Recyclerview - Changing Selected Item Icon Needs Two Clicks To Work

I am working on a mailing app, in which user can send the same mail to multiple contacts. When I open the contacts list I want to be able to click on the user and his profile pictu

Solution 1:

There's no need to call notifyItemChanged on the toggleSelection method. You are alredy changing the item manually with animations.

Calling notifyItemChanged is what causes the flickering, because it interferes with the animations.
