Introduction to Android RxJava (2) Operators of RxJava In the previous article, we used a simple example to show you the basic usage of RxJava. I believe that you have a general understanding of RxJava. Since the previous article introduced the use of

compose (). FlatMap () has many uses and this is not one of the them. Referenced from: http://blog.danlew.net/2015/03/02/dont-break-the-chain/To put it simply:1, compose is affecting the entire stream, and Flatmap is only the part that affects its own transformation.2. Flatmap is executed after calling next (), while compose is executed directly.3, Flatmap in next () after the execution will create a observable object (for the next operation to form a chain structure), and compose more like st

data structures.2. A function that receives the data structure generated by the first function and the data emitted by the source observable as a parameter.Let's use the reduce and collect operators. As with the original scan example, we created the source observable using a list of 10 numbers 2.private observable return observable.from (list ). reduce ((x, y) x * y) ; } private observable arraylist integer >> collectobserver () {return observablefrom . collect (() n

how broken. It's really not a good thing:fetchUsersFromDatabase() .zipWith(fetchSomethingElseFromDatabase(), (users, somethingElse) -> { /*here combine users and something else into a new object*/ }) .subscribe( o -> { /*use the combine object from users and something else to fill the adapter */});As above, we can easily combine other data found in the database with the users to show a adapter together. Is it easier to maintain, less code, easier to re

Rxjava Starter Series four, responsive programming in AndroidIn the introductory series, I've basically introduced how Rxjava is used. But as an Android developer, how do you make Rxjava work for you? This blog I will introduce to Android development for the

Preface Rxjava and Rxandroid (https://github.com/ReactiveX/RxAndroid) have been burning for a while, and here is a brief introduction to them. Rxjava's self-introduction on the GitHub homepage is "A library for composing asynchronous and event-based the using programs observable for th e java VM (a library that uses an observable sequence on a Java VM to compose an asynchronous, event-based program). In fact, it has become a responsive Third-party lib

architecture distributes data through interface callbacks, and the response MVP obtains observable data through observable.If you combine the retrofit network framework, which response MVP model layer data source. Is that it can be servicegenerator.Retrofit static Construction method constructs the network Request object, the incoming interface, the proxy pattern generates the data, the P layer can directly obtain the data.Of course this is just my initial idea, intended to be used in my person

Rxjava, because of its chain call based on event flow, logic simple easy to use features, by the major Android developers welcome.GithubIf you do not know RxJava, see the article: Android: This is a clear understandable RxJava Getting Started tutorialThe reason why

RxJava is becoming more popular in Android application development, but because of its higher threshold, the initial use inevitably encounters many problems, such as those described in RxJava Common error usage and situations where RxJava should not be used. To avoid these common problems, many folk experts have develo

Rxjava is the newest and most commonly used, and one of the most favorite frameworks for the program's members.The core of Rxjava consists of observable (the observer, the source of the event) and Subscriber (The observer), observable is responsible for issuing a series of events, subscriber handling these events.A observble can issue 0 or more events until the end or error occurs. Each occurrence of an eve

Android Rxjava+retrofit Network exception capture, state code unified processing Preface Recently using Rxjava+retrofit for development, in the project encountered such a requirement, when the networking request to obtain data anomalies, the corresponding message and statuscode need to be obtained and displayed, such as:1.
