Android'de google chrome animasyonu etkisi

Question

2 veya daha fazla sekme açarken google chrome'da kullanıldığı gibi animasyon oluşturmaya çalışıyorum. İşte aşağıdaki resim.

Bu efekti Google Chrome'da olduğu gibi nasıl yapabilirim? Onlar SlidingDrawer gibi animasyon (ama o kadar bildiğim kadarıyla bir SlidingDrawer değildir.)

Google'ın krom etkisi ancak gelecekte belki yararlı birisi olarak tam değildir.
