效果图：

1.src文件夹下 ShowActivity.java文件内容：

 

package com.jun.activity;


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

import com.jun.adapter.MyAdapter;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.GridView;
import android.widget.SimpleAdapter;public class ShowActivity extends Activity {    private GridView gridView=null;    private MyAdapter adapter=null;    private SimpleAdapter adapter1=null;    private List> list=null;    private HashMap map=null;    private String data[]={"图片1","图片2","图片3","图片4","图片5","图6","图片7","图片8","图片9",            "图片10","图片11","图片12","图片13","图片14","图片15","图片16"};    private int   imgId[]={R.drawable.a,R.drawable.a,R.drawable.a,R.drawable.a,R.drawable.a,
            R.drawable.a,R.drawable.a,R.drawable.a,R.drawable.a,R.drawable.a,R.drawable.a,
            R.drawable.a,R.drawable.a,R.drawable.a,R.drawable.a,R.drawable.a};
    @Override    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_show);
        init();
        setData();
    }private void init(){
    
    gridView=(GridView) findViewById(R.id.grid_view);
    list=new ArrayList>();
}private void setData(){//    使用BaseAdapter添加数据
    adapter=new MyAdapter(ShowActivity.this, data, imgId);
    
    gridView.setAdapter(adapter);    
    
    
//    使用SimpeAdapter添加数据//    for(int i=0;i();//        //        map.put("text", data[i]);//        map.put("img", imgId[i]);//        list.add(map);//        //    }//    adapter1=new SimpleAdapter(ShowActivity.this, list, R.layout.gridview_item, new String[]{"text","img"}, new int[]{R.id.gridview_text,R.id.gridview_img});//    gridView.setAdapter(adapter1);}
    @Override    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_show, menu);        return true;
    }
}

 

2.ShowActivity布局文件activity_show.xml文件内容：

 



    
    
        

 

3.继承自BaseAdapter适配器类MyAdapter.java文件内容：

 

package com.jun.adapter;

import com.jun.activity.R;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;public class MyAdapter extends BaseAdapter {    private String data[]=null;    private int imgId[]=null;    private Context context=null;    private LayoutInflater inflater=null;    public MyAdapter(Context context,String[] data, int[] imgId) {
        super();        this.data = data;        this.imgId = imgId;        this.context = context;
        
        inflater=LayoutInflater.from(context);
    }

    @Override    public int getCount() {        // TODO Auto-generated method stub
        return data.length;
    }

    @Override    public Object getItem(int position) {        // TODO Auto-generated method stub
        return position;
    }

    @Override    public long getItemId(int position) {        // TODO Auto-generated method stub
        return position;
    }    private class Holder{
        
        TextView tv=null;
        ImageView img=null;        public TextView getTv() {            return tv;
        }        public void setTv(TextView tv) {            this.tv = tv;
        }        public ImageView getImg() {            return img;
        }        public void setImg(ImageView img) {            this.img = img;
        }
        
    }
    @Override    public View getView(int position, View convertView, ViewGroup parent) {        // TODO Auto-generated method stub//        获得holder以及holder对象中tv和img对象的实例
        Holder holder;        if(convertView==null){
            
            
            convertView=inflater.inflate(R.layout.gridview_item, null);
            holder=new Holder();
            holder.tv=(TextView) convertView.findViewById(R.id.gridview_text);
            holder.img=(ImageView) convertView.findViewById(R.id.gridview_img);
            
            convertView.setTag(holder);
            
        }else{
            holder=(Holder) convertView.getTag();
            
        }//        为holder中的tv和img设置内容
        holder.tv.setText(data[position]);
        holder.img.setImageResource(imgId[position]);//        注意  默认为返回null,必须得返回convertView视图
        return convertView;
    }

}

 

4.GridView组件上面的布局:   gridview_item.xml文件内容：
