android - Cannot call this method while RecyclerView is computing a layout or scrolling when try remove item from recyclerview

I am Trying to remove my item from recyclerview, but i always getting error

java.lang.IllegalStateException: Cannot call this method while RecyclerView is computing a layout or scrolling

i am using notify datasetchanged, can i solve this?

public class AdapterIntransit extends RecyclerView.Adapter<AdapterIntransit.ViewHolder> {
    private Context context;
    List<DataIntransit> data;

    public AdapterIntransit(Context context, List<DataIntransit> data) {
        this.context = context;
        this.data = data;
    }

    @Override
    public AdapterIntransit.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardintransit, parent, false);
        return new ViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(AdapterIntransit.ViewHolder holder, int position) {
        if (data.get(position).getJml1() - data.get(position).getJml2() <= 0) {
            data.remove(position);
            notifyItemRemoved(position);
            notifyItemRangeChanged(position, getItemCount());
            notifyDataSetChanged();
        } else {
            holder.kode.setText(data.get(position).getKode());
            holder.nama.setText(data.get(position).getNama());
            holder.jumlah.setText(String.valueOf(data.get(position).getJml1() - data.get(position).getJml2()));
        }
    }

    @Override
    public int getItemCount() {
        return data.size();
    }
    public class ViewHolder extends RecyclerView.ViewHolder{
        TextView kode, nama, jumlah;
        public ViewHolder(View itemView) {
            super(itemView);
            kode = (TextView)itemView.findViewById(R.id.kode);
            nama = (TextView)itemView.findViewById(R.id.nama);
            jumlah = (TextView)itemView.findViewById(R.id.jumlah);

        }
    }
}

Below answer worked for me

This is just workaround for the problem.

This usually occurs when you are calling notifyDataSetChanged() on the background thread. So just move notify to UI thread

recyclerView.post(new Runnable()
            {
              @Override
              public void run() {
                myadapter.notifyDataSetChanged();
              }
            });

You use your RecyclerView instance and inside the post method a new Runnable added to the message queue. The runnable will be run on the user interface thread. This is a limit for Android to access the UI thread from background (e.g. inside a method which will be run in a background thread). for more you run it on UI thread if you needed.

For more you can run it on UI thread, if you needed

 runOnUiThread(new Runnable(){
 public void run() {
      // UI code goes here
 }
 });
