这是前几天从网上找的，连接是http://www.cnblogs.com/zhengbeibei/archive/2013/05/14/3078805.html
最简单的listview的使用
MainActivity如下：
package cn.com.wanda.activity;

import java.util.ArrayList;
import java.util.HashMap;

import com.example.listview.R;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;

public class MyListView extends Activity{
private ListView lv;
@Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);

    lv= (ListView) findViewById(R.id.LV_listview);    ArrayList<HashMap<String, Object>> listitem = new ArrayList<HashMap<String,Object>>();    for(int i=0;i<10;i++){        HashMap<String, Object> map = new HashMap<String, Object>();        map.put("itemTitle", "第"+i+"行");        map.put("itemtext", "这是第"+i+"行");        map.put("itemphone",R.drawable.ic_launcher);        listitem.add(map);    }    SimpleAdapter simpleAdapter = new SimpleAdapter(this,listitem, R.layout.simple_list_item,            new String[]{"itemTitle","itemtext","itemphone"},             new int[]{R.id.textview_TV,R.id.LV_listview,R.id.textview_TV});    lv.setAdapter(simpleAdapter);    lv.setOnItemClickListener(new OnItemClickListener() {        @Override        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {            // TODO Auto-generated method stub            int a= arg2;            int b= 0;            a++;            b=a;            Toast.makeText(getApplicationContext(), "你点击了第"+b+"行", Toast.LENGTH_SHORT).show();        }    });}

}
不用贴xml了吧
