        @Override
        protected void onPostExecute(String result) {
            // TODO Auto-generated method stub
            super.onPostExecute(result);
            pDialog.dismiss();
            go();
        }

    }

}

所以我想记录所有操作菜单项。并想知道如何使用 res.drawable 中的 drawable 设置操作菜单项图标

我不知道该尝试什么，谢谢
