@Override
    public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
        // fab should scroll out down in sync with the appBarLayout scrolling out up.
        // let's see how far along the way the appBarLayout is
        // (if displacementFraction == 0.0f then no displacement, appBar is fully expanded;
        //  if displacementFraction == 1.0f then full displacement, appBar is totally collapsed)
        float displacementFraction = -verticalOffset / (float) appBarLayout.getHeight();

        // need to separate translationY on the fab that comes from this behavior
        // and one that comes from other sources
        // translationY from this behavior is stored in a tag on the fab
        float translationYFromThis = coalesce((Float) fab.getTag(R.id.fab_translationY_from_AppBarBoundFabBehavior), 0f);

        // top position, accounting for translation not coming from this behavior
//        float topUntranslatedFromThis = fab.getTop() + fab.getTranslationY() - translationYFromThis;

        // total length to displace by (from position uninfluenced by this behavior) for a full appBar collapse
        float fullDisplacement = parent.getBottom() - parent.getPaddingBottom();

        // calculate and store new value for displacement coming from this behavior
        float newTranslationYFromThis = fullDisplacement * displacementFraction;
        fab.setTag(R.id.fab_translationY_from_AppBarBoundFabBehavior, newTranslationYFromThis);

        // update translation value by difference found in this step
        fab.setTranslationY(newTranslationYFromThis - translationYFromThis + fab.getTranslationY());
    }
