Android Google Maps API v2 for Android MapView: embedding a GoogleMap in an existing layout
Example
It is possible to treat a GoogleMap as an Android view if we make use of the provided MapView class. Its usage is very similar to MapFragment.
In your layout use MapView as follows:
<com.google.android.gms.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
<!--
map:mapType="0" Specifies a change to the initial map type
map:zOrderOnTop="true" Control whether the map view's surface is placed on top of its window
map:useVieLifecycle="true" When using a MapFragment, this flag specifies whether the lifecycle of the map should be tied to the fragment's view or the fragment itself
map:uiCompass="true" Enables or disables the compass
map:uiRotateGestures="true" Sets the preference for whether rotate gestures should be enabled or disabled
map:uiScrollGestures="true" Sets the preference for whether scroll gestures should be enabled or disabled
map:uiTiltGestures="true" Sets the preference for whether tilt gestures should be enabled or disabled
map:uiZoomGestures="true" Sets the preference for whether zoom gestures should be enabled or disabled
map:uiZoomControls="true" Enables or disables the zoom controls
map:liteMode="true" Specifies whether the map should be created in lite mode
map:uiMapToolbar="true" Specifies whether the mapToolbar should be enabled
map:ambientEnabled="true" Specifies whether ambient-mode styling should be enabled
map:cameraMinZoomPreference="0.0" Specifies a preferred lower bound for camera zoom
map:cameraMaxZoomPreference="1.0" Specifies a preferred upper bound for camera zoom -->
/>
Your activity needs to implement the OnMapReadyCallback interface in order to work:
/**
* This shows how to create a simple activity with a raw MapView and add a marker to it. This
* requires forwarding all the important lifecycle methods onto MapView.
*/
public class RawMapViewDemoActivity extends AppCompatActivity implements OnMapReadyCallback {
private MapView mMapView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.raw_mapview_demo);
mMapView = (MapView) findViewById(R.id.map);
mMapView.onCreate(savedInstanceState);
mMapView.getMapAsync(this);
}
@Override
protected void onResume() {
super.onResume();
mMapView.onResume();
}
@Override
public void onMapReady(GoogleMap map) {
map.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}
@Override
protected void onPause() {
mMapView.onPause();
super.onPause();
}
@Override
protected void onDestroy() {
mMapView.onDestroy();
super.onDestroy();
}
@Override
public void onLowMemory() {
super.onLowMemory();
mMapView.onLowMemory();
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mMapView.onSaveInstanceState(outState);
}
}
