String week = "";
       Date today = new Date();
       Calendar calendar = Calendar.getInstance();
       calendar.setTime(today);
       int weekday = calendar.get(Calendar.DAY_OF_WEEK);
       if (weekday == 1) {
           week = "星期日";
       } else if (weekday == 2) {
           week = "星期一";
       } else if (weekday == 3) {
           week = "星期二";
       } else if (weekday == 4) {
           week = "星期三";
       } else if (weekday == 5) {
           week = "星期四";
       } else if (weekday == 6) {
           week = "星期五";
       } else if (weekday == 7) {
           week = "星期六";
       }
