title: How to expand setOnMarkerClickListener of OSMbonuspacket Marker without overriding default behavior?
body: <p>I am working on an app that makes use of the <strong>OSMbonuspacket</strong>. I added markers with descriptions to the map. When clicking one of the markers, the description box is shown. </p>
  
  <p>Now I want to call another function when tapping on a marker. Let's say I want to show a Toast. So I added the following <code>setOnMarkerClickListener()</code> function:</p>
  
  <pre><code>marker.setOnMarkerClickListener(new Marker.OnMarkerClickListener() {
      @Override
      public boolean onMarkerClick(Marker marker, MapView mapView) {
          Toast.makeText(context, "Hallo", Toast.LENGTH_LONG).show();
          return false;
      }
  });
  </code></pre>
  
  <p>This shows the Toast when clicking the marker. However, the description box is not displayed anymore. I guess that I am overriding the default behavior.  with this function. I made an app with a Google Maps integration once and did the same thing without any problems.</p>
  
  <p>Does anyone know how to accomplish this with the OSMbonuspacket?</p>
