你说的是这样子么？[img]http://dl.iteye.com/upload/picture/pic/84063/264896a3-f973-31c3-892e-76eddb4fe088.jpg[/img]
如果是这样子的话就看源码吧：
gridview.xml
[code="xml"]<?xml version="1.0" encoding="utf-8"?>
android:id="@+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:columnWidth="90dp"
android:stretchMode="columnWidth"
android:gravity="center"
/>[/code]
item.xml
[code="xml"]<?xml version="1.0" encoding="utf-8"?>
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:paddingBottom="4dip"
>
android:id="@+id/ItemImage"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_centerHorizontal="true"
/>
android:id="@+id/ItemText"
android:layout_width="wrap_content"
android:layout_below="@+id/ItemImage"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="TextView01"
/>
[/code]
activity
[code="java"]package com.test;

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

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.GridView;
import android.widget.SimpleAdapter;

public class TestGridView extends Activity {
private GridView gridview;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.gridview);

    gridview = (GridView) findViewById(R.id.gridview);

    // 生成动态数组，并且转入数据
    ArrayList<HashMap<String, Object>> lstImageItem = new ArrayList<HashMap<String, Object>>();
    for (int i = 0; i < 10; i++) {
        HashMap<String, Object> map = new HashMap<String, Object>();
        map.put("ItemImage", R.drawable.icon);// 添加图像资源的ID
        map.put("ItemText", "NO." + String.valueOf(i));// 按序号做ItemText
        lstImageItem.add(map);
    }
    // 生成适配器的ImageItem <====> 动态数组的元素，两者一一对应
    SimpleAdapter saImageItems = new SimpleAdapter(this, // 没什么解释
            lstImageItem,// 数据来源
            R.layout.item,// night_item的XML实现
            // 动态数组与ImageItem对应的子项
            new String[] { "ItemImage", "ItemText" },
            // ImageItem的XML文件里面的一个ImageView,两个TextView ID
            new int[] { R.id.ItemImage, R.id.ItemText });
    // 添加并且显示
    gridview.setAdapter(saImageItems);
    // 添加消息处理
    gridview.setOnItemClickListener(new ItemClickListener());
}

// 当AdapterView被单击(触摸屏或者键盘)，则返回的Item单击事件
class ItemClickListener implements OnItemClickListener {
    public void onItemClick(AdapterView<?> arg0,// The AdapterView where the click happened
            View arg1,// The view within the AdapterView that was clicked
            int arg2,// The position of the view in the adapter
            long arg3// The row id of the item that was clicked
    ) {
        // 在本例中arg2=arg3
        @SuppressWarnings("unchecked")
        HashMap<String, Object> item = (HashMap<String, Object>) arg0.getItemAtPosition(arg2);
        // 显示所选Item的ItemText
        setTitle((String) item.get("ItemText"));
    }
}
