Android片段内容视图尚未创建

一切都很顺利。但在通过我的应用程序进行一些测试之后。它崩溃了，在我的Logcat中，我看到了这个“内容视图还没有创建”在谷歌搜索之后，我发现我应该把我的listadapter放到onActivityCreated中。我的代码有点不同，我正在使用lazyadapter，所以我想我需要一些建议。请帮帮我

public class AndroidFragment extends SherlockListFragment  implements        ActionBar.TabListener{

            static final String URL = "https://xml.xml";
            static final String KEY_SONG = "song";
            static final String KEY_ID = "id";
            static final String KEY_TITLE = "title";
            static final String KEY_CAT_ARTIST = "artistcat";
            static final String KEY_DURATION = "duration";
            static final String KEY_THUMB_URL = "thumb_url";
            static final String KEY_BIG_URL = "big_url";
            static final String KEY_CAT_URL = "cat_url";
            static final String KEY_DESC = "cat_desc";
            ArrayList<HashMap<String, String>> menuItems;
            ListAdapter adapter;
            Context appContext;

            @Override
            public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
                appContext = inflater.getContext().getApplicationContext();

                new loadListView().execute();   



            return super.onCreateView(inflater, container, savedInstanceState);
            }


            public class loadListView extends AsyncTask<Integer, String, String> {

            @Override
            protected void onPreExecute() {
                    super.onPreExecute();
            }

            @Override
            protected String doInBackground(Integer... args) {
                // updating UI from Background Thread
            menuItems = new ArrayList<HashMap<String, String>>();


            XMLParser parser = new XMLParser();
            String xml = parser.getXmlFromUrl(URL); // getting XML
            Document doc = parser.getDomElement(xml); // getting DOM element

            NodeList nl = doc.getElementsByTagName(KEY_SONG);
            // looping through all item nodes <item>
            for (int i = 0; i < nl.getLength(); i++) {
            // creating new HashMap
            HashMap<String, String> map = new HashMap<String, String>();
            Element e = (Element) nl.item(i);
            // adding each child node to HashMap key => value
            map.put(KEY_ID, parser.getValue(e, KEY_ID));
            map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE));
            map.put(KEY_CAT_ARTIST, parser.getValue(e, KEY_CAT_ARTIST));
            map.put(KEY_DURATION, parser.getValue(e, KEY_DURATION));
            map.put(KEY_THUMB_URL, parser.getValue(e, KEY_THUMB_URL));
            map.put(KEY_BIG_URL, parser.getValue(e, KEY_BIG_URL));
            map.put(KEY_CAT_URL, parser.getValue(e, KEY_CAT_URL));
            map.put(KEY_DESC, parser.getValue(e, KEY_DESC));
            // adding HashList to ArrayList
            menuItems.add(map);
            }
            return null;
            }   


            @Override
            protected void onPostExecute(String args) {

            if (getActivity() != null) {
            adapter=new MainPageLazyAdapter(getActivity(), menuItems);
            setListAdapter(adapter);


            }

            }
            }


            @Override
            public void onTabSelected(Tab tab, FragmentTransaction ft) {
            ft.add(android.R.id.content, this);
            ft.attach(this);
            }

            @Override
            public void onTabUnselected(Tab tab, FragmentTransaction ft) {
            ft.detach(this);

            }

            @Override
            public void onTabReselected(Tab tab, FragmentTransaction ft) {
            }

        }

我想这应该能解决你的问题

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
   View view = inflater.inflate(R.layout.layout, null);
   return view  //You must return your view here
}

@Override
public void onResume() {
  //onResume happens after onStart and onActivityCreate
  new loadListView().execute();
  super.onResume() ; 
}

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
   View view = inflater.inflate(R.layout.layout, null);
   return view  //You must return your view here
}

@Override
public void onResume() {
  //onResume happens after onStart and onActivityCreate
  new loadListView().execute();
  super.onResume() ; 
}
