data binding - Can't resolve Android databinding class

Question

While using data binding , I am not able to get class MainActivityBinding as per Data Binding Guide

My layout name is activity_main.xml. I am also see Android - DataBinding - How and when the Binding classes will be generated? but it can't help me.

Answer 1

DataBinding class will be generated based on your xml file name. It is clearly mentioned in doc you are following.

By default, a Binding class will be generated based on the name of the layout file, converting it to Pascal case and suffixing “Binding” to it. The above layout file was main_activity.xml so the generate class was MainActivityBinding

If your xml name is activity_main.xml than DataBinding class name will be ActivityMainBinding.

If your xml name is main_activity.xml than DataBinding class name will be MainActivityBinding.

Dont forget to clean and build project once
