在有些应用中，有一点小数据，直接存储在XML就是，实现较为简单，

1、xml文件放入asset文件夹，结构如：

<?xml version="1.0" encoding="UTF-8" ?>
<messages><message id="1"><title>3月毕业证数码像采集</title><date1>3</date1><content>3月12日左右全年一次毕业证数码像采集，由新华社负责</content><url>23</url></message><message id="2"><title>3、9月课程注册</title><date1>3</date1><content>3月15日、9月15日本学期所修课程注册、课本征订，包括课程修完学员论文注册</content><url>23</url>

</message>

</messages>

2 、构建message类，解析xml类PullParseService

3、在activity中调用。

具体代码如下：

1.解析xml类

package com.edu.notice;

import java.io.InputStream;
import java.util.ArrayList;
import org.xmlpull.v1.XmlPullParser;

import android.util.Xml;

public class PullParseService {
 public static ArrayList <Message>getMessages(InputStream inputStream) throws Exception{
  ArrayList<Message> messages =null;
  Message message =null;
  XmlPullParser parser = Xml.newPullParser();
  parser.setInput(inputStream, "UTF-8");  
  int event = parser.getEventType();//
  while(event!=XmlPullParser.END_DOCUMENT){  
   switch(event){  
        case XmlPullParser.START_DOCUMENT://
               messages = new ArrayList<Message>();//  
                  break;  
        case XmlPullParser.START_TAG://
                  if("message".equals(parser.getName())){//
                       message = new Message();  
                       message.setId(Integer.parseInt(parser.getAttributeValue(0)));//
                   }  
                   if(message!=null){  
                       if("title".equals(parser.getName())){//
                          message.setTitle(parser.nextText());  
                       }else if("date1".equals(parser.getName())){//
                          message.setData1(Integer.parseInt(parser.nextText()));  
                       }else if("content".equals(parser.getName())){
                        message.setContent(parser.nextText());
                       }else if("url".equals(parser.getName())){
                        message.setUrl(parser.nextText());
                       }
                   }  
                   break;  
               case XmlPullParser.END_TAG://
                   if("message".equals(parser.getName())){// 
                    messages.add(message);//
                    message = null;  
                   }  
                   break;  
              }  
              event = parser.next();//
         }//end while 
  return messages;
  
 };
}

2、xml每个对象信息类

package com.edu.notice;

public class Message {
 private int id;
 private String title;
 private int data1;
 private String content;
 private String url;
 /**
  * @return the id
  */
 public int getId() {
  return id;
 }
 /**
  * @param id the id to set
  */
 public void setId(int id) {
  this.id = id;
 }
 /**
  * @return the title
  */
 public String getTitle() {
  return title;
 }
 /**
  * @param title the title to set
  */
 public void setTitle(String title) {
  this.title = title;
 }
 /**
  * @return the data1
  */
 public int getData1() {
  return data1;
 }
 /**
  * @param data1 the data1 to set
  */
 public void setData1(int data1) {
  this.data1 = data1;
 }
 /**
  * @return the content
  */
 public String getContent() {
  return content;
 }
 /**
  * @param content the content to set
  */
 public void setContent(String content) {
  this.content = content;
 }
 /**
  * @return the url
  */
 public String getUrl() {
  return url;
 }
 /**
  * @param url the url to set
  */
 public void setUrl(String url) {
  this.url = url;
 }
 
 
 
}

3、读取xml数据应用到应用中

AssetManager  asset =  getAssets();
         try {
    InputStream input=asset.open("message.xml");
    List<Message> list = null;
    try {
     list = PullParseService.getMessages(input);
     
     String tag="xmllllll";
     int id =(int) (Math.random()*12);
     Log.i(tag, list.get(id).getContent());
  //将内容发布广播
     setReminder(true, list.get(id).getContent());
     
     
    } catch (Exception e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }
    
   } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
