android 自定义布局的Notification 卡顿？

安卓6.0的，写一个播放器，想要把Notification改成普通音乐播放器的样子。
状态栏下拉上划整个都非常卡。。。

  private void sendCustomerNotification(int command){
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        builder.setContentTitle("Notification");
        builder.setContentText("S.M.Player  请点击进入播放界面");
        builder.setSmallIcon(R.mipmap.ic_launcher);
        //builder.setLargeIcon(BitmapFactory.decodeResource(getResources(),R.drawable.push));
        builder.setAutoCancel(false);
        builder.setOngoing(true);
        builder.setShowWhen(false);
        RemoteViews remoteViews = new RemoteViews(getPackageName(),R.layout.notify);
        remoteViews.setTextViewText(R.id.title,"Notification");
        remoteViews.setTextViewText(R.id.text,"song"+"index");
//        if(command==CommandNext){
//            remoteViews.setImageViewResource(R.id.btn1,R.drawable.ic_pause_white);
//        }else if(command==CommandPlay){
//            if(playerStatus==StatusStop){
//                remoteViews.setImageViewResource(R.id.btn1,R.drawable.ic_pause_white);
//            }else{
//                remoteViews.setImageViewResource(R.id.btn1,R.drawable.ic_play_arrow_white_18dp);
//            }
//        }
        Intent Intent1 = new Intent(this,MusicplayerActivity.class);
        Intent1.putExtra("command",1);
        //getService(Context context, int requestCode, @NonNull Intent intent, @Flags int flags)
        //不同控件的requestCode需要区分开 getActivity broadcoast同理
        PendingIntent PIntent1 =  PendingIntent.getService(this,5,Intent1,0);
        remoteViews.setOnClickPendingIntent(R.id.notifyplaying,PIntent1);

        Intent Intent2 = new Intent(this,MusicplayerActivity.class);
        Intent2.putExtra("command",2);
        PendingIntent PIntent2 =  PendingIntent.getService(this,6,Intent2,0);
        remoteViews.setOnClickPendingIntent(R.id.notifynextsong,PIntent2);

        Intent Intent3 = new Intent(this,MusicplayerActivity.class);
        Intent3.putExtra("command",3);
        PendingIntent PIntent3 =  PendingIntent.getService(this,7,Intent3,0);
        remoteViews.setOnClickPendingIntent(R.id.notifypresong,PIntent3);

        builder.setContent(remoteViews);
        Notification notification = builder.build();
        notificationManager.notify(8,notification);
    }
