okay I managed to find out pretty cheap solution but it seems to work. just put your spinner creation logic in xml, say like that :

<Spinner 
     xmlns:android="http://schemas.android.com/apk/res/android"
     style="@style/Widget.AppCompat.Spinner.Underlined"

    layoutInflater.inflate(R.layout.item, frameLayout)

    val arrayAdapter = ArrayAdapter(this, R.layout.support_simple_spinner_dropdown_item, spinnerItems)
    arrayAdapter.setDropDownViewResource(R.layout.support_simple_spinner_dropdown_item)

    mySpinner.adapter = arrayAdapter
