public class BrowseSupportFragment
extends BaseSupportFragment


A fragment for creating Leanback browse screens. It is composed of a RowsSupportFragment and a HeadersSupportFragment.

A BrowseSupportFragment 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 HeadersSupportFragment can be set to be either shown or hidden by default, or may be disabled entirely. See setHeadersState(int) for details.

By default the BrowseSupportFragment 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(boolean) with false and use BrowseSupportFragment.BrowseTransitionListener and startHeadersTransition(boolean).

The recommended theme to use with a BrowseSupportFragment is Theme_Leanback_Browse.


Nested classes

class BrowseSupportFragment.BrowseTransitionListener

Listener for transitions between browse headers and rows. 

class BrowseSupportFragment.FragmentFactory<T extends Fragment>

Factory class responsible for creating fragment given the current item. 

interface BrowseSupportFragment.FragmentHost

Possible set of actions that BrowseSupportFragment exposes to clients. 

class BrowseSupportFragment.ListRowFragmentFactory

FragmentFactory implementation for ListRow

class BrowseSupportFragment.MainFragmentAdapter<T extends Fragment>

Interface that defines the interaction between BrowseSupportFragment and its main content fragment. 

interface BrowseSupportFragment.MainFragmentAdapterProvider

Interface to be implemented by all fragments for providing an instance of BrowseSupportFragment.MainFragmentAdapter

class BrowseSupportFragment.MainFragmentAdapterRegistry

Registry class maintaining the mapping of Row subclasses to BrowseSupportFragment.FragmentFactory

class BrowseSupportFragment.MainFragmentRowsAdapter<T extends Fragment>

This is used to pass information to RowsSupportFragment or its subclasses. 

interface BrowseSupportFragment.MainFragmentRowsAdapterProvider

Interface to be implemented by RowsSupportFragment and its subclasses for providing an instance of BrowseSupportFragment.MainFragmentRowsAdapter



The headers fragment is disabled and will never be shown.


The headers fragment is enabled and shown by default.


The headers fragment is enabled and hidden by default.
