Android : how to make View Flow with bottom shadow like iphone

Question

Going straight forward..

1.what i achieved so far (thanks to pakerfeldt- https://github.com/pakerfeldt/android-viewflow)

2.what i need actually

so almost done..but you can see bottom shadow functionality (at viewflow) in iphone screen (and it can pull down and can see entire image). so does anyone achieved something similar in android ? any other library for reference ?

Thanks in advance. answer will be appreciated. Thanks.
