how do you realize loading data asynchronously in ListFragment ? about materialistic HOT 3 CLOSED

The idea is to let RecyclerView signals you when you need to load data.

We first make a network call to v0/topstories.json to fetch all the IDs and create an array of items with no data and set it as data source for RecyclerView.Adapter.

Whenever RecyclerView needs to display an item it will trigger RecyclerView.Adapter.bindViewHolder(), at which point you make another network call to v0/item.json to fetch the item (if not yet), or bind from previously fetched item. You'll need to write logic to decide whether to fetch an item again.
