Android碎碎念 -- EventBus3.0

1、概述

EventBus是一款針對Android優化的發佈/訂閱事件總線。主要功能是替代Intent,Handler,BroadCast在Fragment，Activity，Service，線程之間傳遞消息.優勢是開銷小，代碼更優雅。以及將發送者和接收者解耦。

一、下載EventBus的類庫
源碼：https://github.com/greenrobot/EventBus

二、基本使用

(1).Define events:

public class MessageEvent { /* Additional fields if needed */ }

(2).Prepare subscribers
Register your subscriber (in your onCreate or in a constructor):

eventBus.register(this);

(3).Declare your subscribing method:

@Subscribe
public void onEvent(AnyEventType event) {/* Do something */};

(4).Post events:

eventBus.post(event);

三、checking

Gradle:

compile 'org.greenrobot:eventbus:3.0.0'

Maven:

<dependency> <groupId>org.greenrobot</groupId> <artifactId>eventbus</artifactId> <version>3.0.0</version> </dependency>
