如何设置一定天数的定期闹钟，例如每27天或15天

    switch (reminder.getRepeatType()) {
        case Reminder.HOURLY:
            calendar.add(Calendar.HOUR, reminder.getInterval());
            break;
        case Reminder.DAILY:
            calendar.add(Calendar.DATE, reminder.getInterval());
            break;
        case Reminder.WEEKLY:
            calendar.add(Calendar.WEEK_OF_YEAR, reminder.getInterval());
            break;
        case Reminder.MONTHLY:
            calendar.add(Calendar.MONTH, reminder.getInterval());
            break;
        case Reminder.YEARLY:
            calendar.add(Calendar.YEAR, reminder.getInterval());
            break;

Answer 1

The API is 
// Hopefully your alarm will have a lower frequency than this!
alarmMgr.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
        AlarmManager.INTERVAL_HALF_HOUR,
        AlarmManager.INTERVAL_HALF_HOUR, alarmIntent);

Answer 2

这是一个触发重复broadcastReceiver的简单示例代码：

public static void setRepeaterAlarm(Context context, Class<?> cls, long afterTimeMillis, long intervalTimeMillis) {
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(context, cls);
    PendingIntent pendIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    long triggerAtTime = SystemClock.elapsedRealtime() + afterTimeMillis;
    alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, triggerAtTime, intervalTimeMillis, pendIntent);
}
