案例二：同样的效果：
布局文件使用上面一样的：
定义一个ImageAdapter类，此类继承BaseAdapter如下：
01 package com.test;
02
03 import
Android.content.Context;
04 import
Android.view.View;
05 import
Android.view.ViewGroup;
06 import
Android.widget.BaseAdapter;
07 import
Android.widget.GridView;
08 import
Android.widget.ImageView;
09
10 public class GridViewAdapter extends BaseAdapter {
11
12 //定义Context
13 private Context mContext;
14
15 //定义整形数组 （图片资源）
16 private int [] mimages=
17 {
18 R.drawable.
Android,R.drawable.blackberry,R.drawable.windowshone,
19 R.drawable.windowshone,R.drawable.blackberry,R.drawable.
Android,
20 R.drawable.windowshone,R.drawable.
ios,R.drawable.blackberry
21
22 };
23
24 public GridViewAdapter(Context c)
25 {
26 mContext=c;
27 }
28
29 //获取图片的个数
30 @Override
31 public int getCount() {
32 // TODO Auto-generated method stub
33 return mimages.length;
34 }
35 // 获取图片在库中的位置
www.atcpu.com36 @Override
37 public Object getItem(int position) {
38 // TODO Auto-generated method stub
39 return position;
40 }
41
42 //获取图片ID
43 @Override
44 public long getItemId(int position) {
45 // TODO Auto-generated method stub
46 return position;
47 }
48
49 @Override
50 public View getView(int position, View convertView, ViewGroup parent)
51 {
52 ImageView mimageView;
53 if(convertView==null)
54 {
55 //给Imageview设置资源
56 mimageView = new ImageView(mContext);
57 //设置布局图片120*120显示
58
59 mimageView.setLayoutParams(new GridView.LayoutParams(85, 85));
60
61 mimageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
62
63 mimageView.setPadding(8, 8, 8, 8);
64 }else
65 {
66 mimageView=(ImageView) convertView;
67 }
68 mimageView.setImageResource(mimages[position]);
69 return mimageView;
70 }
71 }
01 package com.test;
02 import
java.util.ArrayList;
03 import
java.util.HashMap;
04 import
Android.app.Activity;
05 import
Android.os.Bundle;
06 import
Android.view.View;
07 import
Android.widget.AdapterView;
08 import
Android.widget.AdapterView.OnItemClickListener;
09 import
Android.widget.GridView;
10 import
Android.widget.SimpleAdapter;
11 import
Android.widget.Toast;
12 public class GridViewDemo_2 extends Activity {
13 private GridView gridView;
14 @Override
15 protected void onCreate(Bundle savedInstanceState) {
16 // TODO Auto-generated method stub
17 super.onCreate(savedInstanceState);
18 setContentView(R.layout.gridview_main);
19
20 gridView = (GridView)findViewById(R.id.gridview_main);
21
22 gridView.setAdapter(new GridViewAdapter(this));//调用GridViewAdapter
23
24 gridView.setOnItemClickListener(clickListener);
25 }
26
27 private OnItemClickListener clickListener =new OnItemClickListener() {
28
29 @Override
30 public void onItemClick(AdapterView<?> arg0, View arg1, int position,
31 long id) {
32 Toast.makeText(GridViewDemo_2.this, ""+position,Toast.LENGTH_SHORT).show();//显示信息;
33
34 }
35 };
36 }
效果：
