The reason is your var input = editText.text never gets set again (even though it is a var), so in this case, It's not different from a val. You either need to reassign it or use .text directly:

  1. Set it again:

var input = editText.text var empList = arrayListOf("jacob", "raf", "boss", "john")

button.setOnClickListener {

input = editText.text // add this line

f (input == emplist) {

        textView2.setText("WORKING")

    }else{

        textView2.setText("Not working")

    }
}

  1. Or not use input at all and use text itself:

    button.setOnClickListener {

if (editText.text == emplist) {

    textView2.setText("WORKING")

}else{

    textView2.setText("Not working")

        }
}

if(empList.contains(input))

I think this will resolve your issue

You can also use the in operator: 

if (input in empList)

use this instead:

if (empList.contains(input.toString()))

This will check if the content of the EditText is equal to any of the list items. Remember to call toString() method when you want the EditText content.
