            //1、inflate一个view布局
            View view = View.inflate(getApplicationContext(), R.layout.grid_home_item, null);

            // 2、找到该布局里面的空间imageview和textview
            ImageView iv_icon = (ImageView) view.findViewById(R.id.iv_icon_item);
            TextView tv_name = (TextView) view.findViewById(R.id.tv_name_item);

            // 3、填充iamge和text
            iv_icon.setImageResource(icons[position]);
            tv_name.setText(names[position]);

            return view;
        }

        @Override
        public Object getItem(int position) {
