RecyclerView came over ListView and its major property that is It Reuses cells while scrolling up and down. Due to this it do not flick while scrolling even if you have lots of data in your list. You are getting problem due to Reuse of cells in RecyclerView.

You can display checkbox checked or unchecked on basis of cell position and corresponding data. In my sample i used setOnClickListener instead of setOnCheckedChangeListenerto to show checkbox checked or unchecked.
