java测试代码：

package com.example.gridview;import java.util.ArrayList;import java.util.HashMap;import android.app.Activity;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.graphics.Matrix;import android.os.Bundle;import android.view.Display;import android.view.Menu;import android.view.MenuItem;import android.view.MotionEvent;import android.widget.GridView;import android.widget.ImageView;import android.widget.SimpleAdapter;public class MainActivity extends Activity {private ArrayList<HashMap<String, Object>> data;private String[] iconName = { "通讯录", "日历", "照相机", "时钟", "游戏", "短信", "铃声", "设置", "语音", "天气", "浏览器", "视频" };@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);data = new ArrayList<HashMap<String, Object>>();for (int i = 0; i < iconName.length; i++) {HashMap<String, Object> map = new HashMap<String, Object>();map.put("image", R.drawable.ic_launcher);map.put("icon", iconName[i]);data.add(map);}GridView mGridView = (GridView) findViewById(R.id.gridview);String[] from = { "image", "icon" };int[] resource = { R.id.image, R.id.text };mGridView.setAdapter(new SimpleAdapter(this, data, R.layout.item, from, resource));}}

需要的activity_main.xml：

<LinearLayout 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="com.example.gridview.MainActivity" >    <!-- numColumns列数设置为自动     columnWidth每列的宽度，也就是Item的宽度    stretchMode缩放与列宽大小同步    -->    <GridView        android:id="@+id/gridview"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:columnWidth="80dp"        android:numColumns="auto_fit"        android:stretchMode="columnWidth" >    </GridView></LinearLayout>

需要的item.xml:

<LinearLayout 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"    android:orientation="vertical"    android:padding="10dp"    android:gravity="center"    tools:context="com.example.gridview.MainActivity" >  <ImageView       android:id="@+id/image"      android:layout_width="60dp"      android:layout_height="60dp"      android:src="@drawable/ic_launcher"/>    <TextView       android:id="@+id/text"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_marginTop="5dp"      android:text="文字"/></LinearLayout>
