Android: forced mapview remapping

Question

I found that after changing the overlays on the MapView changes are not visible until the user moves the map, causing a redraw. Is there any way to make this redraw?

Answer 1

In your Overlay, keep a link to MapView. Then, when you want to force the redraw, call:

 mMapView.invalidate(); 

Alternatively, if you are not in the user interface thread, you can call this:

 mMapView.postInvalidate();
