如何在Android AlarmManager中安排未来的重复报警？

我能够使用以下代码在Android中设置重复警报。然而，问题是它也会立即发出通知，我不希望这样。我只想让用户输入他们希望闹钟在什么时候响的时间，让闹钟在那个时候响，然后在指定的时间间隔内重复。我尝试切换已运行的实时唤醒而不是RTC唤醒，但是该代码对我不起作用

public static long getTimeForNotification(int hour, int minutes, int am_pm){
    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR, hour);
    calendar.set(Calendar.MINUTE, minutes);
    calendar.set(Calendar.AM_PM, am_pm);
    return  calendar.getTimeInMillis();
}

public static PendingIntent createNotificationPendingIntent(
        String name,
        String number,
        String messageArrayListString,
        String contactID,
        String photo_uri,
        String actionType,
        Context mContext
        ){

    Intent alertIntent = new Intent(mContext, AlertReceiver.class);
    alertIntent.putExtra("name", name);
    alertIntent.putExtra("number", number);
    alertIntent.putExtra("messageList", messageArrayListString);
    alertIntent.putExtra("contactID", contactID.toString());
    alertIntent.putExtra("photo_uri", photo_uri);
    alertIntent.setAction(actionType);


    PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext, Integer.parseInt(contactID.toString()), alertIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    return pendingIntent;
}

public static void createNotifications(PendingIntent notificationPendingIntent, Context mContext, Long alarmTime, int frequencyMultiplier){

    AlarmManager alarmManager = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime, AlarmManager.INTERVAL_DAY * Long.valueOf(frequencyMultiplier), notificationPendingIntent);

}

提前感谢

这就是我所用的

public class AlarmHelper {
    private static final String TAG = "AlarmHelper";
    private static final int REQUEST_CODE = 12377;
    private static final int REQUEST_CODE_OVERTIME = 12376;

    private AlarmHelper() {
    }

    public static void scheduleAlarm(Context c) {
        AlarmManager manager = (AlarmManager) c.getSystemService(Context.ALARM_SERVICE);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(c, REQUEST_CODE, new Intent(c, ClockInBroadcastReceiver.class), PendingIntent.FLAG_CANCEL_CURRENT);


        //Set next clock-in time
        GregorianCalendar time = new GregorianCalendar();
        time.add(...,...); //Whatever you want to add.


        if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
            manager.set(AlarmManager.RTC_WAKEUP, time.getTimeInMillis() + 1000, pendingIntent);
        } else if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
            manager.setExact(AlarmManager.RTC_WAKEUP, time.getTimeInMillis() + 1000, pendingIntent);
        } else {
            manager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, time.getTimeInMillis() + 1000, pendingIntent);
        }

    }

}

这对您有帮助吗？
