Overlay Classes
Overlay Classes
Any overlay you want to add to your map needs to be implemented as a subclass of Overlay. There is an ItemizedOverlay subclass available if you are looking to add push-pins or the like; ItemizedOverlay simplifies this process.
To attach an overlay class to your map, just call getOverlays() on your MapView and add() your Overlay instance to it:
marker.setBounds(0, 0, marker.getIntrinsicWidth(),
marker.getIntrinsicHeight());
map.getOverlays().add(new SitesOverlay(marker));
We will explain that marker in just a bit.
