It is related to this topic : Intelligent scroll in a list
I’m searching for a way to do as in the linked video 
@Zia_Choudhary , I just tested your app and the behaviour is not the same as the one from the video
Actually you just set the header value to the clicked cardview or check scroll position (with a pixel number, I wonder if it will works on every device 
)
Maybe I can investigate with the Colin Tree’s extension (ScrollArragementHandler)
By the way, thanks for your help
