I have a PopupWindow which contains a RecyclerView filled with items. I want to dismiss the PopupWindow after selecting an item in the recycleview. I know it has to be implemented with a interface, but not quite sure on how to do it in the code. Right now the items are displaying in the popupwindow and I could get the items printed in toast. It will be helpful if anybody could look to my code and guide me.
