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 *;
}
