What is the best way to use startSwipe function of ItemTouchHelper

Question

I created a custom LayoutManager and TouchHelper.Callback to have a tinder-like card stack. I want my layout manager to allow only the first item to have a touch event. Firstly I override the isItemViewSwipeEnabled() of ItemTouchHelper.Callback to disable touch event for each child. As the last step, I need to allow the first item to have a touch event only. However, I am failed to do so. Is anybody know how to overcome it?

• StackLayoutManager to create child views.

• StackTouchHelperCallback to disallow default touch events.

• StackView a custom RecyclerView.

This is the custom view hierarchy I developed. If anybody developed some kind of views, can them help me? Thanks in advance.

You can override the getMovementFlags method and return 0 in case you dont want to allow any movement, otherwise return appropriate direction flags.

override fun getMovementFlags(recyclerView: RecyclerView, viewHolder:RecyclerView.ViewHolder): Int {
        return if(viewHolder.adapterPosition == 0) /* return appropriate direction flags */ else 0
}
