我对SherlockListFtagment和xml解析器有问题。在ListActivity上使用AsyncTask,没有问题。我需要编辑什么来处理ListFragment。
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);
}
}
}
应用程序正在逐步完善。我需要编辑什么?
