如何获取当前日期之前的最后一个星期日？ [英] How to get the last Sunday before current date?

问题描述

我有以下代码用于获取当前日期之前的最后一个星期日：

I have the following code for getting the last Sunday before the current date:

Calendar calendar=Calendar.getInstance();
calendar.set(Calendar.WEEK_OF_YEAR, calendar.get(Calendar.WEEK_OF_YEAR)-1);
calendar.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);
Log.e("first day", String.valueOf(calendar.get(Calendar.DAY_OF_MONTH)));

但是这个代码不工作。请告诉我，我该如何解决？

But this code doesn't work. Please, tell me, how can I fix it?

推荐答案

这将工作。我们首先得到日计数，然后减去当前日，并添加1（星期日）

This will work. We first get the day count, and then subtract that with the current day and add 1 ( for sunday)

Calendar cal=Calendar.getInstance();
cal.add( Calendar.DAY_OF_WEEK, -(cal.get(Calendar.DAY_OF_WEEK)-1)); 
System.out.println(cal.get(Calendar.DATE));
