  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
//  设置这个活动的布局文件
  setContentView(R.layout.head);
  GridView gridView = (GridView)findViewById(R.id.gridView1);
//  创建一个与网络视图相关联的BaseAdapter适配器
  BaseAdapter adapter = new BaseAdapter() {

   @Override
   public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageview;
    if(convertView==null){

    // TODO Auto-generated method stub
    return position;
   }

   @Override

    // TODO Auto-generated method stub
    return position;
   }

   @Override
