Android解析XML(PULL)展示到ListView

Android解析XML展示到ListView运行后的效果图如下：

服务端的请求页面

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>Insert title here 获取XML数据

服务端返回结果的页面

<?xml version="1.0" encoding="UTF-8" ?><%@ page language="java" contentType="text/xml; charset=UTF-8" pageEncoding="UTF-8"%><%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>   ${s.sex}

服务端的Java代码

package com.zking.action;import java.util.ArrayList;import java.util.List;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionSupport;import com.zking.entity.Student;public class StudentAction extends ActionSupport{public String getXML() throws Exception { //查询数据库，获取数据 List students=new ArrayList<>(); for (int i = 1; i <=20; i++) {  Student student=new Student("小霜"+i, "女");  students.add(student); } //将对象集合保存到请求域中 ServletActionContext.getRequest().setAttribute("students", students); return "dataResult"; } }

服务端的配置文件（struts.xml）

<?xml version="1.0" encoding="UTF-8" ?>       /dataResult.jsp

服务端的运行结果

Android （布局文件 activity_main.xml）

<?xml version="1.0" encoding="utf-8"?>

Android（Java代码 MainActivity）

package com.example.g150825_android29_parsexml;import android.app.ProgressDialog;import android.os.AsyncTask;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import android.util.Xml;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.LinearLayout;import android.widget.ListView;import android.widget.TextView;import org.xmlpull.v1.XmlPullParser;import java.io.BufferedReader;import java.io.InputStream;import java.io.InputStreamReader;import java.net.HttpURLConnection;import java.net.MalformedURLException;import java.net.URL;import java.util.ArrayList;import java.util.List;public class MainActivity extends AppCompatActivity { List studentList=new ArrayList<>(); private ListView lv_main_list; private MyAdater myAdater; private ProgressDialog progressDialog; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //实例化进度条对话框 progressDialog = new ProgressDialog(this); progressDialog.setMessage("正在拼命加载中....."); lv_main_list = (ListView) findViewById(R.id.lv_main_list); //实例化适配器 //设置适配器 myAdater = new MyAdater(); lv_main_list.setAdapter(myAdater); } class MyAdater extends BaseAdapter{ @Override public int getCount() {  return studentList.size(); } @Override public Object getItem(int i) {  return studentList.get(i); } @Override public long getItemId(int i) {  return i; } @Override public View getView(int i, View view, ViewGroup viewGroup) {  LinearLayout linearLayout=new LinearLayout(MainActivity.this);  linearLayout.setOrientation(LinearLayout.HORIZONTAL);  TextView textViewName=new TextView(MainActivity.this);  textViewName.setText(studentList.get(i).getName());  TextView textViewSex=new TextView(MainActivity.this);  textViewSex.setText(studentList.get(i).getSex());  linearLayout.addView(textViewName);  linearLayout.addView(textViewSex);  return linearLayout; } } public void getXML(View view){ new MyTask().execute(); } class MyTask extends AsyncTask{ private Student student; @Override protected void onPreExecute() {  super.onPreExecute();  progressDialog.show(); } @Override protected Object doInBackground(Object[] objects) {  //01.确定网络数据  String path="http://192.168.43.152:8080/G150825_S2SH/studentActiongetXML.action";  try {  //02.实例化URL  URL url=new URL(path);  //03.获取连接对象  HttpURLConnection httpURLConnection= (HttpURLConnection) url.openConnection();  //04.设置请求方式  httpURLConnection.setRequestMethod("GET");  //05.设置请求连接超时的时间(优化)  httpURLConnection.setConnectTimeout(5000);  //06.获取响应码（结果码）  int code=httpURLConnection.getResponseCode();  if (code==200){   //07.获取服务器返回过来的数据   InputStream is=httpURLConnection.getInputStream();   //测试（打印）   //缓冲字符流//   BufferedReader br=new BufferedReader(new InputStreamReader(is));//   String str=null;//   while ((str=br.readLine())!=null){//   Log.i("test",str);//   }   //解析XML（PULL）   XmlPullParser xmlPullParser=Xml.newPullParser();   xmlPullParser.setInput(is,"UTF-8");   int type=xmlPullParser.getEventType();   while (type!=XmlPullParser.END_DOCUMENT){   switch (type){    case XmlPullParser.START_TAG:    //获取开始标签    String startTagName=xmlPullParser.getName();    if ("student".equals(startTagName)){     student = new Student();     //获取name属性值     String name=xmlPullParser.getAttributeValue(0);     student.setName(name);    }else if("sex".equals(startTagName)){     //获取sex的文本值     String sex=xmlPullParser.nextText();     student.setSex(sex);    }    break;    case XmlPullParser.END_TAG:    //获取到结束标签的名字    String endTagName=xmlPullParser.getName();    if("student".equals(endTagName)){     studentList.add(student);    }    break;   }   type=xmlPullParser.next();   }  }  } catch (Exception e) {  e.printStackTrace();  }  return null; } @Override protected void onPostExecute(Object o) {  super.onPostExecute(o);  //通知适配器发生改变  myAdater.notifyDataSetChanged();  progressDialog.cancel(); } }}

Android （实体类 Student）

package com.example.g150825_android29_parsexml;public class Student { private String name; private String sex; public Student() { super(); // TODO Auto-generated constructor stub } public Student(String name, String sex) { super(); this.name = name; this.sex = sex; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; }}

在清单文件中添加权限即可（AndroidManifest.xml）
