可以使用不同的通知ID来区分前台服务通知和其他通知。示例代码如下：

private static final int NOTIFICATION_ID_SERVICE = 1;
private static final int NOTIFICATION_ID_ACTION = 2;

private void startForeground() {
    // Create a notification channel for the service notification.
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel serviceChannel = new NotificationChannel(
                NOTIFICATION_CHANNEL_ID,
                "Foreground Service Channel",
                NotificationManager.IMPORTANCE_DEFAULT
        );
        NotificationManager manager = getSystemService(NotificationManager.class);
        manager.createNotificationChannel(serviceChannel);
    }

    // Create the notification for the foreground service.
    Notification notification = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
            .setContentTitle("My Foreground Service")
            .setContentText("Running...")
            .setSmallIcon(R.drawable.ic_notification)
            .build();

    // Start the service in the foreground with the notification.
    startForeground(NOTIFICATION_ID_SERVICE, notification);
}

private void showActionNotification() {
    // Create the notification for an action.
    Notification notification = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
            .setContentTitle("Action Notification")
            .setContentText("Something happened...")
            .setSmallIcon(R.drawable.ic_notification)
            .build();

    // Show the notification.
    NotificationManagerCompat manager = NotificationManagerCompat.from(this);
    manager.notify(NOTIFICATION_ID_ACTION, notification);
}

在这个示例中，我们创建了两个不同的通知ID：NOTIFICATION_ID_SERVICE和NOTIFICATION_ID_ACTION，其中NOTIFICATION_ID_SERVICE用于启动前台服务时显示的通知，而NOTIFICATION_ID_ACTION用于其他通知。

当我们需要显示前台服务通知时，我们调用startForeground()方法，并传递NOTIFICATION_ID_SERVICE和前台服务通知的内容。

当我们需要显示其他通知时，我们调用showActionNotification()方法，并传递NOTIFICATION_ID_ACTION和其他通知的内容。

使用不同的通知ID可以确保前台服务通知和其他通知
