RxBus is a publish/subscribe event bus optimized for Android, like EventBus. RxBus Based on RxJava,it has a simple event bus as EventBus, but also the rich features of Rx Java.

How to use

1.Define EventData:

public static class EventData { /* Additional fields if needed */ }

2.Prepare subscribers: Declare and annotate your subscribing method, it will called in UI thread:

@RegisterBus
public void onEventData(EventData data) {/* Do something */};

3.Register and unregister your subscriber. For example on Android, activities and fragments should usually register according to their life cycle:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    initView();
    // register to RxBus
    RxBus.getInstance().register(this);
}

@Override
protected void onDestroy() {
    super.onDestroy();
    // unregister from RxBus
    RxBus.getInstance().unRegister(this);
}

3.Post events:

    // send data in thread
     Data data = new Data();
     Data.setContent("hello world");
     RxBus.getInstance().send(data);

Advantages other than EventBus

RxBus provides chainProcess method to wrap a process, and the results will be sent to the subscriber.

1. Chain process in model layer

    RxBus.getInstance().chainProcess(new Func1() {
        @Override
        public Object call(Object o) {
            // do something in IO thread, the return data can be subscribe and receive.
            // getUser() is a IO/net process
            User user = getUser();
            user.setId(uid);
            user.setName("大利猫");
            return user;
        }
    });
   

1. Then in UI thread:

       /**
        * @RegisterBus mark this method to receive data in UI thread
        * @param user
       */
   
       @RegisterBus
   
       public void onUser(User user) {
   
          userView.showUser(user);
   
       }
   

Gradle independence

Step 1. Add the JitPack repository to your build file, Add it in your root build.gradle at the end of repositories:

       allprojects {
           repositories {
               ...
               maven { url 'https://jitpack.io' }
           }
       }

Step 2. Add the dependency

       dependencies {
           compile 'com.github.liuguangli:RxBus:1.1'
       }
