我对 SherlockListFtagment 和 xml 解析器有疑问。在 ListActivitiy 上使用 AsyncTask 并没有问题。在 ListFragment 上工作我需要编辑什么。

代码：

public class AndroidFragment extends SherlockListFragment{


    static final String URL = "http://...";
    // XML node keys
    static final String KEY_ITEM = "novost"; // parent node
    //static final String KEY_ID = "id";
    static final String KEY_NAME = "naslov";
    static final String KEY_COST = "datum";
    static final String KEY_DESC = "text";
    static final String KEY_LINK = "link";
    static final String KEY_LINK1 = "doc";
    ArrayList<HashMap<String, String>> menuItems;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

                View view =inflater.inflate(R.layout.activity_main, null);
        Log.w("Aplikacija_view","Startovana" );
        return view;

    }
    @Override
    public void onResume() {
        Log.w("Aplikacija_resume","Startovana" );
        new loadListView().execute();

    }

    public class loadListView extends AsyncTask<Integer, String, String> 
    {
        @Override protected void onPreExecute() 
        { 

            Toast.makeText(getActivity(), "Ucitavanje...", Toast.LENGTH_LONG).show();

        super.onPreExecute();
        } 
        @Override protected String doInBackground(Integer... args) 
        { // updating UI from Background Thread 
        menuItems = new ArrayList<HashMap<String, String>>();
            final XMLParser parser = new XMLParser();
            String xml = parser.getXmlFromUrl(URL); // getting XML
            Document doc = parser.getDomElement(xml); // getting DOM element

            NodeList nl = doc.getElementsByTagName(KEY_ITEM);
            // 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_NAME, parser.getValue(e, KEY_NAME));
                map.put(KEY_COST, "Datum: " + parser.getValue(e, KEY_COST));
                map.put(KEY_DESC, parser.getValue(e, KEY_DESC));
                map.put(KEY_LINK, parser.getValue(e, KEY_LINK));
                map.put(KEY_LINK1, parser.getValue(e, KEY_LINK1));

                // adding HashList to ArrayList
                menuItems.add(map);

            }

        return null; 
        } 
        @Override protected void onPostExecute(String args)
        { 
            Toast.makeText(getActivity(), "Ucitano", Toast.LENGTH_LONG).show();
            String[] from = { KEY_NAME, KEY_DESC, KEY_COST,KEY_LINK,KEY_LINK1};

            /** Ids of views in listview_layout */
            int[] to = { R.id.naslov, R.id.novost, R.id.datum,R.id.link,R.id.link1};

            // Instantiating an adapter to store each items
            // R.layout.listview_layout defines the layout of each item
            SimpleAdapter adapter = new SimpleAdapter(getActivity().getBaseContext(), menuItems, R.layout.listview_layout, from, to);        

            // Setting the adapter to the listView
            setListAdapter(adapter);



                } 
                }


}

应用程序总是失败的。我需要编辑什么？

你忘记super.onResume()打电话了，好像：

  ...
  ...

  @Override
  public void onResume() {
      super.onResume(); // don't forget to call super.onResume()
      Log.w("Aplikacija_resume","Startovana" );
      new loadListView().execute();

  }  

  ...
