On the map you can add references with addMarker, addCircle, addPolyline and addPolygon.
In the link image was probably used addPolygon.
It also has addGroundOverlay, as well as Circle a Polyline and Polygon the Ground accompanies the rotation and tilt zoom of the map.
In the example I drew a star-shaped png 256x256. See the result:
@Override
public void onMapReady(GoogleMap map)
{
GroundOverlayOptions options = new GroundOverlayOptions();
LatLng latLng = new LatLng("lat","lng"); // posição que deseja adicionar a marca
options.position(latLng,400,400); // 400 - raio em metros
options.image(BitmapDescriptorFactory.fromResource(R.drawable.ground));
options.clickable(false);
map.addGroundOverlay(options);
}
beauty! But when you ask a question, try to be very clear. If you had inserted that image of your comment here in your question, I wouldn’t have even added the answer. Good luck!
