AlarmManager调度

我正试着安排我的报警经理在一天中每小时都要启动一个意图。 我就是这么做的,但效果不太好。

代码:

 new code after edit:


          Calendar cal = Calendar.getInstance();
    cal.set(Calendar.HOUR_OF_DAY , 22); //22:00 of every evening
    cal.set(Calendar.MINUTE , 0); //initiate minute time
    cal.set(Calendar.SECOND , 0);
    cal.add(Calendar.MINUTE, randomMinutes); //adding mintues so we get random time btw 22:00-07:00
    cal.add(Calendar.DAY_OF_YEAR, 1); //switching to the next day.



    am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
            AlarmManager.INTERVAL_DAY, pi);

随机分钟是从0到600的数字

谢谢,

雷。
