Description:

  1. I recently updated whatsapp and noticed the animation for menu item clicked on toolbar. How to achieve this effect?
  2. Are there any opensource projects to achieve this?
  3. I have not posted any code because. I have no clue how they are doing it.

Seems like they "ported" lollipop animation in pre-L devices. The simplest way to do this is using libraries like Igvalle's Material-Animation (see #4). Its minSdk is 16, but I hope you can decrease it for 14 or below.

Some other libraries: TransitionsBackport, PreLollipopTransition, transitions-everywhere.

Please let me know if you create this animation!

    I have to say my github project is not really a library but an example of how to do this kind of animations :) – lgvalle Sep 03 '15 at 08:24
