Relative layout inside constraint layout

#1

Hi,
i am trying to use a relative layout layout inside constraint layout but i am not able to add constraints to it using the editor whereas when I use any other layout or a widget i face no such problem, please help.

You can’t use relative layout directly inside constraint layout. Intention of ConstraintLayout is to optimize and flatten the view hierarchy of your layouts by applying some rules to each view to avoid nesting.
Basically Constraint Layout reduces nesting.
