title: Android: Spinning ProgressDialog - How?
body: <p>Using following code:</p>
  
  <pre><code>ProgressDialog pd = new ProgressDialog(activity);
  pd.setProgressStyle(ProgressDialog.STYLE_SPINNER);
  pd.show();
  </code></pre>
  
  <p>This shows spinning progress wheel, but it has a rectangle with white spaces on both sides.</p>
  
  <p>I only need the spinning wheel, nothing else. 
  And also possibly style it better.</p>
