Android日历获取当前星期几作为字符串

2022-01-11 00:00:00 null calendar dayofweek android java

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:

i tried to get a string with the name of the actual weekday this way:

            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)

but weekDay stays always null and i actually have no idea why because the debugger says that dayOfWeek is 5 so i should be equal to c.get(Calendar.THURSDAY)

推荐答案

就这么简单

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