Answer 1

your Activity or Fragment (which holds RecyclerView and adapter) isn't implementing PatientListAdapter.SelectIemClickListner , instead there is an View.OnClickListener implementation. you should add SelectIemClickListner after coma, implement needed method ( mySelectIemListner(int i) ) and then try to build an app

some sample how it should look for and Activity

class CustomActivity : AppCompatActivity(),
    View.OnClickListener, PatientListAdapter.SelectIemClickListner {

    override fun mySelectIemListner(i: Integer) {
        // on item click implementation
    }

    // rest of code
