ListActivity with selectable Items
<p>To improve usability for blind users, I need a ListActivity with an OnItemSelected method to add stuff like vibration or sounds when a specific listitem is selected. 
Therefore I have extended the ListActivity class and added the following methods:</p>

<pre><code>protected void onListItemSelected(ListView parent, View v, int position, long id) {
}

private AdapterView.OnItemSelectedListener mOnSelectedListener = new AdapterView.OnItemSelectedListener() {

    public void onItemSelected(AdapterView&lt;?&gt; parent, View v, int position, long id) {
        onListItemSelected((ListView)parent, v, position, id);          
    }

    public void onNothingSelected(AdapterView&lt;?&gt; parent) {
        // TODO Auto-generated method stub          
    }
};
</code></pre>

<p>Now, when I create an instance of my new Class SelectableListActivity and override the onListItemSelected method, still nothing happens. Any Ideas? Many thanks in advance!  </p>
