Android Studio – How can I create 'Swipe on a message to reply on WhatsApp' kind of view using custom view on list?

I have a list of items in list view, I want to display the item that user swipes left on, in a new fragment or activity as a textview. I want the entire list to animate and move a bit to left as if it has been pulled to left with the finger. I want to execute the same using custom views.

    You can either add Swipeable behavior to your RecyclerView like this :

    or use an external library to do that for you :

    I think the following post gives the most detailed equation for this behaviour. It relates the finger position to the bubble position and can be customised easily.

    xb = min( xf, f * sqrt(W) * sqrt(xf) )

xb = x-displacement of bubble from its initial position
xf = x-displacement of finger from its initial position
W  = screen width or maximum finger displacement possible
f  = maximum bubble displacement fraction or xb(max)/xf(max)
