title: What's the meaning of android:progressBarStyle attribute in ProgressBar?
body: <p>I've been looking through the documentation for <code>ProgressBar</code> class and found these attributes:</p>
  
  <ul>
  <li>android:progressBarStyle</li>
  <li>android:progressBarStyleHorizontal</li>
  <li>android:progressBarStyleLarge</li>
  <li>android:progressBarStyleSmall</li>
  </ul>
  
  <p>These four parameters are supposed to be a reference to some style as I take it. So the question is, what are these for? Style for the progress bar is set via android:style attribute and a reference to the global style attributes.</p>
  
  <p>Documentation doesn't say anything helpful, searched the Web, found nothing.</p>
