Descent Into Data Binding
summary
Step-by-step demo shows how to enable the new Android data binding library, add enable dataBinding = true, wrap a layout to generate a ListItemCrimeBinding class, and replace manual view lookups with generated fields. It inspects generated code to diagnose delayed updates and fixes them with executePendingBindings. It explores binding adapters, lambda click wiring, and moving logic into an observable ViewModel for testable properties and proper rebind notifications, and notes two‑way binding and include-composition as deeper options.
