title: How to display an existing ListFragment in a DialogFragment
body: <p>I have the following problem:</p>
  
  <p>I have an exisiting <code>ListFragment</code>, but I would like to display this as a dialog.</p>
  
  <p>My first approach was to create a <code>DialogFragment</code> which has to <code>ListFragment</code> inside of it, but appearently it is currently not possible to put fragments in fragments.</p>
  
  <p>Extending <code>DialogFragment</code> instead of <code>ListFragment</code> is also not possible, because of the heavy use of <code>ListFragment</code> methods.</p>
  
  <p>Is there an easy way to do this?</p>
