一:java代码:

com.baseadapter.activity.MainActivity

package com.baseadapter.activity;
import java.util.ArrayList;
import java.util.List;
import com.baseadapter.adapter.MoreListAdapter;
import com.baseadapter.entity.More;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;

public class MainActivity extends Activity {
	
	private ListView listView;
	private List<More> data;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		// 获取组件对象
		listView = (ListView) findViewById(R.id.listView);
		//获取数据源
		data=getData();
		//实例化MoreListAdapter
		MoreListAdapter adapter=new MoreListAdapter(this,data);
		listView.setAdapter(adapter);
		
		listView.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				// TODO Auto-generated method stub
				System.out.println("点击了内容"+data.get(arg2).getTitle());
			}
		});
		
	}
	/**获得数据源*/
	public List<More> getData(){
		List<More> all=new ArrayList<More>();
		all.add(new More(R.drawable.ip_gicon01,"内容1",R.drawable.ip_sicon01));
		all.add(new More(R.drawable.ip_gicon02,"内容2",R.drawable.ip_sicon01));
		all.add(new More(R.drawable.ip_gicon04,"内容3",R.drawable.ip_sicon01));
		all.add(new More(R.drawable.ip_gicon05,"内容4",R.drawable.ip_sicon01));
		all.add(new More(R.drawable.ip_gicon06,"内容5",R.drawable.ip_sicon01));
		all.add(new More(R.drawable.ip_gicon08,"内容6",R.drawable.ip_sicon01));
		return all;
	}
	
	
}

com.baseadapter.adapter.MoreListAdapter

package com.baseadapter.adapter;
import java.util.List;
import com.baseadapter.activity.R;
import com.baseadapter.entity.More;

import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
/**自定义的适配器*/
public class MoreListAdapter extends BaseAdapter{
	private List<More> all;
	private LayoutInflater mLayoutInflater;
	public MoreListAdapter(Context context,List<More> all){
		this.all=all;
		mLayoutInflater=LayoutInflater.from(context);
	}
	
	@Override
	public int getCount() {
		return all.size();
	}

	@Override
	public Object getItem(int position) {
		return all.get(position); 
	}

	@Override
	public long getItemId(int position) {
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		if(convertView==null){
			convertView=mLayoutInflater.inflate(R.layout.layout_item,null);
			Log.i("listview","&&&&&&&&&&&&&&&&");
		}
		/**获取控件*/
		ImageView imageView=(ImageView) convertView.findViewById(R.id.icon1);
		TextView titleView=(TextView) convertView.findViewById(R.id.title);
		ImageView imagebtn=(ImageView) convertView.findViewById(R.id.icon2);
		/**从存放More对象的集合里面取出一个元素*/
		More item=all.get(position);
		/**将这个对象的属性值设置到上面的控件里面*/
		imageView.setImageResource(item.getImage());
		titleView.setText(item.getTitle());
		imagebtn.setImageResource(item.getBtn());
		return convertView;
	}

}

com.baseadapter.entity.more

package com.baseadapter.entity;
/**将显示在子布局里的内容封装在这个对象里*/
public class More {
	/**图片1*/
	private int  image;
	/**文本*/
	private String title;
	/**图片2*/
	private int btn;
	
	public More() {
		super();
	}
	public More(int image, String title, int btn) {
		super();
		this.image = image;
		this.title = title;
		this.btn = btn;
	}
	public int getImage() {
		return image;
	}
	public void setImage(int image) {
		this.image = image;
	}
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	public int getBtn() {
		return btn;
	}
	public void setBtn(int btn) {
		this.btn = btn;
	}

}

二:布局文件

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" 
    android:background="@android:color/white">

    <ListView
        android:id="@+id/listView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:divider="@drawable/ip_line01"/>

</LinearLayout>

ListView的子布局文件:layout_item.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/RelativeLayout1"
    android:layout_width="match_parent"
    android:layout_height="80dip"
    android:gravity="center_vertical">

    <ImageView android:id="@+id/icon1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dip"/>
     
    <TextView android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/icon1"
        android:layout_marginLeft="20dip"
        android:textColor="@android:color/black"/>
    
     <ImageView android:id="@+id/icon2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_marginRight="20dip"
        android:background="#00000000"/> 
     
</RelativeLayout>

效果如下:
