布局activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context=".MainActivity" >    <GridView        android:id="@+id/gridView1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentLeft="true"        android:layout_alignParentTop="true"        android:numColumns="3" ><!-- 列数  -->    </GridView></RelativeLayout>

MainActivity.java

package com.yqy.yqy_gridviewtest;import java.util.ArrayList;import java.util.HashMap;import android.app.Activity;import android.os.Bundle;import android.view.Menu;import android.view.View;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.GridView;import android.widget.SimpleAdapter;import android.widget.Toast;public class MainActivity extends Activity {GridView gridview;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);gridview = (GridView) findViewById(R.id.gridView1);initGridView();}private void initGridView() {// 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 < 9; i++) {HashMap<String, Object> map = new HashMap<String, Object>();map.put("tv", i+1);// 按序号做imglstImageItem.add(map);}SimpleAdapter sa = new SimpleAdapter(this, lstImageItem,R.layout.item_gridview, new String[] { "tv" },new int[] { R.id.tv });gridview.setAdapter(sa);gridview.setOnItemClickListener(new ItemClickListener());}class ItemClickListener implements OnItemClickListener {@Overridepublic void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {@SuppressWarnings("unchecked")HashMap<String, Object> item = (HashMap<String, Object>) arg0.getItemAtPosition(arg2);int index = (Integer) item.get("tv");Toast.makeText(MainActivity.this, "点击："+index, Toast.LENGTH_SHORT).show();}}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}}

item_gridview.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <TextView        android:id="@+id/tv"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerHorizontal="true"        android:layout_centerVertical="true"        android:text="TextView" /></RelativeLayout>

这就ok了，如果想要图片文字并存，修改item_gridview.xml ok了
