IllegalStateException: this method cannot be called while RecyclerView evaluates layout or scroll

Question

I try to remove an item from mine RecyclerView, but always get an error message.

java.lang.IllegalStateException: Cannot call this method while RecyclerView calculates layout or scroll

I use notifyDataSetChanged(). How can i solve this?

Here is my adapter code

public class ListAdapters extends RecyclerView.Adapter<ListAdapters.MyViewHolder> {

    public ArrayList<String> tvdatalist;
    Context c;
    int pos;
    ListAdapters.MyViewHolder myViewHolder;
    private LayoutInflater layoutInflater;
    int[] arr;

    public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {


        public EditText edttxt;
        public CheckBox cb;

        public MyViewHolder(View view) {
            super(view);

            edttxt = (EditText) view.findViewById(R.id.edttxt);
            cb = (CheckBox) view.findViewById(R.id.cb);
        }

        @Override
        public void onClick(View v) {

        }


    }

    public ListAdapters(Context c, ArrayList<String> tvdatalist) {
        this.c = c;
        this.layoutInflater = LayoutInflater.from(c);
        this.tvdatalist = tvdatalist;
        arr = new int[tvdatalist.size()];
        for (int i = 0; i < 20; i++) {
            arr[i] = 0;

        }


    }

    @Override
    public ListAdapters.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new ListAdapters.MyViewHolder(this.layoutInflater.inflate(R.layout.list_ittm, parent, false));
        //return new LandingPageAdapter.MyViewHolder(itemView);
    }

    public void onBindViewHolder(final ListAdapters.MyViewHolder holder, final int position) {
        myViewHolder = holder;

        final String ShowsBean = tvdatalist.get(position);
        myViewHolder.edttxt.setText(ShowsBean);
        if (arr[pos] == 0) {
            myViewHolder.cb.setChecked(false);
            myViewHolder.edttxt.setKeyListener(null);
        } else {
            myViewHolder.cb.setChecked(true);
            myViewHolder.edttxt.setFocusable(true);
        }



        myViewHolder.cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {

                    if (arr[position]==0){
                        arr[position]=1;
                    }else{
                        arr[position]=0;

                    }
                 notifyDataSetChanged();

            }

        });

    }
    @Override
    public int getItemCount() {
        return tvdatalist.size();

    }

    public interface ItemClickListener {
        void onClick(View view, int position, boolean isLongClick);
    }
}

Answer 1

As Abbas said

This usually happens when you call a bg stream notification. So just move the notification to ui string

else you can use notifyItemChanged(position);

it will also work.

Answer 2

, , , notifyItemChanged (position) , , the- (notifyItemChanged (position ));

Answer 3

runnable .

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