title: Android ListPreference with add-button
body: <p>Is there an example or maybe an already implemented ListPreference for Android, which has a TextView and a Button to add a new value to the list?</p>
  
  <p>Something like this:</p>
  
  <p>|------------------------| |Add|</p>
  
  <ul>
  <li>item</li>
  <li>item</li>
  <li>item</li>
  </ul>
