Databinding don't work

[cristiandaulisio]

I'm trying to bind app:srb_rating="@{viewModel.rating}" but i receive this error:

Cannot find a setter for <com.iarcuschin.simpleratingbar.SimpleRatingBar app:srb_rating> that accepts parameter type 'float'

If a binding adapter provides the setter, check that the adapter is annotated correctly and that the parameter type matches.
