A binding class is generated for each layout file. By default, the name of the class is based on the name of the layout file, converting it to Pascal case and adding the Binding suffix to it. The above layout filename is activity_main.xml so the corresponding generated class is ActivityMainBinding. This class holds all the bindings from the layout properties (for example, the user variable) to the layout's views and knows how to assign values for the binding expressions.The recommended method to create the bindings is to do it while inflating the layout, as shown in the following example:

//============================java Code Start =========================================

//class add Binding

ActivityLasklabcheckboxBinding Binding;

===================================================================================

//Binding Create Actitivity Page Name ,initail xlm and set view 

//Method Code

Binding =
        ActivityLasklabcheckboxBinding.
                inflate(getLayoutInflater());
View view = Binding.getRoot();
setContentView(view);
