RxBus

Event bus based on RxJava and optimized for Android.

Usage

We recommend obtaining the single instance of bus through injection or another appropriate mechanism.

Or get singleton like following:

Bus bus = BusProvider.getInstance();

Subscribing

To subscribe to an event, declare and annotate a method with @Subscribe. The method should be public and take only a single parameter.

@Subscribe
public void onEvent(SomeEvent event) {
    // TODO: Do something
}

You can also create subscription like following:

CustomSubscriber<SomeEvent> customSubscriber = bus.obtainSubscriber(SomeEvent.class,
    new Consumer<SomeEvent>() {
        @Override
        public void accept(SomeEvent someEvent) throws Exception {
            // TODO: Do something
        }
    })
    .withFilter(new Predicate<SomeEvent>() {
        @Override
        public boolean test(SomeEvent someEvent) throws Exception {
            return "Specific message".equals(someEvent.message);
        }
    })
    .withScheduler(Schedulers.trampoline());

Register and unregister your observer

To receive events, a class instance needs to register with the bus.

bus.register(this);

The customSubscriber also needs to register with the bus.

bus.registerSubscriber(this, customSubscriber);

Remember to also call the unregister method when appropriate.

bus.unregister(this);

Publishing

To publish a new event, call the post method:

bus.post(new SomeEvent("Message"));

Add RxBus to your project

Gradle:

compile 'com.github.anadea:rxbus:1.0.1'

Maven:

<dependency>
    <groupId>com.github.anadea</groupId>
    <artifactId>rxbus</artifactId>
    <version>1.0.1</version>
    <type>pom</type>
</dependency>

ProGuard

If you are using ProGuard, add the following lines to your ProGuard configuration file.

-keepattributes *Annotation*
-keepclassmembers class ** {
    @com.anadeainc.rxbus.Subscribe public *;
}
