in your ViewHolder findViewById your imageView by its id not a drawable

change this line

 @SuppressLint("ResourceType")
 var kontrol:ImageView=itemView.findViewById(R.drawable.cevap)

to

var kontrol:ImageView=itemView.findViewById(R.id.yourImageViewId)

You need to add id of your imageview at place of drawable as below -

Replace this

   var kontrol:ImageView=itemView.findViewById(R.drawable.cevap)

with this

   var kontrol:ImageView=itemView.findViewById(R.id.yourimageviewid)
