android 讀取xml

在有些應用中，有一點小數據，直接存儲在XML就是，實現較為簡單，

1、xml文件放入asset文件夾，結構如：

2 、構建message類，解析xml類PullParseService

3、在activity中調用。

具體代碼如下：

1.解析xml類

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 getMessages(InputStream inputStream) throws Exception{
ArrayList 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();//
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每個對象信息類

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、讀取xml數據應用到應用中

AssetManager asset = getAssets();
try {
InputStream input=asset.open("message.xml");
List list = null;
try {
list = PullParseService.getMessages(input);

String tag="xmllllll";
int id =(int) (Math.random()*12);
Log.i(tag, list.get(id).getContent());
//將內容發布廣播
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();
}
