This is my note for Udemy lesson: Advanced Android Bootcamp 2024. 1. Set up Data Binding Please see my previous note. 2. Edit the xml File <layout ...> <data> <variable name="student" type="com.xxx.xxx.Student" /> </data> <androidx.constraintlayout.widget.ConstraintLayout ...> ... </androidx.constraintlayout.widget.constraintlayout></layout>

1. In app/build.gradle, add the following code: android { ... dataBinding { enabled = true } } Also it can be android { ... buildFeatures { dataBinding = true } } 2. Add an extra layout in layout xml file. Before: <androidx.constraintlayout.widget.ConstraintLayout xmlns:... android:...> ... </androidx.constraintlayout.widget.constraintlayout>
