title: How to get all checked items from a ListView?
body: <p>I've a couple of question I haven't been able to figure out.</p>
  
  <p>I'm trying to get all the checked elements from a <code>ListView</code> but:</p>
  
  <ol>
  <li><p>If I check and then uncheck an element, it's returned as "checked" by the <code>getCheckedItemPositions()</code> function</p></li>
  <li><p>I don't know how can I iterate through this: </p>
  
  <pre><code>SparseBooleanArray checked = list.getCheckedItemPositions();
  </code></pre></li>
  </ol>
