Viewpager PageTransformer animation both background to foreground and foreground to background?

Question

I implemented viewpager with transformer animation but here is different animation apply this Background To Foreground and Foreground To Background.

viewPagerAddToCart.setPageTransformer(true, new BackgroundToForegroundTransformer());

And also to different Foreground To Background

viewPagerAddToCart.setPageTransformer(true, new ForegroundToBackgroundTransformer());

But i need to both together.

I used this library https://github.com/geftimov/android-viewpager-transformers but here it is separate animation not in combine animation.

So, Android people plz help how to use both animation as same time left to right and right to left.

Thank You!
