Hard to tell from the small snippets you posted. It would also be better to post the code inside code tags, rather than screenshots. Makes it hard to copy and reference things.

 

The compiler can't seem to find the "databinding" package in the first screenshot, so I assume one of the following is true:

• You haven't added dataBinding in the correct place in the build.gradle file
• You haven't run a Gradle sync yet
• The code hasn't been generated yet
• The layout file isn't called activity_main.xml
• You have an error in your layout file

 

Remove the import, sync Gradle then rebuild your project and try to import it again.

 

~edit: I just noticed that your top level element is "Layout", which makes no sense. If you mouse over the yellow highlight Android Studio should tell you that this element isn't allowed there. If you fix your layout it should probably fix your view binding issues.
