Android data binding error -- java.lang.RuntimeException: view tag isn't correct on view:null -

me , teammate working on same project and
both using android studio 2.3 , gradle 3.3
have used databinding in code , works correctly:
gradle:

... android {     ...     databinding {         enabled = true     } } ... 

my_view.xml:

<layout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto">      <relativelayout>           ....      </relativelayout> </layout> 

myclass.java:

public class myclass extends toolbar {     private myviewbinding binding;     ...     @override     protected void onfinishinflate() {         super.onfinishinflate();         initializeview();     }      private void initializeview() {         this.binding = databindingutil.inflate(layoutinflater.from(getcontext()), r.layout.my_view,this,  true);         ...     } }
