2個類：1個實體類Person.java,1個繼承Activity的類

1.Person.java

package com.mrzhu.work_1_sax;

public class Person {
private String personId;
private String name;
private String address;
private String tel;
private String fax;
private String email;

public String getPersonId() {
  return personId;
}

public void setPersonId(String personId) {
  this.personId = personId;
}

public String getName() {
  return name;
}

public void setName(String name) {
  this.name = name;
}

public String getAddress() {
  return address;
}

public void setAddress(String address) {
  this.address = address;
}

public String getTel() {
  return tel;
}

public void setTel(String tel) {
  this.tel = tel;
}

public String getFax() {
  return fax;
}

public void setFax(String fax) {
  this.fax = fax;
}

public String getEmail() {
  return email;
}

public void setEmail(String email) {
  this.email = email;
}

@Override
public String toString() {
  return "Person [personId=" + personId + ", name=" + name + ", address="
    + address + ", tel=" + tel + ", fax=" + fax + ", email="
    + email + "]";
}
}

2.繼承Activity的類：

復制代碼代碼如下:

package com.mrzhu.work_1_sax;

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

import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.SAXException;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;

import android.app.Activity;
import android.os.Bundle;
import android.util.Xml;
import android.view.View;
import android.widget.Toast;

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

    public void pull(View v){
    pullParse();
    }

    public void pullParse(){
    List<Person> persons = null;
    Person person = null;
    InputStream in = null;
    try {
      XmlPullParser pullParser = Xml.newPullParser();
      in = getAssets().open("person.xml");
   pullParser.setInput(in, "utf-8");
   int eventType = pullParser.getEventType();
   while(eventType != XmlPullParser.END_DOCUMENT){
    String qName = pullParser.getName();
    switch(eventType){
    case XmlPullParser.START_DOCUMENT:
     persons = new ArrayList<Person>();
     break;
    case XmlPullParser.START_TAG:
     if("person".equalsIgnoreCase(qName)){
      person = new Person();
      person.setPersonId(pullParser.getAttributeValue(null, "personid"));
     }else if("name".equalsIgnoreCase(qName)){
      person.setName(pullParser.nextText());
     }else if("address".equalsIgnoreCase(qName)){
      person.setAddress(pullParser.nextText());
     }else if("tel".equalsIgnoreCase(qName)){
      person.setTel(pullParser.nextText());
     }else if("fax".equalsIgnoreCase(qName)){
      person.setFax(pullParser.nextText());
     }else if("email".equalsIgnoreCase(qName)){
      person.setEmail(pullParser.nextText());
     }
     break;
    case XmlPullParser.END_TAG:
     if("person".equalsIgnoreCase(qName)){
      persons.add(person);
     }
     break;
    }
    eventType = pullParser.next();
   }
   in.close();
  } catch (XmlPullParserException e) {
   e.printStackTrace();
  } catch (IOException e) {
   e.printStackTrace();
  }

    for (Person person2 : persons) {
   Toast.makeText(this, person2.toString(), Toast.LENGTH_SHORT).show();
  }
    }
}

main.xml

復制代碼代碼如下:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

</LinearLayout>

放在assets文件夾下的person.xml文件

復制代碼代碼如下:

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

 <person personid="E01">
  <name>Tony Blair</name>
  <address>10 Downing Street, London, UK</address>
