在android中计算给定两个日期（不包括周末）的日期

嗨，我是android的新手，在我的应用程序中，我必须从“当前”日期中“减去”给定日期，这很有效

这里我的主要要求是，我不应该计算周末（如周日和周六，公共假日），除了周末，我必须从“当前”日期中“减去”给定日期

请帮我拿一个

我的代码：-

排除周末的想法是使用：

if (startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SATURDAY &&  startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY) {
            ++workDays;
        }

使用此功能：

public static int countWorkingDate(Date dateStart, Date dateStop) {
    Calendar startCal = Calendar.getInstance();
    startCal.setTime(dateStart);

    Calendar endCal = Calendar.getInstance();
    endCal.setTime(dateStop);

    int workDays = 0;

    //Return 0 if start and end are the same
    if (startCal.getTimeInMillis() == endCal.getTimeInMillis()) {
        return 0;
    }

    if (startCal.getTimeInMillis() > endCal.getTimeInMillis()) {
        startCal.setTime(dateStop);
        endCal.setTime(dateStart);
    }

    do {
        //excluding start date
        startCal.add(Calendar.DAY_OF_MONTH, 1);
        if (startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SATURDAY && startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY) {
            ++workDays;
        }
    } while (startCal.getTimeInMillis() < endCal.getTimeInMillis()); //excluding end date

    return workDays;
}

结果是：

I/System.out:6

我希望它能有所帮助。
