Custom Tutorial(A Instance)(Hands on)

Step1. Design your curve.

your can design your curve anyway.

sources link.

Step2. Parse to sources.

run App:

Step3. Parse the Coordinate System.

From right-up coordinate System to right-down coordinate System.

y = 1 - points.asSequence().mapIndexed { index, vector2 -> b(t, index + 1, vector2.y) }.sum()

Step4. Set init offset.

The first item should be center of screen, it means t=0.5 not t=0.

val t = i + .5f

Step5. Set spacing.

override fun getItemSpacing(size1: CurveLayoutManger.Vector2, size2: CurveLayoutManger.Vector2): Float {
    return .1f
}

Step6. Set start/end offset.

If you don't want position first item at center of screen. but right out of screen, and do the same to last item. your should implements getStartOffset,getEndOffset.

override fun getStartOffset(size: CurveLayoutManger.Vector2): Float {
    return .5f
}

override fun getEndOffset(size: CurveLayoutManger.Vector2): Float {
    return .5f
}

More else?
