解决方案
你说的是这样子么？如果是这样子的话就看源码吧：gridview.xml<?xml version="1.0" encoding="utf-8"?><GridView xmlns:android="http://schemas.android.com/apk/res/android"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" />item.xml<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_height="wrap_content"android:layout_width="fill_parent"android:paddingBottom="4dip"><ImageViewandroid:id="@+id/ItemImage"android:layout_height="wrap_content"android:layout_width="wrap_content"android:layout_centerHorizontal="true"/><TextViewandroid: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"/></RelativeLayout>activitypackage 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IDmap.put("ItemText", "NO." + String.valueOf(i));// 按序号做ItemTextlstImageItem.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 IDnew 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 happenedView arg1,// The view within the AdapterView that was clickedint arg2,// The position of the view in the adapterlong 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ItemTextsetTitle((String) item.get("ItemText"));}}}
