Example

[domgeorg]

can you give us an example-sample xml file of a complex implementation

what if the only scrollable view of the parent coordinator is inside the child coordinator
RelativeLayout
--CoordinatorLayout
----AppbarLayout
-----LinearLayout(scroll behavior)
-------Framelayout
-------Framelayout
--Framelayout

and add a fragment in the firt Framelayout with
NestedScrollCoordinatorLayout
--AppbarLayout
----Recyclerview(scroll behavior)

You can only use NSCL as a direct child of the outer CL, as far as I remember.

I have the same issue, any workaround when the NSCL is not a direct child of a CL?

[natario1]

Nope!

If the nested coordinator layout has to be a direct child of the parent coordinator layout then what is the purpose of it? For example:

(Coordinator layout with bottom navigation) ->
(FrameLayout for fragments) ->
(Coordinator layout for each fragment)

If I place nested coordinator layout as a direct child it would look like this

(Coordinator layout with bottom navigation) ->
(Coordinator layout as a fragment holder) ->
(Coordinator layout for each fragment)

Would the second setup work?

In your example, the first one can be a standard Coordinator, the other two should be NSCLs and it will work. If I remember correctly.
