日历显示错误的开始日在Android？

Question

我使用了以下库作为日历，但它显示的星期的第一天是星期一，我想以星期日开始一天。

我修改了相应的代码，但它仍然显示日期，因此星期一是第一天。

ArrayList<Date> days = new ArrayList<>();

        // Get Calendar object instance
        Calendar calendar = (Calendar) mCalendarProperties.getCurrentDate().clone();

        // Add months to Calendar (a number of months depends on ViewPager position)
        calendar.add(Calendar.MONTH, position);

        // Set day of month as 1
        calendar.set(Calendar.DAY_OF_MONTH, 1);

        // Get a number of the first day of the week
        int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK);

        // Count when month is beginning
        int monthBeginningCell = dayOfWeek + (dayOfWeek == 1 ? 5 : -2);

        // Subtract a number of beginning days, it will let to load a part of a previous month
        calendar.add(Calendar.DAY_OF_MONTH, -monthBeginningCell);

        /*
        Get all days of one page (42 is a number of all possible cells in one page
        (a part of previous month, current month and a part of next month))
         */
        while (days.size() < 42) {
            days.add(calendar.getTime());
            calendar.add(Calendar.DAY_OF_MONTH, 1);
        }

        mPageMonth = calendar.get(Calendar.MONTH) - 1;
        CalendarDayAdapter calendarDayAdapter = new CalendarDayAdapter(this, mContext,
                mCalendarProperties, days, mPageMonth);

        mCalendarGridView.setAdapter(calendarDayAdapter);

试试看：

calendar.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);
