I can not find this view. My version of android studio is 3.2.1. Also the constraint controls in figure 9.8 are much different on my version of android studio.
Sorry, I posted this in the wrong place. Can a moderator please move it here? https://forums.bignerdranch.com/c/android-programming-3rd-edition/9-creating-user-interfaces-with-layouts-and-widge
Silly mistake. Just click on the view in the component tree.
And you should see your properties/attributes view for that view.
