Rx java solution

    public static Observable iterate(@NonNull View root) {
        return Observable.create(emitter -> {
            iterate(root, emitter);
            emitter.onComplete();
        });
    }

    private static void iterate(@NonNull View view, @NonNull ObservableEmitter emitter) {
        emitter.onNext(view);
        if (view instanceof ViewGroup) {
            ViewGroup viewGroup = (ViewGroup) view;
            for (int i = 0; i < viewGroup.getChildCount(); i++) {
                iterate(viewGroup.getChildAt(i), emitter);
            }
        }
    }
