java - android 中 RxJava2 中的 subscribe() 和 subscribeWith() 有什么区别？

Question

subscribe() 和subscribeWith() 在android 中的RxJava2 有什么区别？这两个函数都用于订阅 Observable 上的观察者。这两个功能之间的主要区别是什么？ 哪里用subscribe，哪里用subscribeWith。如果可能，请提供代码示例。

Answer 1

Since 1.x Observable.subscribe(Subscriber) returned Subscription, users often added the Subscription to a CompositeSubscription for example:

CompositeSubscription composite = new CompositeSubscription();

composite.add(Observable.range(1, 5).subscribe(new TestSubscriber<Integer>()));

Due to the Reactive-Streams specification, Publisher.subscribe returns void and the pattern by itself no longer works in 2.0. To remedy this, the method E subscribeWith(E subscriber) has been added to each base reactive class which returns its input subscriber/observer as is. With the two examples before, the 2.x code can now look like this since ResourceSubscriber implements Disposable directly:

CompositeDisposable composite2 = new CompositeDisposable();

composite2.add(Flowable.range(1, 5).subscribeWith(subscriber));
