Click overlay [ImageButton inside a CardView]

Hello, I have a CardView with clickListener When I click the button it calls the RecyclerClickListener But I'd like it to call the Button click event when it was clicked by ignoring the RecyclerClickListener

CardView click event:

 recyclerSpells.addOnItemTouchListener(
            new RecyclerClickListener(
                    getContext(),
                    recyclerSpells,
                    new RecyclerClickListener.OnItemClickListener() {
                        @Override
                        public void onItemClick(View view, int position) {
                            List<Spell> updatedSpellList = adapterSpells.getSpellList();

                            Spell clickedSpell = updatedSpellList.get(position);

                            isNew = false;
                            Intent intent = new Intent(getContext(), AddActivity.class);
                            intent.putExtra(IntentExtra.USER.toString(), user);
                            intent.putExtra(IntentExtra.CHARACTER.toString(), character);
                            intent.putExtra(IntentExtra.OBJECT.toString(), clickedSpell);
                            intent.putExtra(IntentExtra.ISNEW.toString(), isNew);
                            startActivity(intent);
                        }

                        @Override
                        public void onLongItemClick(View view, int position) {

                        }

                        @Override
                        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

                        }
                    }
            ));

RecyclerClickListener class:

public class RecyclerClickListener implements RecyclerView.OnItemTouchListener {

private OnItemClickListener mListener;
GestureDetector mGestureDetector;

@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
    View childView = rv.findChildViewUnder(e.getX(), e.getY());
    if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
        mListener.onItemClick(childView, rv.getChildAdapterPosition(childView));
        return true;
    }
    return false;
}

@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {

}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

}

public interface OnItemClickListener extends AdapterView.OnItemClickListener {
    public void onItemClick(View view, int position);

    public void onLongItemClick(View view, int position);
}

public RecyclerClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) {
    mListener = listener;
    mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
        @Override
        public boolean onSingleTapUp(MotionEvent e) {
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
            if (child != null && mListener != null) {
                mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child));
            }
        }
    });

}

}

Button click event:

    Spell spell = spellList.get(position);

    holder.name.setText(spell.getName());

    if(spell.getCastingTime() == null)

    else
        MyTextFormat.adapterBoldText(spell.getCastingTime(), holder.castingTime);

    else

        MyTextFormat.adapterBoldText(spell.getCost(), holder.cost);



    holder.description.setMaxLines(isSpellExpanded ? 20 : 1);

    if(holder.description.getMaxLines() == 20){
        holder.btn_expand.setImageResource(R.drawable.ic_arrow_up_black_24dp);
    }
    else {
        holder.btn_expand.setImageResource(R.drawable.ic_arrow_down_black);
    }

    holder.btn_expand.setOnClickListener( view -> {
        isSpellExpanded = spell.isExpanded();
        spell.setExpanded(!isSpellExpanded);
        notifyItemChanged(position);
    });
}

How could I solve this?
