How to make RecyclerView scroll smoothly?

Question

This is more like a generic question, but after lot of search and try I am not able to understand why this is so difficult to achieve. This is the closest answer I can find but still unable to implement.

To be specific I am using RecyclerView with GridLayoutManager. All I want is the grid layout to scroll smoothly (like default gallary app) ,nothing fancy, but the default implementation of grid layout manager scrolls the view in a 'jerky' manner. I tried to implement the method from above link but unsuccessfully.

I also tried to implement LinearSmoothScroller but I am not sure how to implement computeScrollVectorForPosition method. Google's documentation on computeScrollVectorForPosition literally has 0 words.

I found this 3 part tutorial, but it was of very little help. So, all I want to ask is: can there be some kind of template code which we can implement in LinearSmoothScroller or by extending RecyclerView.SmoothScroller and achieve smooth scrolling ? Even if the code depends on number of items and items per row in gridlayout, there has to be some method to do it easily. Am I missing something here ?
