DeliveryReplay is weird

[lectricas]

Hi. What I want is to turn RxBinding callback back to my acitivity. Restartable is not suitable for that, however I need my view object in order to call the callback method. getView is depricated, so I tried to use deliveryFirst:

    public void listenFieldsForClick(Observable<Void> clicksFrom, Observable<Void> clicksTo) {
        deliverReplay().call(clicksFrom.map(aVoid -> aVoid)).subscribe(
                delivery -> delivery.split(SelectRouteFragment::clearEditTextFrom, this::onError)
        );

        deliverReplay().call(clicksTo.map(aVoid -> aVoid)).subscribe(
                delivery -> delivery.split(SelectRouteFragment::clearEditTextFrom, this::onError)
        );
    }

so this is my method, which listens fields for click event by RxView.clicks(myview);

And... this seems kinda huge for just one simple callback. RestartableFirst for example make more actions and code looks better and more readable. Second< I have to do this map call (clicksFrom.map(aVoid -> aVoid)) bacause call somehow don't understand that I'm passing an object there. What I'm doing wrong?

In Nucleus presenter is not supposed to control view.

Controlling view (if you really need it) with Rx is weird as I personally think, because Rx is more complex than simple method calls.

@konmik , but what about rxbinding? I think it's nice to get rid of logic in my activity. I took this project as an example https://github.com/matzuk/TestableCodeMobius Can you show your way of handling the scenario when button status depends on editText status?

[konmik]

I have no idea how and why someone will need to control presenter from view with rx(bindings) to control view from presenter back. This type of ping-pong logic is not efficient. There many ways to split the app logic into parts, and ping-pong is the most complicated and less efficient one.

@konmik I agree that bindings require more code and sometimes unreadable. can you please show some examples of how to split the logic?
