Data Binding in a Kotlin World
summary
Data binding generates Java glue from XML so Kotlin code drops findViewById and manual setters, using KAPT and the dataBinding flag; a demo dog app shows binding a Dog model, generated binding.setDog, and two-way binding on EditText that updates the model automatically. The talk builds Kotlin delegates (a lazy delegate for binding, and a bindable property delegate) and demonstrates custom BindingAdapters, recycler‑view shared viewmodels, TransitionManager animations, and practical notes on Dagger, RxJava and LiveData integration.
