title: Create a progressDialog only with the spinner (in the middle)
body: <p>I need to create a progressDialog only with the spinner and without the box (or at least with a smaller box and the image in the middle).</p>
  
  <p>I don't want to add a spinner to my .xml (layout file) to load the spinner.</p>
  
  <p>Is there any way to accomplish this? Thanks!</p>
