title: Activity Dialog unwanted padding
body: <p>I have made a <code>custom dialog</code> using an <code>Acitvity</code>.
  All works correct but when showing it, I can see a small top and right padding, you will see it on image, the <code>top padding</code> is undetectable because all background is black.</p>
  
  <p><img src="https://i.stack.imgur.com/VZ3i9.jpg" alt="enter image description here"></p>
  
  <p>You can see the error on top line and bottom button. All the <code>paddings</code> and <code>margins</code> have been set to 0dp, <code>layout</code> its set to <code>wrap content</code> and the inside elements with <code>match_parent</code>.</p>
  
  <p>It's not a big mistake but I would like to fix it.
  Thanks!</p>
  
  <p><strong>EDIT</strong>: In VM with android 2.2 it seems to run without <code>padding</code>, the image is VM 4.0 and i try with 2.3 device, both with that same problem.</p>
