Material Button Toggle Group single selection

Question

How can I force a MaterialButtonToggleGroup to act like a RadioGroup as in having at least one selected item always? Setting setSingleSelection(true)

Answer 1

If you really want to do this, you can go about it this way in Kotlin.

toggle_group.forEach { button ->
      button.setOnClickListener { (button as MaterialButton).isChecked = true }
}

This will prevent second click unchecking.
