设置重复规则：

//用RFC5545格式表示的事件持续时间，例如“PT1H”表示事件持续1小时的状态， “P2W”指明2周的持续时间。String duration = "P" + DateUtils.countSecondBetweenTwoDates(schedule.getStartTime(), schedule.getEndTime()) + "S";

int repeat = Integer.parseInt(schedule.getRepeat());  // 重复周期

switch (repeat) {    // 每天    case ScheduleConstants.REPEAT_CYCLE_DAILY:        event.put(CalendarContract.Events.RRULE, "FREQ=DAILY;UNTIL=" + until + ";WKST=SU");        break;    // 每周    case ScheduleConstants.REPEAT_CYCLE_WEEKLY:        event.put(CalendarContract.Events.RRULE, "FREQ=WEEKLY;UNTIL=" + until + ";WKST=SU");        break;    // 每两周    case ScheduleConstants.REPEAT_CYCLE_TWO_WEEKLY:        event.put(CalendarContract.Events.RRULE, "FREQ=WEEKLY;INTERVAL=2;UNTIL=" + until + ";WKST=SU");        break;    // 每月    case ScheduleConstants.REPEAT_CYCLE_MONTHLY:        event.put(CalendarContract.Events.RRULE, "FREQ=MONTHLY;UNTIL=" + until + ";WKST=SU");        break;    // 每年    case ScheduleConstants.REPEAT_CYCLE_YEARLY:        event.put(CalendarContract.Events.RRULE, "FREQ=YEARLY;UNTIL=" + until + ";WKST=SU");        break;    default:        break;}event.put(CalendarContract.Events.DURATION, duration);event.put(CalendarContract.Events.DTEND, (byte[]) null);
/** * 计算两个日期之间的秒数 * @param startDate * @return 返回秒数 */public static int countSecondBetweenTwoDates(Date startDate,Date endTime) {    long a =startDate.getTime();    long b = endTime.getTime();    int c = (int)((b - a) / 1000);    return c;}
