MapView

public class MapView extends FrameLayout

A View which displays a map (with data obtained from the Google Maps service). When focused, it will capture keypresses and touch gestures to move the map.

Users of this class must forward all the life cycle methods from the Activity or Fragment containing this view to the corresponding ones in this class. In particular, you must forward on the following methods:

A GoogleMap must be acquired using getMapAsync(OnMapReadyCallback). The MapView automatically initializes the maps system and the view.

For a simpler method of displaying a Map use MapFragment (or SupportMapFragment) if you are looking to target earlier platforms.

Note: You are advised not to add children to this view.

Public Methods

public void getMapAsync (OnMapReadyCallback callback)

Returns a non-null instance of the GoogleMap, 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.
  • 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.

public final void onCreate (Bundle savedInstanceState)

You must call this method from the parent Activity/Fragment's corresponding method.

public final void onDestroy ()

You must call this method from the parent Activity/Fragment's corresponding method.

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 final void onLowMemory ()

You must call this method from the parent Activity/Fragment's corresponding method.

public final void onPause ()

You must call this method from the parent Activity/Fragment's corresponding method.

public final void onResume ()

You must call this method from the parent Activity/Fragment's corresponding method.

public final void onSaveInstanceState (Bundle outState)

You must call this method from the parent Activity/Fragment's corresponding method.

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.

Note that storing custom Parcelable objects directly in the provided Bundle will throw a ClassNotFoundException. This is due to the fact that this Bundle is parceled (thus losing its attached ClassLoader) and unparceled later in a different ClassLoader.

A workaround to this issue is to store custom Parcelable objects in another Bundle object before putting them in the provided Bundle.

However, note that it is safe to store Parcelable objects from the Maps API (e.g. MarkerOptions, LatLng, etc.) directly in the provided Bundle.
