Question

我想从内部存储中传递xml文件与我的活动：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);

            }
        });

这里是我的XMLParserLocal：

            return this.getElementValue(n.item(0));
        }
}

有人可以帮我解决问题吗？

编辑：

这里我的xml我想通过我的Activity传递，我已经取消了xml的部分空白还有其他的话：

    <?xml version="1.0" encoding="utf-8"?>
    <devices>
    <device>
    <deviceid>empty</deviceid>
    <devicename>empty</devicename>
    <actions>empty</actions>
    <actions2>empty</actions2>
    <devicetype>empty</devicetype>
    <texton>empty</texton>
    <textoff>empty</textoff>
    </device>



  <device>
        <deviceid>empty</deviceid>
        <devicename>empty</devicename>
        <actions>empty</actions>
        <actions2>empty</actions2>
        <devicetype>empty</devicetype>
        <texton>empty</texton>
        <textoff>empty</textoff>
        </device>


  </devices>

Answer 1

您在上面发布的XML无效。

</device>
<device>
<device>

连续两个打开的设备标签。然后在结束xml部分之前打开另一个

<device>
</devices>

从本地存储传递xml文件
