通过Example来学习RxJava2 for Android

如何在Android 应用中使用RxJava2

如何从 RxJava 1 迁移到 RxJava 2

谁适合阅读这个项目 :

正在迁移到RxJava2的人
刚刚开始学习RxJava2的人

只需要构建编译这个项目，赶紧开始通过example来学习吧.

RxJava 2.0 has been completely rewritten from scratch on top of the Reactive-Streams specification. The specification itself has evolved out of RxJava 1.x and provides a common baseline for reactive systems and libraries.

Because Reactive-Streams has a different architecture, it mandates changes to some well known RxJava types.

Migration From RxJava 1 to RxJava 2

To allow having RxJava 1 and RxJava 2 side-by-side, RxJava 2 is under the maven coordinates io.reactivex.rxjava2:rxjava:2.x.y and classes are accessible below io.reactivex.

Users switching from 1.x to 2.x have to re-organize their imports, but carefully.

在你的app中引入RxJava2

在你的build.gradle中加入下面的代码

compile 'io.reactivex.rxjava2:rxjava:2.0.6'

如果你也正在用RxAndroid, 你还需要加入下面的代码

compile 'io.reactivex.rxjava2:rxandroid:2.0.1'

RxJava 2 Examples present in this sample project

RxJava 2.0 Example using CompositeDisposable as CompositeSubscription and Subscription have been removed.
RxJava 2 Example using Flowable.
RxJava 2 Example using SingleObserver, CompletableObserver.
RxJava 2 Example using RxJava2 operators such as map, zip, take, reduce, flatMap, filter, buffer, skip, merge, concat, replay, and much more:
RxJava 2 Android Samples using Function as Func1 has been removed.
RxJava 2 Android Samples using BiFunction as Func2 has been removed.
And many others android examples

简单来看一下RxJava2和RxJava1的区别

RxJava1 -> RxJava2

onCompleted -> onComplete - 没有了后面的字母 d
Func1 -> Function
Func2 -> BiFunction
CompositeSubscription -> CompositeDisposable
limit 这个操作符移除了，改用 - take in RxJava2
and much more.

操作符 :

Map -> transform the items emitted by an Observable by applying a function to each item
Zip -> combine the emissions of multiple Observables together via a specified function and emit single items for each combination based on the results of this function
Filter -> emit only those items from an Observable that pass a predicate test
FlatMap -> transform the items emitted by an Observable into Observables, then flatten the emissions from those into a single Observable
Take -> emit only the first n items emitted by an Observable
Reduce -> apply a function to each item emitted by an Observable, sequentially, and emit the final value
Skip -> suppress the first n items emitted by an Observable
Buffer -> periodically gather items emitted by an Observable into bundles and emit these bundles rather than emitting the items one at a time
Concat -> emit the emissions from two or more Observables without interleaving them
Replay -> ensure that all observers see the same sequence of emitted items, even if they subscribe after the Observable has begun emitting items
Merge -> combine multiple Observables into one by merging their emissions
