Get RecyclerView orientation in custom view

Question

I'm trying to create a custom view extending RecyclerView. In my custom view, I have some things to do according to the RecyclerView orientation (horizontal or vertical).

Unfortunately, I don't find any way to know and get the RecyclerView orientation.

Is it even possible to do?

I know that RecyclerView orientation is defined in its LayoutManager. Maybe it is impossible to get this LayoutManager information?

Thank you in advance for any help you can provide.

Ok I just found the solution:

LayoutManager.getProperties(context, attrs, 0, 0).orientation

This line returns either 0 or 1 if the recyclerView is respectively HORIZONTAL or VERTICAL

Just in case, here is my customView constructor:

     public CustomRecyclerView(Context context, AttributeSet attrs) {
            super(context, attrs);

            if (LayoutManager.getProperties(context, attrs, 0, 0).orientation == 0)
                Log.d("recycler orientation", "horizontal");
            else if (LayoutManager.getProperties(context, attrs, 0, 0).orientation == 1)
                Log.d("recycler orientation", "vertical");
     }
