Android MapView: incorporation d'un GoogleMap dans une mise en page existante


Exemple

Il est possible de traiter un GoogleMap comme une vue Android si nous utilisons la classe MapView fournie. Son utilisation est très similaire à MapFragment.

Dans votre mise en page, utilisez MapView comme suit:

<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 -->
    />

Votre activité doit implémenter l'interface OnMapReadyCallback pour fonctionner:

/**
* 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);
    }
}
