android: data binding error: cannot find symbol class

Question

I am getting started for using DataBinding feature. I am facing problem with it.

Error:(21, 9) error: cannot find symbol class ContactL

Answer 1

You need to add the tags into your Activity's Xml Layout.

and then, add an android:id into your tag

After that, you'll have a ActivityContactListBinding object and you can access and bind variables on your included layouts.
