Answer 1

You can add click listener this way to your grid view items in Kotlin

grdlyt_merchant_color_code.onItemClickListener = AdapterView.OnItemClickListener { parent, view, position, id ->
            loyaltyColor = parent.getItemAtPosition(position) as LoyaltyColor?
            colorCode= LoyaltyUtils.getLoyaltyColorById(loyaltyColor!!.colorId).colorCode
            val color = ContextCompat.getColor(requireContext(), colorCode!!)
            shape.setColor(color)
            loyalty_card_img.background = shape
            uncheckAllColors()
            loyalty_card_img.visibility = View.GONE
            loyaltyColor!!.isColorSelected = true

            mAdapter.notifyDataSetChanged()
        }
