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

Question

I am trying to remove an item from listview which is not starting a specific text "Dev". But the application is crashing when I remove an item and refresh the recycler list via notifydatasetChanged(). This question has been already asked and I have seen all the solutions but I can't find a proper solution to this.

EvelistAdapter.java

     public class EvelistAdater extends RecyclerView.Adapter<EvelistAdater.ViewHolder> {
    Context cxt;
    ArrayList<Dbbean> adapterlist;
    int row_index;
    public EvelistAdater(Context cxt, ArrayList<Dbbean> list) {
        adapterlist=list;
        this.cxt=cxt;
        Log.d("LIst count",""+adapterlist.size());
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.scanlistadp, viewGroup, false);
        return  new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, final int position) {

        if(adapterlist.get(position).blename.startsWith("Dev")) {
            holder.tv_country.setText(adapterlist.get(position).blename);

        }else{
            removeAt(position);
        }
    }

    @Override
    public int getItemCount() {
        return adapterlist.size();
    }
    public class ViewHolder extends RecyclerView.ViewHolder{
        TextView tv_country;
        RelativeLayout layout;
        ImageView setting;
        public ViewHolder(View view) {
            super(view);
            tv_country = (TextView)view.findViewById(R.id.tshirtname);
            setting = (ImageView) view.findViewById(R.id.setting);
            layout = (RelativeLayout)view.findViewById(R.id.layout);
        }
    }
    public void removeAt(int position) {
        adapterlist.remove(position);
        notifyDataSetChanged();
    }
}

Answer 1

Filter the data in list before passing to Adapter

 ArrayList<Dbbean> list = yourlist; 

Create a filtered list

  ArrayList<Dbbean> filteredList = new ArrayList<>();
  for(Dbbean dbean : list){
    if(dbean.blename.startsWith("Dev")
     filteredList.add(dbean);
  }

Pass filtered list to Adapter

EvelistAdapter adapter = new EvelistAdaptr(this,filteredList);
yourRecyclerView.setAdapter(adapter);
