set button in recyclerview

[wlchfl5358]

i tried setOnClickListener in onBindViewHolder and ItemViewHolder...
but it happened nothing when i clicked.
should i use different way to set button in a row in recyclerView?
may i see some example?
even i tried in activty not adapter, it shows same.
and how can i change drag clickevent recyclerview to imageview or button?
thank you.
