利用GridView实现手机菜单功能

最近刚学习Andrioid 开发,昨日看到大牛级网友hellgv写的关于《Android入门第八篇之GridView(九宫图)》之后想到做一个模仿手机菜单界面的布局,于是有了今天下面的入门级作品,这个作品与大牛级网友hellgv写的作品最大的区别就是在菜单图片下面添加了不同文字,希望大家能多提建议,看怎么实现布局更加精美,共同勉励,共同进步,废话少说,先看效果图:

  public class AndroidTest2_3_3 extends Activity {          private static final String TAG = "AndroidTest2_3_3";       private Bitmap bit;         private String textArray1[] = {"婺源", "丹霞山", "周庄"};         private String textArray2[] = {"油菜花盛开的地方", "红绿之间,雄壮与温柔", "梦中的水乡"};                     /** Called when the activity is first created。 */         @Override         public void onCreate(Bundle savedInstanceState) {            super.onCreate(savedInstanceState);               setContentView(R。layout。main);                        String imagepath = Environment。getExternalStorageDirectory() + "/abc。jpg";             bit = BitmapFactory。decodeFile(imagepath);                             GridView gv=(GridView)this。findViewById(R。id。GridView01);                Log。d(TAG, "+++++++++++1");             ImageAdapter ia = new ImageAdapter(this);             gv。setAdapter(ia);//为GridView设置数据适配器                       }         /**         * GridView适配器类,创建单元格view         * @author ameyume         *         */           public class ImageAdapter extends BaseAdapter {             private Context mContext;             public ImageAdapter(Context context) {                 Log。d(TAG, "ImageAdapter 1");                 mContext = context;               }          public int getCount() {                  return textArray1。length;               }                        public Object getItem(int position) {                 return position;             }            public long getItemId(int position) {                   return position;             }          public View getView(int position, View convertView, ViewGroup parent) {                   Log。d(TAG, "000000000000000");                   View view = View。inflate(AndroidTest2_3_3。this, R。layout。grid_row, null);                   RelativeLayout rl = (RelativeLayout)view。findViewById(R。id。rlGridRow);                   ImageView image = (ImageView)rl。findViewById(R。id。imageView01);                   image。setImageBitmap(bit);                   TextView tv1 = (TextView)rl。findViewById(R。id。txtLink1);                   tv1。setText(textArray1[position]);
