过去的通知与当前通知一起显示

Question

我正在使用AlarmManager 重复警报。我已经为周一、周四和周六设置了重复闹钟。警报在星期一正确显示，但到星期四时，它会同时显示星期一和星期四的两个通知，并在星期六显示所有三个通知。如何进行编码，以便当第一个警报完成时，它不会显示在同一周的后续警报中，而是会显示到接下来的几周？

     }

}

        onStartCommand(intent, 0, startId);
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        mManager = (NotificationManager) this.getApplicationContext()
                .getSystemService(
                        this.getApplicationContext().NOTIFICATION_SERVICE);

        Intent intent1 = new Intent(this.getApplicationContext(),
                TheBeginning1English.class);
        if (currentapiVersion < android.os.Build.VERSION_CODES.HONEYCOMB) {
            Notification notification = new Notification(
                    R.drawable.ic_launcher,
                    "Its Sunday!.",

                    | Intent.FLAG_ACTIVITY_CLEAR_TOP);

            PendingIntent pendingNotificationIntent1 = PendingIntent
                    .getActivity(this.getApplicationContext(), 0, intent1,
                            PendingIntent.FLAG_UPDATE_CURRENT);
            notification.flags |= Notification.FLAG_AUTO_CANCEL;
            notification.setLatestEventInfo(this.getApplicationContext(),
                    "Testing", "Its Sunday.",
                    pendingNotificationIntent1);

            mManager.notify(0, notification);
        } else {
            PendingIntent pendingNotificationIntent1 = PendingIntent
                    .getActivity(this.getApplicationContext(), 0, intent1,
                            PendingIntent.FLAG_UPDATE_CURRENT);
            Notification notification = new NotificationCompat.Builder(this)
                    .setContentTitle("Test Test App")
                    .setContentText("Its Sunday!.")
                    .setWhen(System.currentTimeMillis())
                    .setContentIntent(pendingNotificationIntent1)

        }

    }

    @Override
    public void onDestroy() {
        // TODO Auto-generated method stub
        super.onDestroy();
    }

}

就是这样，在主活动中，您将看到四个单独的日历变量，我必须创建一个 Receiver、Receiver1、Receiver2、Receiver3 和 AlarmService1、2、3。对于每个日历，不是最好的方法，而是我能想到的唯一方法。我添加了：

Date now = new Date(System.currentTimeMillis());
if (calendar3.getTime().before(now)) {
    calendar3.add(Calendar.MONTH, 1);
} else if (calendar.getTime().before(now)) {
    calendar.add(Calendar.HOUR, 168);
} else if (calendar1.getTime().before(now)) {
    calendar1.add(Calendar.HOUR, 168);
} else if (calendar2.getTime().before(now)) {
    calendar2.add(Calendar.HOUR, 168);
}

我今天添加了日期部分，还没有检查它是否会起作用。感谢您帮我解决这个问题！

Alaram 服务如何工作？

它会根据您的情况开始，就像您为一天、一周或任何工作日设置的一样。所以在每个指定的时间设置它接收命令。比如通知，音调。

所以在 onStartServiceCommand() 方法中。你必须为此应用逻辑。

所以通知只针对特定的一天发出一次。
