    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintBottom_toBottomOf="parent"/>

Scroll listener

Add a scroll listener to get the value on scroll:

ruller.scrollListener = object: ScrollRulerListener {
    override fun onRulerScrolled(value: Float) {
        //...
    }
}

Set min, max, initial value

Set the minimum value, maximum value, and initial value through code:

ruller.reload(min = 50f, max = 250f, initValue = 180f)

Scroll to a value

ruller.scrollToValue(value = 123f)
