constraint layout coordinator layout

I have a ConstraintLayout as my main layout. Inside it, I have a CoordinatorLayout. I want to know if ever will I be able to constrain the views I put inside the CoordinatorLayout.

Thanks in advance

Solution

  • No. You can only constrain views that are direct children of the ConstraintLayout.

    It isn't specifically CoordinatorLayout that makes you unable to do this. Any view you put inside a ConstraintLayout (other than another ConstraintLayout) won't be able to apply constraints.

    Any app:layout_constraint... attribute you apply to any view that doesn't have a ConstraintLayout as its immediate parent will simply be ignored.
