There is no "ActivityPostListDataBinding" class

unresolved reference error for "ActivityPostListBinding"

You just need to follow the article steps and build the app at the point that he says to add the reference to this class. The class for the databinding will be generated.

Ran into same problem, because I missed this session in the app.gradle,

    dataBinding {
        enabled = true
    }

It also makes the annotation @BindingAdapter not found, fyi.

For those how don't follow exact guide like me, and want to use different file names.
Here is a hint. at that point you will need Make project and then, type between imports somthing like:

import {your root package}.databinding. (And press Ctrl+Space)

You will see generated class name there.
for my EventsListFragment I had to put
import com.hast.norvialle.databinding.FragmentListBinding
So for me, it was quite unclear, what was the exact name of the generated class.
