@rkeazor Thanks for your reply and suggestions! I thought about implementing what you propose first but with databinding: - the list_fragment.xml RecyclerView layout with

android:visibility="@{adapter.itemCount > 0}

- a list_empty.xml layout with

android:visibility="@{adapter.itemCount == 0}

The issue is that I have trouble linking the

adapter

variable to the xmls 😕

I think you should keep all logic out of xml

what I’ve done in the past when experimenting with

RecyclerView

and data binding, is keep a bindable collection in a view-model

then create an abstract adapter, what I aimed for was

something that can bind a

List

,

ObservableList

,

ObservableArrayMap

, and

SortedList

. The solution was very complex under the hood, I never managed to get it out there, fully tested with example code, but plan to

current repo, not updated it in ages, but working on unit tests just now: https://github.com/Aidanvii7/Toolbox/

also changed a lot and not pushed… so not final

it’s mostly Java, with a think kotlin layer over certain parts

anyway, that aside, in xml, I aimed for syntax like this:

app:bind_collection="@{viewModel.observableList}"
