In that case, what I would probably do is derive a class from
MyLocationOverlay, as you already mentioned, and override the onTap function
(not dispatchTap). I believe this is called whenever the map view is pressed
anywhere, but then only returns true if the given overlay was actually
tapped (to prevent dispatching the event to the other overlays).
So simply:
public boolean onTap(GeoPoint gp, MapView mv)
{
// Do what you need with current accuracy and location
return super.onTap(gp, mv);
}
Hope that helps.
