title: Android setChecked animation
body: <p>I have a problem on checkbox animation when <code>setChecked(true)</code>.
  Let me explain my condition.</p>
  
  <p>I have a <code>gridview</code> inside <code>viewpager</code> and one checkbox above the <code>viewpager</code>.
  I set an adapter to <code>gridview</code>. There are a checkbox and a icon in the adapter.</p>
  
  <p>When click an item, checkbox animation works fine. However, when try to select all items by one checkbox above the <code>viewpager</code>, all items are selected without checkbox animation, just can see only 2 views, checked box and unchecked box.</p>
  
  <p>Please help me out. Thanks.</p>
