title: One Drawable-XML-File for Parent and child
body: <p>I want to customize my PopUp-Window. PopUp-Window is an vertical LinearLayout with 3 TextViews.</p>
  
  <p>I want to have a border with Corners around the LinearLayout and smaller bottom borders at the TextViews. Is it possible to do that with one drawable-xml-file? Something like</p>
  
  <pre><code>&lt;item Android:id="@id/LinearLayout&gt;
  do borders and Corners for LL here
  &lt;/item&gt;
  &lt;item Android:id="@id/TextView1"&gt;
  do border Corner whatever for TextView1 here
  &lt;/item&gt;
  </code></pre>
  
  <p>And later adding to every Android:background the same XML-file..
  I know it doesn't work this way but maybe someone has an idea.</p>
