title: android:state_selected for ListView
body: <p>I have color state list resource which defines the listSelector for my ListView:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;selector xmlns:android="http://schemas.android.com/apk/res/android" &gt;
  
      &lt;item
          android:state_pressed="true"
          android:drawable="@drawable/listview_selector_pressed" /&gt;
  
      &lt;item
          android:state_focused="true"
          android:drawable="@drawable/listview_selector_focused" /&gt;
  
      &lt;item 
          android:state_selected="true"
          android:drawable="@drawable/listview_selector_selected" /&gt;
  
  &lt;/selector&gt;
  </code></pre>
  
  <p>Now, I know how to put a ListView item in the "pressed" and "focused" state, but I can't figure out what puts a ListView item in the "selected" state. ListView::getSelectedItem always returns null.</p>
  
  <p>I'm running in the emulator but thoughts on how to trigger this "selected" state on a device are also welcome.  </p>
