XMl的解析简单的方法

首先需要jia包
xstream-1.4.7.jar
Vo类

package com.zld.day06_03zk3demo.bean;

import java.io.Serializable;
import java.util.List;

import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamImplicit;

/*@XStreamAlias("DATA")*/
@XStreamAlias("DATA")
最外面的那层

public class XmlBean implements Serializable{

	/*@XStreamImplicit(itemFieldName="item")*/
	@XStreamImplicit(itemFieldName="item")
	public List<Item>item;
	public class Item implements Serializable{
		public String title;
		public String link;
		public String imgs;
		public String description;
		public String copyright;
		public String pubDate;
		public String comments;
	}
}

Mainactivity

package com.zld.day06_03zk3demo;

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

	@Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        list=new ArrayList<XmlBean.Item>();
        handler=new Handler(){
        	@Override
        	public void handleMessage(Message msg) {

        		list=(List<Item>) msg.obj;
        		MyAdapter adapter=new MyAdapter(list, MainActivity.this);
        		lv.setAdapter(adapter);
        	}
        };
        init();
    }

	private void init() {
		lv = (ListView) findViewById(R.id.main_lv);
		requestData();
		lv.setOnItemClickListener(new OnItemClickListener() {
			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				Intent it=new Intent(MainActivity.this,DetailsActivity.class);

	}

					}
