Android--使用Pull解析器解析xml文件

2个类：1个实体类Person.java,1个继承Activity的类

 

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.继承Activity的类：

 

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

 

<?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" >

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:onClick="pull"
        android:text="pull" />

</LinearLayout>

 

 

放在assets文件夹下的person.xml文件
