Question

I have the following code, but the overlay doesn’t seem to be visible on the map, although the focus is on the desired geo points.
Here’s the code:

   public void setOverlay()
{
    MapView mapView = (MapView)findViewById(R.id.mapview);
    mapView.getController().setCenter(place.getGeoPoint());
    List<Overlay> mapOverlays = mapView.getOverlays();
    Drawable drawable = this.getResources().getDrawable(R.drawable.ic_launcher);
    MyItemizedOverlay itemizedOverlay = new MyItemizedOverlay(drawable);
    OverlayItem overlayitem = new OverlayItem(place.getGeoPoint(), "Hola, Mundo!", "I'm in Mexico City!");
    itemizedOverlay.addOverlay(overlayitem);
    mapOverlays.add(itemizedOverlay);


}

What could be the problem here?

Answer 1

You need to call:

mapView.invalidate();

To force the redraw of overlays after you add them to MapView. Add the line above to the bottom of your method and it should work (I´m assuming that your icon is not fully transparent :-), in that case you will not see it in anyway)
