Ok looks like you need to define a val to assign it, maybe is because it only accept inmutable values on ID's.

import org.jetbrains.anko.relativeLayout
import org.jetbrains.anko.textView

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        var counter = 0
        val ID_OK = 11
        relativeLayout(){
            val counterTextView = textView {
                id = ID_OK
                text = "0"
                textSize = 24f
            }

            button {
                setOnClickListener {
                    counter++
                    counterTextView.text = counter.toString()
                }
            }.lparams {
                below(counterTextView)
            }

        }
    }
}

import org.jetbrains.anko.relativeLayout
import org.jetbrains.anko.textView

class MainActivity : AppCompatActivity() {

    @SuppressLint("ResourceType")
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        var counter = 0
        relativeLayout(){
            val counterTextView = textView {
                id = 11
                text = "0"
                textSize = 24f
            }

            button {
                setOnClickListener {
                    counter++
                    counterTextView.text = counter.toString()
                }
            }.lparams {
                below(counterTextView)
            }

        }
    }
}

adding @SuppressLint("ResourceType") made the error go away.

It works but thats not the correct way to solve things.
