How to show 20 fake items when loading the recyclerview?

Question

I'm trying to show some list of items in a recyclerview, following the next article GIT REPO. I need to load 20 fake items before the recyclerview loads the next real items, as a loading. But I don´t know how to insert this cells and later.

Someone could give me a hand?

do same way as after the items load, but create 20 items manually, and use them — Vladyslav Matviienko, Feb 07 '18 at 11:24
Before you pass your ArrayList or List to your adapter make sure you add some dummy value. — Enzokie, Feb 07 '18 at 11:25

"Fake" items are just "items" to RecyclerView – there's no difference between them. Hence to show them you'd have to use the same thing you use to show "ordinary" items in RecyclerViews: a RecyclerView.Adapter.

The component responsible for placeholder views like the one you've shown above is actually the activity/fragment containing the RecyclerView. Here's a rough illustration of how it might work:

Make sure your adapter could handle (at least) 2 view types: one for your real view, one for the placeholder.
Whenever you're loading your data, add null objects to your adapter's List.
Configure your adapter to inflate a placeholder view whenever it's being asked to render a null object.
When your data is loaded, replace those null objects with an actual object coming from your data store.
