问题 Looking for something really simple. I looked around in the source code for RecyclerView but couldn't find anything for this. Before I start implementing my own version, I wanted to know if someone knows of anyway to receive a callback on the animation for notifyiteminserted , notifyitemremoved , notifyitemmoved ?
