Floating Action Button hide when scrolling with Webview

Question

Is it possible to hide fab button when scrolling down with Webview and appear when scrolling up? Like with the Recycler View effect/animation with fab.

@TargetApi is required as setOnScrollChangeListener() doesnt work for under 23 apis.

@TargetApi(23)
public void hideFabOnScroll(){
    webView.setOnScrollChangeListener(new View.OnScrollChangeListener() {
        @Override
        public void onScrollChange(View v, int scrollX, int scrollY, oldScrollX, int oldScrollY) {
            if (scrollY > oldScrollY)
                fab.hide();
            else if (scrollY < oldScrollY)
                fab.show();

        }
    });
}
