it might be due to an error in one of the attributes in your layout xml

@sarah.neo You're right, I found it out
@lovis Thanks. It was due to version difference between databinding compiler and gradle
@sarah.neo Thank you very much
At first, I tried @lovis suggestion, and it worked.
Then after some changes to the xml layout, it didn't work anymore, and I didn't think it was due to xml layout error.
I tried comment out all stuff in the xml layout and it worked now.
