我试图以这种方式获取一个带有实际工作日名称的字符串:

            Calendar c = Calendar.getInstance();
            int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);

            if (c.get(Calendar.MONDAY) == dayOfWeek) weekDay = "monday";
            else if (c.get(Calendar.TUESDAY) == dayOfWeek) weekDay = "tuesday";
            else if (c.get(Calendar.WEDNESDAY) == dayOfWeek) weekDay = "wednesday";
            else if (c.get(Calendar.THURSDAY) == dayOfWeek) weekDay = "thursday";
            else if (c.get(Calendar.FRIDAY) == dayOfWeek) weekDay = "friday";
            else if (c.get(Calendar.SATURDAY) == dayOfWeek) weekDay = "saturday";
            else if (c.get(Calendar.SUNDAY) == dayOfWeek) weekDay = "sunday";

但 weekDay 始终为空，我实际上不知道为什么，因为调试器说 dayOfWeek 是 5，所以我应该等于 c.get( Calendar.THURSDAY)

就这么简单

sCalendar = Calendar.getInstance();
String dayLongName = sCalendar.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.LONG, Locale.getDefault());
