1、根据xml的结点定义JavaBean

</newslist>

public class News {
	private String title;
	private String detail;
	private String comment;
	private String imageUrl;
	
	@Override
	public String toString() {
		return "News [title=" + title + ",detail=" + detail + ",comment="
				+ comment + ",imageUrl=" + imageUrl + "]";
	}
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	public String getDetail() {
		return detail;
	}
	public void setDetail(String detail) {
		this.detail = detail;
	}
	public String getComment() {
		return comment;
	}
	public void setComment(String comment) {
		this.comment = comment;
	}
	public String getImageUrl() {
		return imageUrl;
	}
	public void setImageUrl(String imageUrl) {
		this.imageUrl = imageUrl;
	}
		
}

2 解析代码

public class MainActivity extends Activity {
	List<News> newsList;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		getNewsInfo();
	}

    //开辟子线程下载新闻
	private void getNewsInfo() {
		Thread t = new Thread(){
			@Override
			public void run() {
				String path = "http://192.168.13.13:8080/news.xml";
				try {
					URL url = new URL(path);
					HttpURLConnection conn = (HttpURLConnection) url.openConnection();
					conn.setRequestMethod("GET");
					conn.setConnectTimeout(5000);
					conn.setReadTimeout(5000);
					//发送http GET请求，获取相应码
					if(conn.getResponseCode() == 200){
						InputStream is = conn.getInputStream();
						//使用pull解析器，解析这个流
						parseNewsXml(is);
					}
				} catch (Exception e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		};
		t.start();
	}
	
	private void parseNewsXml(InputStream is) {
		XmlPullParser xp = Xml.newPullParser();
		try {
			xp.setInput(is,"utf-8");
			//对节点的事件类型进行判断，就可以知道当前节点是什么节点
			int type = xp.getEventType();
			News news = null;
			while(type != XmlPullParser.END_DOCUMENT){
				switch (type) {
				case XmlPullParser.START_TAG:
					if("newslist".equals(xp.getName())){
						newsList = new ArrayList<News>();
					}
					else if("news".equals(xp.getName())){
						news = new News();
					}
					else if("title".equals(xp.getName())){
						String title = xp.nextText();
						news.setTitle(title);
					}
					else if("detail".equals(xp.getName())){
						String detail = xp.nextText();
						news.setDetail(detail);
					}
					else if("comment".equals(xp.getName())){
						String comment = xp.nextText();
						news.setComment(comment);
					}
					else if("image".equals(xp.getName())){
						String image = xp.nextText();
						news.setImageUrl(image);
					}
					break;
				case XmlPullParser.END_TAG:
					if("news".equals(xp.getName())){
                        //把news对象放着到集合中去
						newsList.add(news);
					}
					break;
				}
				//解析完当前节点后，把指针移动至下一个节点，并返回它的事件类型
				type = xp.next();
			}
			
			//发消息，让主线程设置listview的适配器，如果消息不需要携带数据，可以发送空消息
			handler.sendEmptyMessage(1);
			
			//用于测试 查看数据是否获取正确
//			for (News n : newsList) {
//				System.out.println(n.toString());
//			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
