周期性闹钟设置的常见Bug解决

 

 long compareTime(long triggerAtTime, long now) {
  if (triggerAtTime <= now) {
   triggerAtTime += AlarmManager.INTERVAL_DAY * 7;//如果当前设置的触发时间小于、等于现在的时间，就让它在下一个星期响起来。
  }
  return triggerAtTime;
 }

void setAlarm(AlarmManager alarmManager, long triggerAtMillis,
   long intervalMillis, PendingIntent pendingIntent) {
  alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, triggerAtMillis,
    intervalMillis, pendingIntent);
 }
