class BrowseFragment : BaseFragment

kotlin.Any
↳	android.app.Fragment
	↳	androidx.leanback.app.BrandedFragment
		↳	androidx.leanback.app.BaseFragment
			↳	androidx.leanback.app.BrowseFragment

A fragment for creating Leanback browse screens. It is composed of a RowsFragment and a HeadersFragment.

A BrowseFragment renders the elements of its ObjectAdapter as a set of rows in a vertical list. The elements in this adapter must be subclasses of Row.

The HeadersFragment can be set to be either shown or hidden by default, or may be disabled entirely. See setHeadersState for details.

By default the BrowseFragment includes support for returning to the headers when the user presses Back. For Activities that customize onBackPressed, you must disable this default Back key support by calling setHeadersTransitionOnBackEnabled with false and use BrowseFragment.BrowseTransitionListener and startHeadersTransition.

The recommended theme to use with a BrowseFragment is Theme_Leanback_Browse.

Parameters
`color: @ColorInt Int`	The color to use as the brand color of the fragment.

setBrowseTransitionListener

Added in 1.1.0

NOTE: If an Activity has its own onBackPressed() handling, you must disable this feature. You may use startHeadersTransition and BrowseTransitionListener in your own back stack handling.

Added in 1.1.0

Deprecated in 1.1.0

fun setOnItemViewClickedListener(listener: OnItemViewClickedListener!): 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

Deprecated in 1.1.0

fun setOnItemViewSelectedListener(listener: OnItemViewSelectedListener!): Unit

Sets an item selection listener.

setSelectedPosition

Added in 1.1.0

setSelectedPosition

Added in 1.1.0

Deprecated in 1.1.0

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

Added in 1.1.0

Deprecated in 1.1.0

fun setSelectedPosition(

): Unit

Selects a Row and perform an optional task on the Row. For example setSelectedPosition(10, true, new ListRowPresenterSelectItemViewHolderTask(5)) scrolls to 11th row and selects 6th item on that row. The method will be ignored if RowsFragment 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!`	Optional task to perform on the Row. When the task is not null, headers fragment will be collapsed.

startHeadersTransition

Added in 1.1.0

Deprecated in 1.1.0

fun startHeadersTransition(withHeaders: Boolean): Unit

Starts a headers transition.

This method will begin a transition to either show or hide the headers, depending on the value of withHeaders. If headers are disabled for this browse fragment, this method will throw an exception.

Parameters
`withHeaders: Boolean`	True if the headers should transition to being shown, false if the transition should result in headers being hidden.
