SearchSupportFragment

extends Fragment

java.lang.Object
↳	android.support.v4.app.Fragment
	↳	android.support.v17.leanback.app.SearchSupportFragment

Class Overview

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

If you do not supply a callback via setSpeechRecognitionCallback(SpeechRecognitionCallback), an internal speech recognizer will be used for which your application will need to request android.permission.RECORD_AUDIO.

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().

Public Constructors

public SearchSupportFragment ()

Public Methods

public static Bundle createArgs (Bundle args, String query, String title)

public static Bundle createArgs (Bundle args, String query)

Parameters

args	Bundle to use for the arguments, if null a new Bundle will be created.

public void displayCompletions (List<String> completions)

Display the completions shown by the IME. An application may provide a list of query completions that the system will show in the IME.

Parameters

completions	A list of completions to show in the IME. Setting to null or empty will clear the list.

public Drawable getBadgeDrawable ()

Returns the badge drawable in the search bar.

public Intent getRecognizerIntent ()

Returns an intent that can be used to request speech recognition. Built from the base ACTION_RECOGNIZE_SPEECH plus extras:

EXTRA_LANGUAGE_MODEL set to LANGUAGE_MODEL_FREE_FORM
EXTRA_PARTIAL_RESULTS set to true
EXTRA_PROMPT set to the search bar hint text

For handling the intent returned from the service, see setSearchQuery(Intent, boolean).

public String getTitle ()

Returns the title set in the search bar.

public static SearchSupportFragment newInstance (String query)

Create a search fragment with a given search query.

You should only use this if you need to start the search fragment with a pre-filled query.

Parameters

query	The search query to begin with.

Returns

A new SearchSupportFragment.

public void onCreate (Bundle savedInstanceState)

Called to do initial creation of a fragment. This is called after onAttach(Activity) and before onCreateView(LayoutInflater, ViewGroup, Bundle).

Note that this can be called while the fragment's activity is still in the process of being created. As such, you can not rely on things like the activity's content view hierarchy being initialized at this point. If you want to do work once the activity itself is created, see onActivityCreated(Bundle).

Parameters

savedInstanceState	If the fragment is being re-created from a previous saved state, this is the state.

public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)

Called to have the fragment instantiate its user interface view. This is optional, and non-graphical fragments can return null (which is the default implementation). This will be called between onCreate(Bundle) and onActivityCreated(Bundle).

If you return a View from here, you will later be called in onDestroyView() when the view is being released.

Parameters

inflater	The LayoutInflater object that can be used to inflate any views in the fragment,
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.
savedInstanceState	If non-null, this fragment is being re-constructed from a previous saved state as given here.

Returns

Return the View for the fragment's UI, or null.

public void onDestroy ()

Called when the fragment is no longer in use. This is called after onStop() and before onDetach().

public void onPause ()

Called when the Fragment is no longer resumed. This is generally tied to Activity.onPause of the containing Activity's lifecycle.

public void onResume ()

Called when the fragment is visible to the user and actively running. This is generally tied to Activity.onResume of the containing Activity's lifecycle.

public void onStart ()

Called when the Fragment is visible to the user. This is generally tied to Activity.onStart of the containing Activity's lifecycle.

public void setBadgeDrawable (Drawable drawable)

Sets the badge drawable that will be shown inside the search bar next to the title.

public void setOnItemClickedListener (OnItemClickedListener listener)

This method is deprecated.
Use setOnItemViewClickedListener(OnItemViewClickedListener)

Sets an item clicked listener for the results.

Parameters

listener	The item clicked listener to be invoked when an item in the search results is clicked.

public void setOnItemSelectedListener (OnItemSelectedListener listener)

This method is deprecated.
Use setOnItemViewSelectedListener(OnItemViewSelectedListener)

Sets an item selection listener for the results.

Parameters

listener	The item selection listener to be invoked when an item in the search results is selected.

public void setOnItemViewClickedListener (OnItemViewClickedListener listener)

Sets an item clicked listener for the results.

Parameters

listener	The item clicked listener to be invoked when an item in the search results is clicked.

public void setOnItemViewSelectedListener (OnItemViewSelectedListener listener)

Sets an item selection listener for the results.

Parameters

listener	The item selection listener to be invoked when an item in the search results is selected.

public void setSearchQuery (Intent intent, boolean submit)

Sets the text of the search query based on the EXTRA_RESULTS in the given intent, and optionally submit the query. If more than one result is present in the results list, the first will be used.

Parameters

intent	Intent received from a speech recognition service.
submit	Whether to submit the query.

public void setSearchQuery (String query, boolean submit)

Sets the text of the search query and optionally submits the query. Either onQueryTextChange or onQueryTextSubmit will be called on the provider if it is set.

Parameters

query	The search query to set.
submit	Whether to submit the query.

public void setSearchResultProvider (SearchSupportFragment.SearchResultProvider searchResultProvider)

Set the search provider that is responsible for returning results for the search query.

public void setSpeechRecognitionCallback (SpeechRecognitionCallback callback)

Set this callback to have the fragment pass speech recognition requests to the activity rather than using an internal recognizer.

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".

public void startRecognition ()

Starts speech recognition. Typical use case is that activity receives onNewIntent() call when user clicks a MIC button. Note that SearchSupportFragment automatically starts speech recognition at first time created, there is no need to call startRecognition() when fragment is created.
