Answer 2

If DataBinding class name is correct and you used to clean and rebuild project but it still show error.
Then you try to restart AndroidStudio

Answer 3

I've cleaned the project , Rebuild was done...but of no use. Then invalidated caches and restarted the project that too didn't helped me.

Then I changed my xml file name - that worked fantastically fine.

So, I would like to share you one thing, please change your xml file name.

For eg: If your xml file is: activity_main.xml and you can't get ActivityMainBinding in its Java class..........then change xml name to main_activity.xml and then use MainActivityBinding in its java class as 'private MainActivityBinding binding;'

This will do most probably.

Answer 4

try to review your xml, if has a value which was setted wrong. This is probably something about wrong databinding settings

Answer 5

Check that you activity/fragment's xml and class have consistent names; for example, if you have TimePickerFragment than xml file name should be time_picker_fragment.

It occurred to me that I had the layout named fragment_time_picker; after I changed it the binding was generated.

Answer 6

In such cases, if neither rebuild nor invalidate caches work, then there must be an error in one of your xml files where you may have used @{xyz.abc} and there must be a problem with either xyz or abc in the xml.
