setViewModel method is not available

mBinding.setViewModel(new SoundViewModel(mBeatBox));

would you help me please

Make sure you’ve updated your XML to list add a variable. The variable is called ‘viewmodel’ so a setViewModel method is generated for you.

I have the same issue. I have done everything as specified and even rebuilt the project. But the problem persists. Any ideas?

Solved. Just had to close and reopen Android Studio
