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

I was calling my onClick wrong, which caused this error. So I changed

android:onClick="@{listener.onDogClicked()}"

to

android:onClick="@{listener::onDogClicked}"
