RowsSupportFragment

Added in 1.1.0

Kotlin |Java

class RowsSupportFragment : Fragment, BrowseSupportFragment.MainFragmentRowsAdapterProvider, BrowseSupportFragment.MainFragmentAdapterProvider

kotlin.Any
↳	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.

Added in 1.1.0

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.

onDestroyView

fun onDestroyView(): Unit

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

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.

onTransitionEnd

Added in 1.1.0

fun onTransitionEnd(): Unit

onTransitionPrepare

Added in 1.1.0

fun onTransitionPrepare(): Boolean

onTransitionStart

Added in 1.1.0

fun onTransitionStart(): Unit

onViewCreated

fun onViewCreated(view: View, savedInstanceState: Bundle?): Unit

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

Added in 1.1.0

fun setAdapter(rowsAdapter: ObjectAdapter!): Unit

Sets the adapter that represents a list of rows.

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

setAlignment

Added in 1.1.0

fun setAlignment(windowAlignOffsetFromTop: Int): Unit

setEntranceTransitionState

Added in 1.1.0

fun setEntranceTransitionState(afterTransition: Boolean): Unit

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

fun setExpand(expand: Boolean): Unit

Set the visibility of titles/hovercard of browse rows.

Added in 1.1.0

fun setOnItemViewClickedListener(listener: BaseOnItemViewClickedListener!): Unit

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

fun setOnItemViewSelectedListener(listener: BaseOnItemViewSelectedListener!): Unit

Sets an item selection listener.

Added in 1.1.0

fun setPresenterSelector(presenterSelector: PresenterSelector!): Unit

Set the presenter selector used to create and bind views.

setSelectedPosition

Added in 1.1.0

fun setSelectedPosition(position: Int): Unit

Sets the selected row position with smooth animation.

setSelectedPosition

Added in 1.1.0

fun setSelectedPosition(position: Int, smooth: Boolean): Unit

Sets the selected row position.

Added in 1.1.0

fun setSelectedPosition(
    rowPosition: Int,
    smooth: Boolean,
    rowHolderTask: Presenter.ViewHolderTask!
): Unit

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
`rowPosition: Int`	Which row to select.
`smooth: Boolean`	True to scroll to the row, false for no animation.
`rowHolderTask: Presenter.ViewHolderTask!`	Task to perform on the Row.
