title: How to get obj key from FirebaseListAdapter on Item Click. FirebaseUI
body: <p>When subclassing FirebaseListAdapter in FirebaseUI how can one get the obj key of the item clicked?</p>
  
  <p>FirebaseListAdapter has the following method which gets itemId, but returns long. But I require the object key which is in the default string format.</p>
  
  <pre><code>public long getItemId(int i) {
      return (long)this.mSnapshots.getItem(i).getKey().hashCode();
  }
  </code></pre>
