如何在不同的时间设置多个通知？

Question

这是我的问题：我有通知列表，希望在不同的时间显示它们，但它们同时显示在一起。

第一次调用updateLabel函数：

私有空updateLabel（ArrayList通知实体）{

    int timer = 5000;

    for (int i = 0; i < notificationEntities.size(); i++) {

        Notification notification = addNotification(notificationEntities.get(i));
        scheduleNotification(notificationEntities.get(i).getId(), notification, (long) timer);

        timer += 10000;
    }

}

然后创建通知：

私人通知add NotificationEntity（NotificationEntity）{

    NotificationCompat.Builder notification = new NotificationCompat.Builder(this, default_notification_channel_id)
            .setSmallIcon(R.drawable.ic_baseline_android_24)
            .setContentTitle("Notifications Example")
            .setContentText("This is a test notification for " + notificationEntity.getType() + " with id " + notificationEntity.getId())
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setCategory(NotificationCompat.CATEGORY_REMINDER)
            .setVibrate(new long[]{0, 1000, 1000})
            .setChannelId(NOTIFICATION_CHANNEL_ID);

    return notification.build();
}

然后安排通知：

私有void scheduleNotification（int notificationId、通知通知、长延迟）{

    int requestID = (int) System.currentTimeMillis();

    Intent notificationIntent = new Intent(this, NotificationPublisher.class);

    notificationIntent.putExtra(NotificationPublisher.NOTIFICATION_ID, notificationId);
    notificationIntent.putExtra(NotificationPublisher.NOTIFICATION, notification);

    PendingIntent pendingIntent = PendingIntent
            .getBroadcast(this, requestID, notificationIntent, PendingIntent.FLAG_ONE_SHOT);

    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, delay, pendingIntent);

}

这是我的NotificationPublisher类：

公共类通知Publisher扩展BroadcastRecector{

public static final String NOTIFICATION = "myNotification";
public static final String NOTIFICATION_ID = "myNotification-id";
@Override
public void onReceive(Context context, Intent intent) {


    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = intent.getParcelableExtra(NOTIFICATION);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){

        NotificationChannel channel = new NotificationChannel(ClientHomepage.NOTIFICATION_CHANNEL_ID, "Channel", NotificationManager.IMPORTANCE_HIGH);
        channel.setDescription("This is just notification");
        notificationManager.createNotificationChannel(channel);

    }
    int id = intent.getIntExtra(NOTIFICATION_ID, 0);
    notificationManager.notify(id, notification);
}

我的问题是所有通知同时出现，而不是一个接一个地出现。我尝试过更改requestID，但没有帮助，我也尝试过更改PendingEvent标志，这也没有帮助。希望你有什么建议。

据我所知，您在这行代码中添加了错误的时间

通知ntities.get（i）. getId（），通知，（长）定时器）；

您必须添加系统，而不是（长）计时器。currentTimeinMillis（）计时器它将解决您的问题
