Android解析服务器端发来的xml数据

Android跟服务器交互数据，有时数据量大时，就需要以xml形式的交互数据。这里来实现服务器给Android客户端发送xml数据，Android客户端解析。

服务器端我使用dom4j第三方包来组织xml数据，大家可自行百度下载。而Android客户端则使用 XmlPullParser来解析xml数据。

服务器端代码：

[java] package servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.net.URLDecoder;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
public class getSms extends HttpServlet {
    public getSms() {
        super();
    }
    public void destroy() {
        super.destroy(); // Just puts "destroy" string in log
        // Put your code here
    }
    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html; charset=UTF-8" );
         request.setCharacterEncoding("UTF-8");

package servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.net.URLDecoder;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
public class getSms extends HttpServlet {
public getSms() {
  super();
}
public void destroy() {
  super.destroy(); // Just puts "destroy" string in log
  // Put your code here
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {
  response.setContentType("text/html; charset=UTF-8" );
   request.setCharacterEncoding("UTF-8");   [java] view plaincopyprint?Document document = DocumentHelper.createDocument();
             Element persons = DocumentHelper.createElement("persons");
             document.add(persons);

  Document document = DocumentHelper.createDocument();
               Element persons = DocumentHelper.createElement("persons");
               document.add(persons); [java] view plaincopyprint?persons.addElement("address").addText("南京");
persons.addElement("id").addAttribute(1);
persons.addElement("thread_id").addText(2);
persons.addElement("date").addText("2013");
persons.addElement("status").addText(-1);
persons.addElement("type").addText(0);
persons.addElement("body").addText("测试");

              persons.addElement("address").addText("南京");
              persons.addElement("id").addAttribute(1);
              persons.addElement("thread_id").addText(2);
              persons.addElement("date").addText("2013");
              persons.addElement("status").addText(-1);
              persons.addElement("type").addText(0);
              persons.addElement("body").addText("测试"); [java] view plaincopyprint?        String xml = document.asXML(); //用dom4j组织一个XML字符串
         response.setContentType("text/xml; charset=UTF-8"); //设置返回值的类型
         response.getOutputStream().write(xml.getBytes("UTF-8"));    //设置返回值
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

doGet(request,response);
}
public void init() throws ServletException {
    // Put your code here
}

   String xml = document.asXML(); //用dom4j组织一个XML字符串
          response.setContentType("text/xml; charset=UTF-8"); //设置返回值的类型
          response.getOutputStream().write(xml.getBytes("UTF-8"));    //设置返回值
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {

doGet(request,response);
}
public void init() throws ServletException {
// Put your code here
}

}

Android客户端：

[java] String url="http://10.0.2.2:8080/sms_server/servlet/getSms";
    try{
    URL u = new URL(url);
       HttpURLConnection conn = (HttpURLConnection) u.openConnection();
       conn.setRequestMethod("GET");
       if (conn.getResponseCode() == 200) {
           InputStream in = conn.getInputStream();
           XmlPullParser parser = Xml.newPullParser();
           parser.setInput(in, "UTF-8");
           int event = parser.getEventType();
      &n
