Can this be used also for RecyclerView that using GridLayoutManager?

[topex-psy]

I see an example of your project using LinearLayoutManager. I what to try this library because it looks useful, but my RecyclerView is using GridLayoutManager and the scrollbar not showing up. Is this because the layout manager or something else?

define layout manager:

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    val layoutManager = GridLayoutManager(context, 6)
    layoutManager.spanSizeLookup = object : GridLayoutManager.SpanSizeLookup() {
        override fun getSpanSize(position: Int): Int {
            return Math.min(6, if (listProdukAdapter == null) 2 else listProdukAdapter!!.getItemViewType(position))
        }
    }
    recycler_view.setHasFixedSize(true)
    recycler_view.layoutManager = layoutManager
    recycler_view.addOnScrollListener(object : MyRecyclerViewScroll() {
        override fun hide() = frg.hideBar()
        override fun show() = frg.showBar()
    })
    ...
}

setting adapter & bubble scrollbar:

listProdukBeli = listProduk.lisT_PRODUK.toMutableList()
listProdukAdapter = ListProdukAdapter(context!!, listProdukBeli!!, act, "beli")
recycler_view.adapter = listProdukAdapter

bubbleScrollBar.attachToRecyclerView(recycler_view)
bubbleScrollBar.bubbleTextProvider = BubbleTextProvider { listProdukBeli!![it].kategori }

For the bubbleTextProvider, I'm getting the category value of my product list.

my layout:

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clipToPadding="false"
            android:paddingTop="120dp"
            android:paddingBottom="70dp"
            android:scrollbars="vertical"
            android:visibility="visible"
            app:layout_behavior="@string/appbar_scrolling_view_behavior" />

        <com.trendyol.bubblescrollbarlib.BubbleScrollBar
            android:id="@+id/bubbleScrollBar"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="end"
            android:orientation="vertical"
            android:paddingTop="120dp"
            android:paddingBottom="70dp"
            app:bubbleBackground="@drawable/fast_scroll_thumb"
            app:bubbleElevation="6dp"
            app:bubbleHeight="50dp"
            app:bubbleMargin="4dp"
            app:bubbleMinWidth="50dp"
            app:bubblePadding="4dp"
            app:bubbleTextColor="@color/default_bubble_text_color"
            app:bubbleTextSize="8sp"
            app:scrollbarBackground="@color/bubbleRed"
            app:thumbBackground="@color/colorAccent" />

    </FrameLayout>
