title: DialogFragment onCreateDialog()
body: <p>My app crashes when I add the onCreateDialog Method to the DialogFragment class. If I don't add that method, it shows the dialog which has a list. I went through other similar topics but it din't solve my problem. Please, I could use some assistance here. Here's my code.</p>
  
  <pre><code>public class SubVitalsEntryDialogFragment extends DialogFragment {
  
      ArrayList&lt;SubVitals&gt; subVitalList = new ArrayList&lt;SubVitals&gt;();
      ListView mylist;
  
      public static SubVitalsEntryDialogFragment newInstance(ArrayList&lt;SubVitals&gt; sub) {
          SubVitalsEntryDialogFragment f = new SubVitalsEntryDialogFragment();
  
          // Supply num input as an argument.
          Bundle args = new Bundle();
          args.putParcelableArrayList("subVitalList", sub);
          f.setArguments(args);
          return f;
      }
  
      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container,
                               Bundle savedInstanceState) {
  
          View view = inflater.inflate(R.layout.subvitals_dialog_layout, null, false);
          mylist = (ListView) view.findViewById(R.id.vitalEntryListView);
          getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
          return view;
      }
  
      @Override
      public void onActivityCreated(Bundle savedInstanceState) {
  
          super.onActivityCreated(savedInstanceState);
          subVitalList = getArguments().getParcelableArrayList("subVitalList");
