title: How to display balloon on the MapView, once map is shown?
body: <p>I use <a href="https://github.com/donnfelker/android-mapviewballoons" rel="nofollow">android-mapviewballoons</a> library to show balloons.
  So, once user clicks on my marker, balloon is shown.</p>
  
  <p>The question I have: how to display the balloon for particular item without waiting for user click?</p>
  
  <p><strong>Upd.</strong> how to identify i?
  Currently I have the following:</p>
  
  <pre><code>public class Map extends MapActivity {
      public void onCreate(Bundle savedInstanceState) {
          // here I have extras.getDouble("lat") and extras.getDouble("lng") - 
          // the location balloon should be shown for
          ...
          itemizedOverlay = new MapOverlay(drawable, mapView);
          for (int i = 0; i &lt; items.getCount(); i++) {
             // here I add markers, one of them will have lat and lng equal to 
             // the values passed in extras
  
      public class MapOverlay extends BalloonItemizedOverlay&lt;OverlayItem&gt; {
          ...
          protected OverlayItem createItem(int i) {
  </code></pre>
  
  <p>Also, with regards to the following code:</p>
  
  <pre><code>//  BalloonOverlayView is a raw type. References to generic type BalloonOverlayView&lt;Item&gt; should be parameterized
  BalloonOverlayView bov = new BalloonOverlayView(context, 50);
  // What is item there? should be getItem(i)?
  bov.setData(item);
  // The method setPosition(int) is undefined for the type BalloonOverlayView
  BalloonOverlayView.setPosition(i);
  </code></pre>
