尝试获取当前星期中的星期一的日期

试试这个 ：

public static Date getFirstDayOfWeekDate() {    Calendar cal = Calendar.getInstance();    cal.set(Calendar.DAY_OF_WEEK, cal.getActualMinimum(Calendar.DAY_OF_WEEK));    Date now = new Date();    cal.setTime(now);    int week = cal.get(Calendar.DAY_OF_WEEK);    return new Date(now.getTime() - 24 * 60 * 60 * 1000 * (week - 1));}
