title: DialogFragment wrap_content without title
body: <p>I want to show my dialogFragment without a title. </p>
  
  <p>I start my dialog like this: </p>
  
  <pre><code>MyDialogFragment dialog = new MyDialogFragment();
  dialog.show(getFragmentManager(), "dialog");
  </code></pre>
  
  <p>This works fine, but I have a title in my dialog.</p>
  
  <p>For removing the title I tried to do this in my OnCreateView:</p>
  
  <pre><code>getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
  </code></pre>
  
  <p>and this in my onCreate:</p>
  
  <pre><code>Dialog dialog = super.onCreateDialog(savedInstanceState);
  dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
  </code></pre>
  
  <p>and this also in onCreateView and onCreate:</p>
  
  <pre><code>setStyle(DialogFragment.STYLE_NO_TITLE, 0);
  </code></pre>
  
  <p>But every time my window is a small, white dialog. My View is not visible, I think, it's because my dialog is too small. I found some helps, where I can set my Dialogs size, but I don't want to set a fix size. My dialog should has the size, which is really necessary to show my full view. </p>
  
  <p>How can I set my dialogs size as necessary?</p>
  
  <p>Or is there a solution with a alertDialog, where I can set my customView or something like this?</p>
  
  <p>Thanks a lot for help! :)</p>
