you can use the map operator to return a observable object that emits a new data type.For example above, subscriber does not care about the returned string, but rather the hash value of the string.Observable.just ("Hello, world!") . Map (new func1It's funny, isn't it? Our initial observable returned a string, and the final subscriber received an integer, which, of course, would further simplify the code by using lambda:Observable.just ("Hello, world!") . Map (S-s.hashcode ()) . Subscri

Objective Many people want to implement the Carousel diagram will think of using Viewpager + handler to complete the effect of the carousel diagram. But with the rapid development of Rxjava, Rxjava can be used instead of handler to accomplish such a task. Here we will introduce how to implement Rxjava+viewpager's Carousel diagram. The effect chart is as follow

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.

In the previous two articles, we introduced some basic concepts of rxjava and the simplest usage of rxjava. From this chapter, we start talking about the operators in Rxjava the operators in Operators,rxjava are divided into three main categories: Conversion class operator (map flatMap concatMap flatMapIterabl

First, what is RxJava?RxJava is a responsive programming framework that uses the observer design pattern. So naturally there are Observable and subscriber these two things.RxJava is an open source project, address: Https://github.com/ReactiveX/RxJavaThere is also a rxandroid, used for Android development, adding an interface for Android.

* * observable The interesting thing here is that lambda expressions are used. In the map transform, if the string is converted to an integer, the integer is returned without a problem, and the string is returned if the exception is reported. Similarly, at the end of a subscription, the type of the value parameter is also determined by the map transformation.Rxjava 2.x Implementation After the Rxjava 2.0
