Why does my recyclerview show the same image?

Good guys, I have a recyclerView with different images, I want to press any image and it is reflected in another activity, my problem is that when pressing on any image the same image is always displayed.

class LugaresFragment : Fragment(), RecyclerAdapter.OnClickListener {

  override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_lugares, container, false)
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        val list = ArrayList<Sitios>()

        list.add(Sitios(R.drawable.filesharing, "Holaa","hola2"))
        list.add(Sitios(R.drawable.travelcase, "Holaa","hola2"))
        //Metodo para mostrar los elementos de recyclerView
        recyclerView.layoutManager = LinearLayoutManager(context)
        recyclerView.adapter = RecyclerAdapter(context,list,this)
    override fun onImageClik(img: Int) {
      val intent = Intent(context,ImageDetail::class.java)
    override fun onItemClik(title: String) {
        TODO("Not yet implemented")

class ImageDetail : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {

        intent.getStringExtra("CLAVE")?.toInt()?.let { imageCardView.setImageResource(it) }
