GridView 動態添加一個view(加號表徵圖)，資料等於9的時候，加號表徵圖隱藏_gridview

    class MySelectPic extends BaseAdapter {        @Override        public int getCount() {//            if (resul.size() == 9) {//                return resul.size();//            } else {                return resul.size() + 1;//            }        }        @Override        public Object getItem(int i) {            return resul.get(i);        }        @Override        public long getItemId(int i) {            return i;        }        @Override        public View getView(int position, View view, ViewGroup viewGroup) {            ViewHolder viewHolder = null;            if (view == null) {                viewHolder = new ViewHolder();                view = getLayoutInflater().inflate(R.layout.griditem, viewGroup, false);                viewHolder.addimage = (ImageView) view.findViewById(R.id.additem);                view.setTag(viewHolder);            } else {                viewHolder = (ViewHolder) view.getTag();            }            if (position == resul.size()) {                //加號表徵圖                viewHolder.addimage.setImageBitmap(BitmapFactory.decodeResource(getResources(), R.mipmap.android_icon_addpic_focused));                if (position == 9) {                    viewHolder.addimage.setVisibility(View.GONE);                }            } else {                                //原先的正常資料的顯示，操作等                Glide.with(FirstActivity.this)                        .load(resul.get(position))                        .placeholder(R.drawable.global_img_default)                        .centerCrop()                        .into(viewHolder.addimage);            }return  view;        }        class ViewHolder {            ImageView addimage;        }    }
