Answer 1

Add this is your build.gradle(Module:app) file

android {

dataBinding {
    enabled true
}

}

Answer 2

I had the same problem. I tried a couple of things, Clean and Rebuild project.

But, It worked after I choose File -> Invalidate Caches / Restart

Answer 3

When I first meet this error, I create a layout named a.xml, and then I Create a Activity like this

public class ABinding extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ABinding binding = DataBindingUtil.setContentView(this, R.layout.a);
    }

}

and this error occurs. Finally I found out Class ABinding was automatically generated in /build, so activity with name ABinding will overwrite the auto generated class

so I rename the Activity and the error disappear

Answer 4

add this in build.gradle

   android{
 ....
    dataBinding 
      { 
     enabled = true
       }
...
    }

Answer 5

If all the solutions mentioned above didn't work out go to your .gradle folder > caches and delete all folders with name starting with transforms i.e. transforms-1 & transforms-2. This works for me

Answer 6

You should use ActivityMainBinding in place of your Activity class name.

ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_checklists);
