Android. Swipe to back Activity like Telegram

Question

How to swipe to previous activity using gesture and animation like in Telegram and Tinder app?

Answer 1

Telegram is using it's own created fragments.They Created a class named ActionBarLayout which is basically a FrameLayout and is added to the main Activity and the fragment is just a view class (called TelegramFragment) that is added to the ActionBarLayout (they are kept in a list and much faster than normal fragments (with a bit less features).

To do the animation , they just animate the added view.

You can see the classes work in action HERE and HERE

Answer 2

there is a good library on github where I gave my contribute: it handles this feature both with activities and fragments.
