Android Fragments Content View aún no creado

Todo funcionaba bien. Pero después de algunas pruebas a través de mi aplicación. Se bloquea y en mi Logcat veo esta "Vista de contenido aún no creado" Después de algunos google, descubrí que debería poner mi listadapter en onActivityCreated. Mis códigos son un poco diferentes, estoy usando un lazyadapter así que creo que necesito algunos consejos. Por favor, ayúdame.

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) { } }
