  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";
