When your button is clicked change white color for rest of the buttons like this 

btnOpt1.setOnClickListener {
    btnOpt1.setCardBackgroundColor(Color.parseColor("#fcfca9"));
    btnOpt2.setCardBackgroundColor(Color.parseColor("#ffffff"));
    btnOpt3.setCardBackgroundColor(Color.parseColor("#ffffff"));
    btnOpt4.setCardBackgroundColor(Color.parseColor("#ffffff"));
}

Create the method and pass your view for selected and unselcted

       btnOpt1.setOnClickListener {
          clickCardView(btnOpt1)

        }

Create the method and call from your all click listeners 

    private void clickCardView(View btnView){
        btnOpt1.setCardBackgroundColor(Color.parseColor("#ffffff"));
        btnOpt2.setCardBackgroundColor(Color.parseColor("#ffffff"));
        btnOpt3.setCardBackgroundColor(Color.parseColor("#ffffff"));
        btnOpt4.setCardBackgroundColor(Color.parseColor("#ffffff"));

//// main logic is here

    btnView.setCardBackgroundColor(Color.parseColor("#fcfca9"));
    }
