Zoom in on AppBarLayout while scrolling down

Question

I’ve been trying for quite a while to achieve the zoom effect on AppBarLayout when you go down anywhere on the page (overcroll).

An example of the desired effect: https://android-arsenal.com/details/1/4443

My layout has the following layout (irrelevant views removed):

--CoordinatorLayout
    -- AppBarLayout
        -- CollapsingToolbarLayout
             --FrameLayout
                 --ImageView
    -- NestedScrollView
        -- ...

I managed to get closer to the desired behavior when flashing the NestedScrollView (using this ), but I had no luck calling the add-on behavior on the AppBarLayout.

Any suggestions?
