Disable SwipeRefreshLayout when horizintal scroll handled in two-way Recyclerview

Question

I have a RecyclerView with custom LayoutManager, that has two-way scrolling logic. So, I have overrided it's methods:

override fun canScrollVertically(): Boolean = true
override fun canScrollHorizontally(): Boolean = true

Then i put RecyclerView in custom SwipeRefreshLayout, to prevent "swipe to refresh" action when user scrolls my list horizontally :

class CustomSwipeToRefresh
@JvmOverloads
constructor(
        context: Context,
        attrs: AttributeSet? = null
) : SwipeRefreshLayout(context, attrs) {

    private val touchSlop: Int = ViewConfiguration.get(context).scaledTouchSlop
    private var startX = 0f
    private var forbidSwipe = false

    override fun onInterceptTouchEvent(event: MotionEvent): Boolean {
        when (event.action) {
            ACTION_DOWN -> startX = event.x
            ACTION_MOVE -> {
                if (abs(event.x - startX) > touchSlop || forbidSwipe) {
                    forbidSwipe = true
                    return false
                }
            }
            ACTION_CANCEL, ACTION_UP -> {
                forbidSwipe = false
            }
        }
        return super.onInterceptTouchEvent(event)
    }

}

But this solution doesn't work. Tryed this solution (disabling manualy), but it doesn't work too:

override fun onInterceptTouchEvent(event: MotionEvent): Boolean {
        when (event.action) {
            ACTION_DOWN -> startX = event.x
            ACTION_MOVE -> {
                if (abs(event.x - startX) > touchSlop || forbidSwipe) {
                    forbidSwipe = true
                    isEnabled = false
                    return false
                }
            }
            ACTION_CANCEL, ACTION_UP -> {
                isEnabled = true
                forbidSwipe = false
            }
        }
        return super.onInterceptTouchEvent(event)
    }

Anyway, if I write

refreshLayout.isEnabled = false

in my onViewCreated in Fragment, it became disabled.

Also tryed to disable SwipeRefreshLayout in RecyclerView.OnScrollListener, but it didn't help. What is wrong in my code, or SwipeRefreshLayout?

Ok. After several days of googling I found that all magic of showing and moving spinner located in NestedScrollingParent methods. So, I overrided onNestedScroll method and if forbidSwipe == true I just ignore super method:

class CustomSwipeToRefresh
@JvmOverloads
constructor(
        context: Context,
        attrs: AttributeSet? = null
) : SwipeRefreshLayout(context, attrs) {

    private val touchSlop: Int = ViewConfiguration.get(context).scaledTouchSlop
    private var startX = 0f
    private var startY = 0f
    private var forbidSwipe = false
    private var isStartScrolledByY = false

    override fun onInterceptTouchEvent(event: MotionEvent): Boolean {
        when (event.action) {
            ACTION_DOWN -> {
                startX = event.x
                startY = event.y
            }
            ACTION_MOVE -> {
                val isScrolledByX = abs(event.x - startX) > touchSlop
                val isScrolledByY = abs(event.y - startY) > touchSlop
                if (!forbidSwipe && isScrolledByY) {
                    isStartScrolledByY = true
                }
                if ((isScrolledByX || forbidSwipe) && !isStartScrolledByY) {
                    forbidSwipe = true
                    return false
                }
            }
            ACTION_CANCEL, ACTION_UP -> {
                forbidSwipe = false
                isStartScrolledByY = false
            }
        }
        return super.onInterceptTouchEvent(event)
    }

    override fun onNestedScroll(target: View, dxConsumed: Int, dyConsumed: Int, dxUnconsumed: Int, dyUnconsumed: Int) {
        if (forbidSwipe) return
        super.onNestedScroll(target, dxConsumed, dyConsumed, dxUnconsumed, dyUnconsumed)
    }

}
