我需要获得本月的周六和周日（比如说：8月），但我得到的结果是上个月，即7月。

Answer 1

请改为尝试：

List<Date> disable = new ArrayList<>();

Calendar cal = Calendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, 1);
int month = cal.get(Calendar.MONTH);
do {
    int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);
    if (dayOfWeek == Calendar.SATURDAY || dayOfWeek == Calendar.SUNDAY)
        disable.add(cal.getTime());
    cal.add(Calendar.DAY_OF_MONTH, 1);
} while (cal.get(Calendar.MONTH) == month);

SimpleDateFormat fmt = new SimpleDateFormat("EEE M/d/yyyy");
for (Date date : disable)
    System.out.println(fmt.format(date));

输出

Sat 8/6/2016
Sun 8/7/2016
Sat 8/13/2016
Sun 8/14/2016
Sat 8/20/2016
Sun 8/21/2016
Sat 8/27/2016
Sun 8/28/2016

Answer 2

public static  ArrayList<Calendar> getAllSundayDate(Calendar aCurrentDateCal, int aMaxMonth){
    //max month next month for Exp: next 2 month from this month
    ArrayList<Calendar> disableDayList = new ArrayList<>();
    Calendar cal;
    cal = aCurrentDateCal;
    for (int index = 0; index < aMaxMonth; index++) {
        int year = cal.get(Calendar.YEAR);
        int month = cal.get(Calendar.MONTH);
        Calendar curCal = Calendar.getInstance();
        curCal.set(year, month , 1);
        int daysInMonth = curCal.getActualMaximum(Calendar.DAY_OF_MONTH);

        for (int day = 1; day <= daysInMonth; day++) {
            curCal.set(year, month, day);
            int dayOfWeek = curCal.get(Calendar.DAY_OF_WEEK);
            if (dayOfWeek == Calendar.SATURDAY || dayOfWeek == Calendar.SUNDAY) {
                disableDayList.add(curCal);
                Date curDate = new Date(curCal.getTimeInMillis());
                System.out.println(curDate);
            }
        }

        cal.add(Calendar.MONTH, 1);
    }
    return disableDayList;
}

如何在android中找到当月的周六和周日？
