title: Is there ever a good reason to use the Child Fragment Manager for DialogFragments?
body: <p>Normally when showing a DialogFragment from an Activity, you do this:</p>
  
  <pre><code>MyDialogFragment myDialogFragment = MyDialogFragment.newInstance(args);             
  myDialogFragment.show(getSupportFragmentManager(), MY_TAG);
  </code></pre>
  
  <p>Or if you are in a Fragment, you can do this:</p>
  
  <pre><code>MyDialogFragment myDialogFragment = MyDialogFragment.newInstance(args);             
  myDialogFragment.show(getActivity().getSupportFragmentManager(), MY_TAG);
  </code></pre>
  
  <p>Which as far as I can tell is pretty similar to the first since it's finding the Activity and then calling from it.</p>
  
  <p>However, again, assuming we're in a Fragment, would it ever make sense to launch a DialogFragment by doing this instead:</p>
  
  <pre><code>MyDialogFragment myDialogFragment = MyDialogFragment.newInstance(args);             
  myDialogFragment.show(getChildFragmentManager(), MY_TAG);
  </code></pre>
  
  <p>Would the calling Fragment be considered the parent of the DialogFragment?</p>
