The problem that you have two direct views inside the NestedScrollView
, and There should be a single root layout within the `NestedScrollView, and then you can nest any other layout within this root.
To fix your problem, you have to wrap the LinearLayout
& the RecyclerView
within a root which is arbitrary picked as LinearLayout
:
