MapFragment | Google Play services

A Map component in an app. This fragment is the simplest way to place a map in an application. It's a wrapper around a view of a map to automatically handle the necessary life cycle needs. Being a fragment, this component can be added to an activity's layout file simply with the XML below.

 <fragment
    class="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

GoogleMap

must be acquired using

getMapAsync(OnMapReadyCallback)

. This class automatically initializes the maps system and the view.

A view can be removed when the MapFragment's onDestroyView() method is called and the GoogleMapOptions.useViewLifecycleInFragment(boolean) option is set. When this happens the MapFragment is no longer valid until the view is recreated again later when the MapFragment's onCreateView(LayoutInflater, ViewGroup, Bundle) method is called.

Any objects obtained from the GoogleMap are associated with the view. It's important to not hold on to objects (e.g. Marker) beyond the view's life. Otherwise it will cause a memory leak as the view cannot be released.

Use this class only if you are targeting API 12 and above. Otherwise, use SupportMapFragment by adding the Android support library to your build path.

Public Constructors public MapFragment ()

Creates a map fragment. This constructor is public only for use by an inflater. Use newInstance() to create a MapFragment programmatically.

Public Methods public void getMapAsync (OnMapReadyCallback callback)

Sets a callback object which will be triggered when the GoogleMap instance is ready to be used.

Note that:

This method must be called from the main thread.
The callback will be executed in the main thread.
In the case where Google Play services is not installed on the user's device, the callback will not be triggered until the user installs it.
In the rare case where the GoogleMap is destroyed immediately after creation, the callback is not triggered.
The GoogleMap object provided by the callback is non-null.

Parameters callback The callback object that will be triggered when the map is ready to be used. Must not be null. public static MapFragment newInstance (GoogleMapOptions options)

Creates a map fragment with the given options.

Parameters options configuration GoogleMapOptions for a GoogleMap, or null to use the default options. public static MapFragment newInstance ()

Creates a map fragment, using default options.

public void onActivityCreated (Bundle savedInstanceState) public void onAttach (Activity activity) public void onCreate (Bundle savedInstanceState) public void onDestroyView () public final void onEnterAmbient (Bundle ambientDetails)

You must call this method from the parent WearableActivity's corresponding method.

public final void onExitAmbient ()

You must call this method from the parent WearableActivity's corresponding method.

public void onInflate (Activity activity, AttributeSet attrs, Bundle savedInstanceState)

Parse attributes during inflation from a view hierarchy into the arguments we handle.

public void onLowMemory () public void onSaveInstanceState (Bundle outState)

Provides a Bundle to store the state of the Fragment before it gets destroyed. It can later be retrieved when onCreate(Bundle) is called again.

public void setArguments (Bundle args)
