RxJava学习(2)-订阅与取消订阅

前言

根据Froussios英文版的学习笔记，这里是简单的学习笔记。

一、Subscribe 订阅

Subscription    subscribe()
Subscription    subscribe(Action1 onNext)
Subscription    subscribe(Action1 onNext, Action1 onError)
Subscription    subscribe(Action1 onNext, Action1 onError, Action0 onComplete)
Subscription    subscribe(Observer observer)
Subscription    subscribe(Subscriber subscriber)

二、Unsubscribe取消订阅

boolean isUnsubscribed()
void unsubscribe()

三、Subscription

Subscription对象是被观察者和订阅者之间的桥梁。

1. Subscriptions.empty()返回一个什么都不做的Subscription对象。

Subscription empty = Subscriptions.empty();
 System.out.println(empty.isUnsubscribed()); // false
 empty.unsubscribe();
System.out.println(empty.isUnsubscribed()); // true

2. Subscriptions.from(Subscription... subscriptions)将一组订阅聚合到一起订阅和取消。
3. Subscriptions.unsubscribed()

Subscription unsubscribed = Subscriptions.unsubscribed();
System.out.println(unsubscribed.isUnsubscribed()); // true
