According to the doc
With the release 23.2.0 there is an exciting new feature to the LayoutManager API: auto-measurement!
This allows aRecyclerView
to size itself based on the size of its contents. This means that previously unavailable scenarios, such as using WRAP_CONTENT for a dimension of the RecyclerView, are now possible.
You’ll find all built in LayoutManagers now support auto-measurement.
Due to this change, make sure to double check the layout parameters of your item views: previously ignored layout parameters (such as MATCH_PARENT in the scroll direction) will now be fully respected.
In your item layout you have to change:
android:layout_height="match_parent"
with
android:layout_height="wrap_content"
