如何从 XML 文件中获取 id 和 value 到 android 中的对话框

Question

这个问题已经持续了一周，我需要帮助，我怎样才能获得语言类型的值并在对话框中显示 id，这样它就会在这个对话框中显示英语、法语等语言，我将等待接受有效的答案。我真的不知道如何获取此信息并将其显示在对话框列表中。

XML

  <streamlanguage>
      <language_type id="English">
      http://154.obj.netromedia.net/IMMPowered/Aucoms1/playlist.m3u8
      </language_type>
      <language_type id="French">
      http://155.obj.netromedia.net/ipadhigh/Frenchlanx/playlist.m3u8
      </language_type>
      <language_type id="German">
      http://155.obj.netromedia.net/ipadhigh/Germanlanx/playlist.m3u8
      </language_type>
      <language_type id="Russian">
      http://155.obj.netromedia.net/ipadhigh/Russianlanx/playlist.m3u8
      </language_type>
      <language_type id="Arabic">
      http://155.obj.netromedia.net/ipadhigh/Arabiclanx/playlist.m3u8
      </language_type>
       <language_type id="Hindi">
      http://155.obj.netromedia.net/ipadhigh/Hindilanx/playlist.m3u8
      </language_type>
      <language_type id="Portuguese">
      http://155.obj.netromedia.net/ipadhigh/Portulanx/playlist.m3u8
     </language_type>
 </streamlanguage>

活动

public class Language extends Activity {

   String URL = "";

   static final String KEY_LANG = "streamlanguage";
   static final String KEY_ID = "id";
   static final String KEY_TITLE = "language_type";

   ArrayList<String> menuItems;
   ArrayList<String> menuKeys;


    @Override
   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.commentlayout);

    XMLParser parser = new XMLParser();
    String xml = parser.getXmlFromUrl(URL); // getting XML
    Document doc = parser.getDomElement(xml); // getting DOM element

    NodeList nl = doc.getElementsByTagName("KEY_LANG");

    for (int i = 0; i < nl.getLength(); i++) {
        Element e = (Element) nl.item(i);
        List<String> list = new ArrayList<String>();
        list.add("("+parser.getValue(e, KEY_ID)+") "+parser.getValue(e, KEY_TITLE));       
        }
    }
}

试试这个

    NodeList nodeList = document.getElementsByTagName("language_type");
    for(int x=0,size= nodeList.getLength(); x<size; x++) {
        System.out.println(nodeList.item(x).getAttributes().getNamedItem("id").getNodeValue());
         System.out.println(nodeList.item(x).getTextContent());
    }
