooth,
    Presenter.ViewHolderTask rowHolderTask
)

Selects a Row and perform an optional task on the Row. For example setSelectedPosition(10, true, new ListRowPresenterSelectItemViewHolderTask(5)) Scroll to 11th row and selects 6th item on that row. The method will be ignored if RowsSupportFragment has not been created (i.e. before onCreateView).

Parameters
`int rowPosition`	Which row to select.
`boolean smooth`	True to scroll to the row, false for no animation.
`Presenter.ViewHolderTask rowHolderTask`	Task to perform on the Row.
