我们可以隐藏mapview但不能隐藏在Android中的谷歌地图上吗？

Question

我想通过隐藏地图在谷歌地图上显示点。这可能吗？

我的代码是

public class SampleGeoPointsActivity extends MapActivity {
private MapView gMapView;
//private MapController mc;
//double lat=43.467604;
//double lng=-3.833841;
@Override
public void onCreate(Bundle savedInstanceState) {
// Creating and initializing Map
     super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
try{
    gMapView = (MapView) findViewById(R.id.myGMap);
    gMapView.setBuiltInZoomControls(true);
    //gMapView.setVisibility(MapView.INVISIBLE);
    List<Overlay> mapOverlays = gMapView.getOverlays();
    //gMapView.getOverlays().subList(0, 0);
    Drawable drawable = this.getResources().getDrawable(R.drawable.androidmarker);
    HelloItemizedOverlay itemizedoverlay = new HelloItemizedOverlay(drawable, this);
    GeoPoint point = new GeoPoint(35410000, 139460000);
    OverlayItem overlayitem = new OverlayItem(point, "Hello", "I'm in japan City!");
    GeoPoint point1 = new GeoPoint(19240000,-99120000);
    OverlayItem overlayitem1 = new OverlayItem(point1, "Hello", "I'm in Mexico City!");
    overlayitem.setMarker(drawable);
    itemizedoverlay.addOverlay(overlayitem);
    itemizedoverlay.addOverlay(overlayitem1);
    mapOverlays.add(itemizedoverlay);
    gMapView.setVisibility(1);
    gMapView.invalidate();

    }catch(Exception e)
    {
        Log.d("Exception","Error Message"+e.getMessage());
    }
}
@Override
protected boolean isRouteDisplayed() {
    return false;
} }

是否可以隐藏地图视图并仅显示Google地图中的叠加层？
