RxJava 2.0is open source extension to java for asynchronous programming by NetFlix. It is much closer to functional programming as seen injava 8 lambda expressions. The basic building blocks of reactive code areObservablesandSubscribers. AnObservableemits items; aSubscriberconsumes those items. RxJav...

RxJava丰富的操作符,再结合Observable与Subscribe能够很好的解决异步嵌套回调问题。但是它的使用成本就相对提高了,你要对它的操作符要非常了解,避免在使用过程中滥用或者过度使用,这样自然复杂度就提升了。 那么我们渴望的解决方案是能够更加简单、全面与健壮,而我们今天的主题Coroutine就能够达到这种效果。 Coroutine在Kotlin...
Starting with a high-level understanding, we will gradually move deeper into how RxJava works. Along the way, we will learn about reactive patterns and tricks to solve common problems programmers encounter. In Chapter 2, The Observable and Subscribers, Chapter 3, Basic Operators, and Chapter 4...

Cold Observables in RxKotlin: Cold observables in RxKotlin, like in other Rx libraries, emit items when there is a subscriber. Each subscriber receives its own independent sequence of items. When a new subscriber subscribes, it starts receiving items from the beginning of the sequence. ...
Chapter 12, Asynchronous Programing with RxJava, we will introduce RxJava, a library used to easily compose asynchronous and event-based tasks on Java by using observable data streams.目录 上一章 下一章首页 书籍详情 目录 听书 自动阅读00
Well, let’s give it a try. This is the same example, rewritten using RxJava: @Override public void onStart() { super.onStart(); Observable.fromCallable(() -> { while (true) { Log.d("RxJava", "count: " + counter.get);
