　　如下代码直接复制到项目就可以运行使用了。我们都知道，android的九宫格可以用GridView控件实现，这里首先定义一个

　　gridview.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical" ><GridViewandroid:id="@+id/gv_home"android:layout_width="match_parent"android:layout_height="match_parent"android:numColumns="3" ></GridView></LinearLayout>

　　接着还得在定义一个gridview_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:gravity="center"android:orientation="vertical" ><ImageView android:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/iv_icon"android:src="@drawable/ic_launcher"/><TextView android:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/tv_title"android:text="模块标题"android:textSize="18sp"/></LinearLayout>

　　那么现在布局就实现了，接下来就是Android代码了。这里需要注意的就是不能缺少GridView适配器。

　　

public class MainActivity extends Activity {private GridView gv_home;private String[] mTitleStrs;private int[] mDrawableIds;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_home);initUI();//初始化数据的方法
        initData();}private void initData() {mTitleStrs = new String[]{"1","2","3","4","5","6","7","8","9"};//注意这里的数字要和下面的图片id一一对应，要不然实现的效果会文字图片不符合mDrawableIds = new int[]{R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher};//九宫格控件设置数据适配器(等同ListView数据适配器)gv_home.setAdapter(new MyAdapter());}class MyAdapter extends BaseAdapter{@Overridepublic int getCount() {return mTitleStrs.length;}@Overridepublic Object getItem(int position) {return mTitleStrs[position];}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {View view = View.inflate(getApplicationContext(), R.layout.gridview_item, null);ImageView iv_icon = (ImageView) view.findViewById(R.id.iv_icon);TextView tv_title = (TextView) view.findViewById(R.id.tv_title);tv_title.setText(mTitleStrs[position]);iv_icon.setBackgroundResource(mDrawableIds[position]);return view;}}private void initUI() {gv_home = (GridView) findViewById(R.id.gv_home);}
}
