How to slide only half Fragment while using vertical ViewPager

Question

I was looking for vertical viewpager then I found this answer
it's working fine, but now I need to slide only half of the fragment.

I did this before, using horizontal viewpager with below solution

Override the getPageWidth method of PagerAdapter and make it return 0.5f;

but because I'm using vertical viewpager instead of horizontal viewpager, and FragmentPagerAdapter does not have any override method to return height

Is there any possible solution to do it?

just replace VerticalPageTransformer class with this source

private class VerticalPageTransformer implements ViewPager.PageTransformer {

    @Override
    public void transformPage(View view, float position) {

        if (position < -1) {
            view.setAlpha(0);

        } else if (position <= 1) {
            view.setAlpha(1);
            view.setTranslationX(view.getWidth() * -position);
            float yPosition = position * (float)(view.getHeight() / 2.5);
            view.setTranslationY(yPosition);

        } else {
            view.setAlpha(0);
        }
    }
}

it works perfectly ;)
