title: ProgressDialog as drawable ? GIF or something?
body: <p>I'm making a sign up activity, where i use drawables resources to interact. TextWatcher and some coding, then (example):</p>
  
  <pre><code>etPass.setCompoundDrawablesWithIntrinsicBounds(R.drawable.icon_lock_open, 0, R.drawable.icon_close, 0);
  </code></pre>
  
  <p>Now, i made a task to check e-mail on database. I would like to show a ProgressDialog while this task gets the result. I tried with a gif, but it doesn't animate properly. I want something like:</p>
  
  <p><a href="https://i.stack.imgur.com/Yftmd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Yftmd.png" alt=""></a></p>
  
  <p><strong>Note</strong>: I would like to do this through "setCompoundDrawablesWithIntrinsicBounds", once it already comes formatted and fit on the field. But i'm open to other ways.</p>
  
  <p>Thanks !</p>
