利用GridView实现手机菜单功能

时间:2021-09-14 19:00:27

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:

利用GridView实现手机菜单功能

  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

public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context context) {
Log。d(TAG,

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

   TextView tv2
