一、xml：

"1.0" encoding="utf-8"?>

    "1">
        tom
        20


    "2">
        kite
        21


    "3">
        rose
        22

二、Student类：

package com.amaker.pullparser;

public class Student {

    private int id;
    private int age;
    private String name;
    /**
     * 无参构造方法
     */
    public Student() {
        super();
    }
    /**
     * 带参构造方法
     */
    public Student(int id, int age, String name) {
        super();
        this.id = id;
        this.age = age;
        this.name = name;
    }


    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "Student [age=" + age + ", id=" + id + ", name=" + name + "]";
    }


}

三、MainActivity类：

package com.amaker.pullparser;

import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;

import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.util.Xml;

public class MainActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        List list = readXML();
        for(Student s:list){
            Log.i("test", s.toString());
        }

    }

    List readXML(){
        InputStream in = this.getClass().getClassLoader().getResourceAsStream("stu.xml");
        XmlPullParser parser = Xml.newPullParser();
        List studentList = new ArrayList();
        Student currentStudent = null;
        try {
            parser.setInput(in, "utf-8");
            int eventType = parser.getEventType();
            while(eventType!=XmlPullParser.END_DOCUMENT){
                switch (eventType) {

                case XmlPullParser.START_TAG:
                    String tagName = parser.getName();
                    if(tagName!=null&&tagName.equals("student")){
                        currentStudent = new Student();
                        int id = Integer.parseInt(parser.getAttributeValue(null,"id"));
                        currentStudent.setId(id);
                    }

                    if(tagName!=null&&tagName.equals("name")){
                        String name;
                        try {
                            name = parser.nextText();
                            currentStudent.setName(name);
                        } catch (IOException e) {
                            e.printStackTrace();
                        }

                    }

                    if(tagName!=null&&tagName.equals("age")){
                        String age;
                            try {
                                age = parser.nextText();
                                currentStudent.setAge(Integer.parseInt(age));
                            } catch (IOException e) {
                                e.printStackTrace();
                            }

                    }
                    break;

                case XmlPullParser.END_TAG:
                    if(parser.getName().equals("student")){
                        studentList.add(currentStudent);
                    }
                    break;
                default:
                    break;
                }
                eventType = parser.next();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return studentList;
    }
}
