Android中用GridView实现九宫格的两种方法

1.传统办法：实现一个继承BaseAdapter的 ImageAdapter

java代码如下：

[java] view plaincopy

1. package com.test;  
2.   
3. import android.app.Activity;  
4. import android.content.Context;  
5. import android.os.Bundle;  
6. import android.view.LayoutInflater;  
7. import android.view.View;  
8. import android.view.ViewGroup;  
9. import android.widget.AdapterView;  
10. import android.widget.BaseAdapter;  
11. import android.widget.GridView;  
12. import android.widget.ImageView;  
13. import android.widget.TextView;  
14. import android.widget.Toast;  
15. import android.widget.AdapterView.OnItemClickListener;  
16.   
17. public class GridViewActivity extends Activity {  
18.   
19.     //存放各功能图片  
20.     private Integer[] mFunctionPics = {R.drawable.mobilesecurity,R.drawable.infosecurity,  
21.             R.drawable.no_interrupt,R.drawable.bianjiejieting,R.drawable.xiaomishu  
22.             ,R.drawable.sms_send_attime,R.drawable.yule,R.drawable.setting};  
23.     //存放各功能的名称  
24.     private Integer[] mFunctionName = {R.string.phone_tools_box_name1,  
25.             R.string.phone_tools_box_name2,R.string.phone_tools_box_name3,  
26.             R.string.phone_tools_box_name4,R.string.phone_tools_box_name5,  
27.             R.string.phone_tools_box_name6,R.string.phone_tools_box_name7,  
28.             R.string.phone_tools_box_name8};  
29.     @Override  
30.     protected void onCreate(Bundle savedInstanceState) {  
31.         super.onCreate(savedInstanceState);  
32.         setContentView(R.layout.gridview_main);  
33.           
34.         GridView girdview = (GridView) this.findViewById(R.id.girdview);  
35.         girdview.setAdapter(new ImageAdapter(this));  
36.         girdview.setOnItemClickListener(new OnItemClickListener() {  
37.             @Override  
38.             public void onItemClick(AdapterView<?> parent, View view,  
39.                     int position, long id) {  
40.                 Toast.makeText(GridViewActivity.this, "图片ID："+mFunctionPics[position],1).show();  
41.             }  
42.         });  
43.           
44.     }  
45.       
46.     public class ImageAdapter extends BaseAdapter{  
47.   
48.         private Context mContext;  
49.         private LayoutInflater inflater;  
50.         private class GirdTemp{  
51.             ImageView phone_function_pic;  
52.             TextView phone_function_name;  
53.         }  
54.         public ImageAdapter(Context c){  
55.             mContext = c;  
56.             inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);  
57.         }  
58.         @Override  
59.         public int getCount() {  
60.             return mFunctionPics.length;  
61.         }  
62.   
63.         @Override  
64.         public Object getItem(int position) {  
65.             return position;  
66.         }  
67.   
68.         @Override  
69.         public long getItemId(int position) {  
70.             return position;  
71.         }  
72.   
73.         @Override  
74.         public View getView(int position, View convertView, ViewGroup parent) {  
75.             GirdTemp temp;  
76.             if(convertView == null){  
77.                 convertView = inflater.inflate(R.layout.gridview_item, null);  
78.                 temp = new GirdTemp();  
79.                 temp.phone_function_pic = (ImageView) convertView.findViewById(R.id.function_view);  
80.                 temp.phone_function_name = (TextView) convertView.findViewById(R.id.function_name);  
81.                 convertView.setTag(holder);  
82.             }else{  
83.                 temp = (GirdHolder) convertView.getTag();  
84.             }  
85.             temp.phone_function_pic.setImageResource(mFunctionPics[position]);  
86.             temp.phone_function_name.setText(mFunctionName[position]);  
87.             return convertView;  
88.         }  
89.           
90.     }  
91.   
92. }  

girdview_main.xml代码如下：

1. <?xml version="1.0" encoding="utf-8"?>  
2. <GridView xmlns:android="http://schemas.android.com/apk/res/android"   
3.     android:id="@+id/gridview"  
4.     android:layout_width="fill_parent"   
5.     android:layout_height="fill_parent"  
6.     android:numColumns="auto_fit"  //自动适应多少行
7.     android:verticalSpacing="20dp"  //两行之间的距离
8.     android:horizontalSpacing="20dp"  //两列之间的距离
9.     android:gravity="center"  
10. /> 

girdview_item.xml源码：

1. <?xml version="1.0" encoding="utf-8"?>  
2. <RelativeLayout   
3.         xmlns:android="http://schemas.android.com/apk/res/android"   
4.  android:layout_height="wrap_content" 
5. android:layout_width="fill_parent" 
6.          <ImageView>   
7.                 android:layout_width="wrap_content"
8. android:layout_height="wrap_content"
9. android:id="@+id/function_view"
10. android:layout_centerHorizontal="true"
11. </ImageView> 
12.          <TextView   
13.                android:layout_width="wrap_content"   
14.                android:layout_below="@+id/function_view"   
15.                android:layout_height="wrap_content"   
16.                android:layout_centerHorizontal="true"   
17.                android:id="@+id/function_name">  
18.          </TextView>  
19. </RelativeLayout>  

 2.跟ListView类似的数据绑定方式
