I think some of the code snippets you’ve shared are a bit misleading because you use lambdas/mehod references in the `subscribe()` method. If your codebase is setup to use lambdas and method references, you can do exactly the same things with the `View.setOnClickListener()` or the Toolbar nav and menu click methods. In fact, you could make the argument that it’s less verbose than the RxBinding method:
toolbar.setNavigationOnClickListener(v -> onToolbarNavigationClicked());
Just as readable and you get access to the clicked view.
