Custom interface in recycler view blocking UI change

[iseva fuji]

hello,
I have a nested recycler view with ItemView click listener in child recyclervi

ew, where on click of item-view background color of the card will get change,  also on click of items I'm putting objects in separate ArrayList and pass it to an interface and accessing it from MainActivity (if array pass-through interface  size >0  button enables on main activity for API call) here is my code

Click Listener

 holder.itemView.setOnClickListener(v -> {
            if (skillModel.getStatus().equals("Draft")) {
                skillModel.setSelected(!skillModel.isSelected());
                holder.cardView.setBackgroundColor(skillModel.isSelected() ? Color.parseColor("#E4E4E4") : Color.WHITE);

                ArrayList<SkillModel> skillArray = new ArrayList<>();

                for (SkillModel skillModel1 : skillModelArrayList) {
                    if (skillModel1.isSelected()) {
                        skillArray.add(skillModel1);
                    }
                }

                listener.itemClick(skillArray);

            }
        });

INTERFACE

   public interface ItemListener {
        void itemClick(ArrayList<SkillModel> skillModel);
    }

if I comment out   listener.itemClick(skillArray);   color of cards clicked get change, but another functionality depends on it get stopped.
any help/suggestion can be very helpful.
