  <pre><code>@Override
      public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
       //   holder.txt_draft_vin.setText(movieList.get(position).getTitle());
  
          final boolean isExpanded = position == mExpandedPosition;
          holder.expandableLayout.setVisibility(isExpanded ? View.VISIBLE:View.GONE);
          holder.expandableLayout.setActivated(isExpanded);
          holder.img_caret.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View v) {
                 
                      mExpandedPosition = isExpanded ? -1 : position;
                      notifyItemChanged(position);
                      notifyItemChanged(mExpandedPosition);
                      notifyDataSetChanged();
