ArcLayoutManager.kt

class ArcLayoutManager(
    private val context: Context,
    private var horizontalOffset: Int = 0
) : RecyclerView.LayoutManager() {
    override fun generateDefaultLayoutParams(): RecyclerView.LayoutParams =
        RecyclerView.LayoutParams(MATCH_PARENT, WRAP_CONTENT)

    override fun canScrollHorizontally(): Boolean = true

    override fun scrollHorizontallyBy(
        dx: Int,
        recycler: RecyclerView.Recycler?,
        state: RecyclerView.State?
    ): Int {
        horizontalOffset += dx
        return dx
    }
}
