title: How to draw a Polygon on MapView, fill it, and put a onTouch Event on it
body: <p>Is it possible to set an EventListener in a drawn Polygon in a osmdroid MapView Overlay ? I would like to print on a Overlay and after touching it I would like to change its color or handle data behind a Polygon. </p>
  
  <p>For Example:</p>
  
  <p>Poly1: ID = 1337, P1(0,0),P2(1,0),......,Pn(0,0)</p>
  
  <p>Poly2: ID = 42 , P1(10,7),P2(18,39),......,Pn(10,7)</p>
  
  <p>After touching in Poly1 I want to know aha ID 1337 is pressed. An want to change its color.</p>
  
  <p>How could I implement such a behavior ? </p>
