步骤：

1.ListView及ListView_Item

2.实体类的编写

3.自定义适配器的书写

4.ListView的绑定数据源与控件

部分代码如下：

package cn.edu.bzu.adapter;
 
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
 
 
import org.w3c.dom.Text;
 
import java.util.List;
 
import cn.edu.bzu.entity.Bean;
import cn.edu.bzu.listview_demo.R;
 

public class MyListViewAdapter extends BaseAdapter {
    private LayoutInflater mInflater; //LayoutInflater是用来找layout下xml布局文件，并且实例化
    private List<Bean> mlist;
    public MyListViewAdapter(Context context,List<Bean> list) {
        mInflater=LayoutInflater.from(context); //得到初始化上下文
        mlist=list;
    }
    @Override
    public int getCount() {
        return mlist.size();
    }
 
    @Override
    public Object getItem(int position) {
        return mlist.get(position);
    }
 
    @Override
    public long getItemId(int position) {
        return position;
    }
 
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder=null;
        if(convertView==null){
            convertView=mInflater.inflate(R.layout.listview_item,null);  //将布局转换成视图
            holder=new ViewHolder();
            holder.mTitle=(TextView)convertView.findViewById(R.id.id_title);
            holder.mDesc=(TextView)convertView.findViewById(R.id.id_desc);
            holder.mDate=(TextView)convertView.findViewById(R.id.id_time);
            holder.mPhone=(TextView)convertView.findViewById(R.id.id_phone);
            convertView.setTag(holder);
        }else {
            //ViewHolder被复用
            holder=(ViewHolder)convertView.getTag();
        }
        holder.mTitle.setText(mlist.get(position).getTitle());
        holder.mDesc.setText(mlist.get(position).getDesc());
        holder.mPhone.setText(mlist.get(position).getPhone());
        holder.mDate.setText(mlist.get(position).getDate());
        return convertView;
    }
    private class ViewHolder{
        TextView mTitle;
        TextView mDesc;
        TextView mDate;
        TextView mPhone;
    }
}

注意：在继承BaseAdapter 需要实现getCount，getItem，getItemId，getView，以及构造方法 等方法

package cn.edu.bzu.weibo_looking;
 
import java.util.ArrayList;
import java.util.List;
 
import cn.edu.bzu.adapter.MyAdapter;
import cn.edu.bzu.entity.Information;
import android.os.Bundle;
import android.widget.ListView;
import android.app.Activity;
 
public class MainActivity extends Activity {
    private ListView listView;
    private MyAdapter adapter;
    private List<Information> list;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setData();//数据源
         initView();
    }
    private void initView() {
        // 初始化控件
        listView=(ListView) findViewById(R.id.Lv);
        listView.setAdapter(adapter);  //绑定适配器
    }
    private void setData() {
        // 设置数据源
         list=new ArrayList<Information>();
        list.add(new Information(R.drawable.img1,"拉拉卡卡","2015-04-28","今天心情很好，很开心"));
        list.add(new Information(R.drawable.img2, "潇湘雨", "2015-04-29", "今天认识了好多朋友，好高兴"));
        list.add(new Information(R.drawable.img3,"鸣人","2015-04-30","我又开始追动漫了，加油！"));
        adapter=new MyAdapter(list, MainActivity.this);
    }           
}

此程序完成！
