Android的日历得到一周的当前日期作为字符串 [英] Android Calendar get current day of week as string

问题描述

我试图得到一个字符串与实际工作日的名字是这样的：

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";

但平日停留总是空，我居然不知道为什么，因为调试说一周中的某天 5这样我应该等于 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

我做做到了这一点如下：

I accomplished this by doing the following:

String weekDay;
SimpleDateFormat dayFormat = new SimpleDateFormat("EEEE", Locale.US);

Calendar calendar = Calendar.getInstance();
weekDay = dayFormat.format(calendar.getTime());

• 使用天格式EEEE将返回完整星期名称，如周二
• 使用天格式E将返回缩写名称，即星期二
• 的另一个好处返回此格式的Andr​​oid是基于区域设置，将翻译工作日。

您将要审查的SimpleDateFormat 了解详情。我觉得这是最干净的方法中，你不需要开关或如果语句，如果你唯一需要的是得到的字符串值。

You will want to review the SimpleDateFormat to learn more. I think this is the cleanest approach in that you do not need a switch or if statement if your only need is to get the string value.
