首先看一下这个简单的xml文件

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

-1℃/5℃
多云
南风3-4级
上海
200

-1℃/5℃
多云
南风3-4级
北京7-8
800

-7℃/5℃
多云
南风3-4级
哈尔滨
100

然后我们直接解析这个xml文件，在textview中显示一下

这里是代码，首先是业务Bean

package com.linuxidc.weather;

public class WeatherBean {

private int id;
private String name;
private String wind;
private String weather;
private String temp;
private String pm;

@Override
public String toString() {
return "WeatherBean [id=" + id + ", name=" + name + ", wind=" + wind
+ ", weather=" + weather + ", temp=" + temp + ", pm=" + pm
+ "]";
}

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public String getName() {
return name;
}

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

public String getWind() {
return wind;
}

public void setWind(String wind) {
this.wind = wind;
}

public String getWeather() {
return weather;
}

public void setWeather(String weather) {
this.weather = weather;
}

public String getTemp() {
return temp;
}

public void setTemp(String temp) {
this.temp = temp;
}

public String getPm() {
return pm;
}

public void setPm(String pm) {
this.pm = pm;
}
}

然后是解析xml文件的主要代码

package com.linuxidc.weather;

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

import org.xmlpull.v1.XmlPullParser;

import android.util.Xml;

public class ParseXml {

public static List parse(InputStream is) {
List list = null;
WeatherBean bean = null;
try {
XmlPullParser parser = Xml.newPullParser();
// 初始化解析器
parser.setInput(is, "utf-8");

int type = parser.next();
while (type != XmlPullParser.END_DOCUMENT) {
switch (type) {
case XmlPullParser.START_TAG:
if ("infos".equals(parser.getName())) {
list = new ArrayList();
} else if ("city".equals(parser.getName())) {
bean = new WeatherBean();
bean.setId(Integer.valueOf(parser.getAttributeva lue(0)));
} else if ("temp".equals(parser.getName())) {
String temp = parser.nextText();
bean.setTemp(temp);
} else if ("weather".equals(parser.getName())) {
String weather = parser.nextText();
bean.setWeather(weather);
} else if ("wind".equals(parser.getName())) {
String wind = parser.nextText();
bean.setWind(wind);
} else if ("name".equals(parser.getName())) {
String name = parser.nextText();
bean.setName(name);
} else if ("pm".equals(parser.getName())) {
String pm = parser.nextText();
bean.setPm(pm);
}
break;

case XmlPullParser.END_TAG:
if ("city".equals(parser.getName())) {
// 一个城市的信息处理完毕
list.add(bean);
bean = null;
}
break;
}

type = parser.next();
}
} catch (Exception e) {
e.printStackTrace();
}
return list;
}
}

最后在mainactivity中使用这个代码，使用类加载器完成这个简单的功能

package com.linuxidc.weather;

import java.util.List;

import android.os.Bundle;
import android.app.Activity;
import android.widget.TextView;

public class MainActivity extends Activity {
