RxBinding
RxJava binding APIs for Android's UI widgets
...To describe the interaction pattern with standard Android code, you would usually need to use a combination of both listeners, Handlers and AsyncTask. With RxJava and RxBinding, this logic can be greatly simplified and you can describe the interaction patterns between multiple UI components. You can use the RxJava to convert Android view events to Observables. Essentially the library wraps the listener and implements the Observable interface. RxBinding can be indicated as an extension for RxJava, which helps you to use it on Android development simply and easily.
