Can not remove generated DataBinding code

问题

I used DataBinding in one of my classes CardRecicleViewAdapterTech.class , but I imported a library which does not support DataBinding and I switched to butter knifefor that class. The problem is that when I run the project, Android Studio always generates a class binding related with CardRecicleViewAdapterTech.class and this causes a crash. The generated class is:

CardViewTechBinding.java

I have deleted that java file in Android Studio databinding folder, but its generated again and again even when I do not use databinding anymore in my xml or my class.

This is my layout where I do not using dataBinding

card_view_tech.xml

so that generate CardViewTechBinding.java even when I am not using dataBinding

<?xml version="1.0" encoding="utf-8"?>

<android.support.v7.widget.CardView

I tried to restart my Pc and Invalidate cache and restart Android Studio but without success. Please help.

回答1:

In this order:

1.- Remove your file generated (build folder)
2.- Clean your project
3.- Invalidate cache and restart Android Studio
4.- Restart computer

回答2:

I had the same issue, and it was caused by having <layout> root tags in the XML. I did not realise that these tags were databinding related and the compiler also does not help you in this regard.

回答3:

In app build.gradle disable it first by using:

dataBinding { enabled = false; }

and sync the project and then enable and sync the project
