ViewHolder views must not be attached when created

In my case, I fixed it changing this line

val view = parent.inflate(R.layout.your_item)

to

val view = parent.inflate(R.layout.your_item, false)

Actually, your ViewHolder expects a View inflated from R.layout.text_row_item rather than a descendant of the latter. So, if you pass the inflated view the problem will be resolved.

So, you should correct your code to this:

public class MyRvAdapter extends RecyclerView.Adapter<MyRvAdapter.ViewHolder> {

    private String[] mDataset;

    public static class ViewHolder extends RecyclerView.ViewHolder {
        // each data item is just a string in this case
        public TextView mTextView;
        public ViewHolder(View v) {
            super(v);
            mTextView = v.findViewById(r.id.display_name);
        }
    }

    public MyRvAdapter(String[] myDataset) {
        mDataset = myDataset;
    }

    @NonNull
    @Override
    public MyRvAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.text_row_item, parent, false);
        ViewHolder vh = new ViewHolder(v);
        return vh;
    }

    @Override
    public void onBindViewHolder(@NonNull MyRvAdapter.ViewHolder holder, int position) {
        holder.mTextView.setText(mDataset[position]);
    }

    @Override
    public int getItemCount() {
        return mDataset.length;
    }
}
