我想通过我的活动从我的内部存储传递一个 xml 文件:我的错误:
07-06 01:58:39.494: E/Error:(15253): Unexpected token (position:TEXT /sdcard/xml.xlm...@1:24 in java.io.StringReader@4152db98)
ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();
XMLParserLocal parser = new XMLParserLocal();
//String xml = parser.getXmlFromUrl(URL); // getting XML
Document doc = parser.getDomElement("storage/emulated/0/xml.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_ID, parser.getValue(e, KEY_ID));
map.put(KEY_NAME, parser.getValue(e, KEY_NAME));
map.put(KEY_COST, parser.getValue(e, KEY_COST));
map.put(KEY_COST2, parser.getValue(e, KEY_COST2));
map.put(KEY_DESC, parser.getValue(e, KEY_DESC));
map.put(KEY_texton, parser.getValue(e, KEY_texton));
map.put(KEY_textoff, parser.getValue(e, KEY_textoff));
// adding HashList to ArrayList
menuItems.add(map);
}
// Adding menuItems to ListView
ListAdapter adapter = new SimpleAdapter(this, menuItems,
R.layout.list_item,
new String[] { KEY_NAME, KEY_DESC, KEY_ID, KEY_COST, KEY_texton, KEY_textoff}, new int[] {
R.id.name, R.id.desciption, R.id.cost, R.id.deviceid,R.id.on,R.id.off });
setListAdapter(adapter);
// selecting single ListView item
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String name = ((TextView) view.findViewById(R.id.name)).getText().toString();
String cost = ((TextView) view.findViewById(R.id.cost)).getText().toString();
String deviceid = ((TextView) view.findViewById(R.id.deviceid)).getText().toString();
String description = ((TextView) view.findViewById(R.id.desciption)).getText().toString();
String on = ((Button) view.findViewById(R.id.on)).getText().toString();
String off = ((Button) view.findViewById(R.id.off)).getText().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra(KEY_NAME, name);
in.putExtra(KEY_COST, cost);
in.putExtra(KEY_DESC, description);
in.putExtra(KEY_ID, deviceid);
in.putExtra(KEY_texton, on);
in.putExtra(KEY_textoff, off);
startActivity(in);
}
});

有人可以帮我解决我的问题吗?
编辑:
这里是我的 xml,我想通过我的 Activity 传递,我在部分 xml 上取空了还有其他词:
<?xml version="1.0" encoding="utf-8"?>
