title: clearFocus() on empty editText is not working in Android
body: <p>I tried to remove focus from empty editText but it isn't working correctly.
  I called <code>clearFocus()</code> on <code>edittext</code> ,and then I placed break point at my <code>onFocusChanged()</code> function call.</p>
  
  <p>Here is what happened:
  <code>onFocusChanged()</code> called 4 times with the focused parameters values <code>false,true,false,true</code>.</p>
  
  <p>What I thought was that <code>onFocusChanged()</code> must be called only once (with focused = false)</p>
  
  <p>Sorry for my bad English. Any help would be appreciated.
  Thanks</p>
