public class SearchFragment extends Fragment

java.lang.Object
↳	android.app.Fragment
	↳	androidx.leanback.app.SearchFragment

A fragment to handle searches. An application will supply an implementation of the SearchResultProvider interface to handle the search and return an ObjectAdapter containing the results. The results are rendered into a RowsFragment, in the same way that they are in a .

A SpeechRecognizer object will be created for which your application will need to declare android.permission.RECORD_AUDIO in AndroidManifest file. If app's target version is >= 23 and the device version is >= 23, a permission dialog will show first time using speech recognition. 0 will be used as requestCode in requestPermissions() call. setSpeechRecognitionCallback is deprecated.

Speech recognition is automatically started when fragment is created, but not when fragment is restored from an instance state. Activity may manually call startRecognition, typically in onNewIntent().

setTitle

Added in 1.1.0

Deprecated in 1.1.0

public void setTitle(String title)

Sets the title string to be be shown in an empty search bar. The title may be placed in a call-to-action, such as "Search title" or "Speak to search title".

startRecognition

Added in 1.1.0
