Android Data Binding : Observable List to RecyclerView's Adapter

Question

Is their a way, by using the ObservableList class from the new Data Binding library and the MVVM pattern, to avoid using "notifyItem(s)..." methods from the Adapter class?

Or if not what could be the simpliest way to bind an ObservableList to a RecyclerView?

Thank's for any clue !

Have a look at following implementation of the RecyclerView's adapter:

https://github.com/radzio/android-data-binding-recyclerview/blob/master/recyclerview-binding/src/main/java/net/droidlabs/mvvm/recyclerview/adapter/BindingRecyclerViewAdapter.java

It automatically notifies the recycler view if the OnListChangedCallback is called.

Also have a look at the rest of the repository. It shows how to bind your ObervableList to the adapter using xml. So that you can have something like this:

app:items="@{usersViewModel.users}"
