I posted how to setup Kotlin and DataBinding in Android Stuido in the last blog (http://marksunghunpark.blogspot.com.au/2017/04/kotlin-binding-library-setup-in-android.html). In this post, I am going to how to use DataBiding in the MainActivity when you create a navigation drawer project from Android Studio templates. Layouts You will have four layouts in app/src/res/layout folder: app/src/main/res/layout/activity_main.xml app/src/main/res/layout/app_bar_main.xml app/src/main/res/layout/content_main.xml app/src/main/res/layout/nav_header_main.xml And activity_main.xml contains all other layout using include layout. You need to have tag in activity_main.xml , app_bar_main.xml and content_main.xml . If you don't have the tag, Binding library cannot recognise the sub layouts properly. Binding library doesn't support toolbar and navigation drawer yet, so you can use using BindingAdapter if you want to use binding library.(But I'm gong to skip this part for simplici
