title: Android Spinner: Get the selected item change event
body: <p>How can you set the event listener for a Spinner when the selected item changes?</p>
  
  <p>Basically what I am trying to do is something similar to this:</p>
  
  <pre><code>spinner1.onSelectionChange = handleSelectionChange;
  
  void handleSelectionChange(Object sender){
      //handle event
  }
  </code></pre>
