如何在Android上用自己的通知替换firebase通知？

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // 获取Firebase通知的内容和其他相关信息
        String title = remoteMessage.getNotification().getTitle();
        String body = remoteMessage.getNotification().getBody();

        // 构建自定义通知
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channel_id")
                .setSmallIcon(R.drawable.notification_icon)
                .setContentTitle(title)
                .setContentText(body)
                .setPriority(NotificationCompat.PRIORITY_DEFAULT)
                .setAutoCancel(true);

        // 显示自定义通知
        NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
        notificationManager.notify(1, builder.build());
    }
}
