it generates automatically as per your activity layout name when you include your activity layout in <layout> tag.
like this
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="sample.android.databinding.MainActivity">
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:textSize="20sp" />
</RelativeLayout>
</layout>So when you use elements of this layout with defined id’s so there is no need for the statement ‘findViewById’, you can directly use them from ActivityMainBinding class. So it is a auto generated class.
