title: Android:Fragment in NavigationDrawer
body: <p>I have a strange problem I created a navigation drawer and a fragment.
  when I insert a list view in the fragment it appears normally but if I remove that list view and insert anything else like text view or image view nothing appears in the fragment when I tap its item in the navigation drawer.</p>
  
  <p>Note: I know that the list view need to be initialized in the java file too and I did that. is the text view or image view needs something like that? may be the error here... any help please....</p>
  
  <pre><code>public void onActivityCreated(Bundle savedInstanceState){
      super.onActivityCreated(savedInstanceState);
      List&lt;String&gt; content = new ArrayList&lt;&gt;();
      content.add("list");
      content.add("list");
      content.add("list");
      content.add("list");
      content.add("list");
      content.add("list");
      content.add("list");
      ListView listView = (ListView) getActivity().findViewById(R.id.listView);
      listView.setAdapter(new ArrayAdapter&lt;&gt;(getActivity(), android.R.layout.simple_list_item_1, content));
  }
