Android-Pull way to parse XML data

XML file creation Apache server has been established in the last introduced, where no more than elaborate
text:
Add the jar package

implementation 'com.squareup.okhttp3:okhttp:3.4.1'

Apply for network permissions in the closure

<uses-permission android:name="android.permission.INTERNET"/>

There is only a Button in the layout file, which will not be explained here. The parsed XML data will reflect the
MainActivity.java code in log mode as follows:

public class MainActivity extends AppCompatActivity {
    private Button Request;
    private TextView ResponseText;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Request = (Button) findViewById(R.id.Click);
        ResponseText = (TextView) findViewById(R.id.Response);

        Request.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                SendRequestToOkhttp();
            }
        });
    }
    private void SendRequestToOkhttp() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    OkHttpClient Client = new OkHttpClient();
                    Request request = new Request.Builder().url("http://192.168.0.60/data.xml").build();//发送请求
                    Response response = Client.newCall(request).execute();//发送请求并获取服务器返回的数据
                    String ResponseData = response.body().string();//获取具体数据
                    ParseXMLWithPull(ResponseData);//显示数据
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }

    private void ParseXMLWithPull(String XMLData){
        try{
            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            XmlPullParser xmlPullParser = factory.newPullParser();
            xmlPullParser.setInput(new StringReader(XMLData));
            int eventType = xmlPullParser.getEventType();//设置初始节点

                String nodename = xmlPullParser.getName();
                //判断标签类型
                switch (eventType){
                    //开始解析
                    case XmlPullParser.START_TAG:{//开始标签
                        if ("id".equals(nodename)){
