从网址解析的Android ListFragment（sherlock）xml(Android ListFragment (sherlock) xml parsing from url)

从网址解析的Android ListFragment（sherlock）xml(Android ListFragment (sherlock) xml parsing from url)

我有SherlockListFtagment和xml解析器的问题。 在ListActivitiy上使用AsyncTask并没有问题。 我需要编辑什么来处理ListFragment。

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); } } }

应用程序总是很新鲜。 我需要编辑什么？

I have problem with SherlockListFtagment and xml parser. On ListActivitiy working with AsyncTask and no have problem. What I need edit for working on ListFragment.

Code:

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); } } }

最满意答案

你忘了super.onResume()调用，似乎：

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

You forgot super.onResume() call, it seems:

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