Which kind of Button are you importing?

[Ben Edwards]

@Juliane Lehmann

import android.widget.Button

Thanks, yes having different imports for Button was what through me but got it working

val button1 = Button(this)
button1.setLayoutParams(ConstraintLayout.LayoutParams(600, 180))
button1.text = "Button added"
layout.addView(button1)
