title: Different named Markers on Google Android Map
body: <p>i want to add many different markers on an android map. My code works good so far with the same overlay over and over again:</p>
  
  <pre><code>mapOverlays = mapView.getOverlays();
  drawable = this.getResources().getDrawable(R.drawable.marker);
  itemizedOverlay = new MyItemizedOverlay(drawable);
  OverlayItem overlayItem = new OverlayItem(geoPoint, "foo", "bar");
  mapOverlays.add(itemizedOverlay);
  </code></pre>
  
  <p>This works fine so far. But every marker is the same. What I want to do now is having different markers on the map like the ones you see on Google Maps Webapp (a marker named "A", the next one "B", and so on).
  How can I achieve this? Do I have to add an extra png marker file to my app ? (marker_a.png, marker_b.png,...) or is there a simpler way to achieve this? It could also be that there will be more than 26 results so that i possibly need different colours of the markers. </p>
