Event Bus By RxJava.

RxBus - An event bus by ReactiveX/RxJava/ReactiveX/RxAndroid

This is an event bus designed to allowing your application to communicate efficiently.

I have use it in many projects, and now i think maybe someone would like it, so i publish it.

RxBus support annotations(@produce/@subscribe), and it can provide you to produce/subscribe on other thread like MAIN_THREAD, NEW_THREAD, IO, COMPUTATION, TRAMPOLINE, IMMEDIATE, even the EXECUTOR and HANDLER thread, more in EventThread.

Also RxBus provide the event tag to define the event. The method's first (and only) parameter and tag defines the event type.

Usage

Just 2 Steps:

STEP 1

Add dependency to your gradle file:

compile 'com.hwangjr.rxbus:rxbus:1.0.5'

Or maven:

<dependency>
  <groupId>com.hwangjr.rxbus</groupId>
  <artifactId>rxbus</artifactId>
  <version>1.0.5</version>
  <type>aar</type>
</dependency>

TIP: Maybe you also use the JakeWharton/timber to log your message, you may need to exclude the timber (from version 1.0.4, timber dependency update from AndroidKnife/Utils/timber to JakeWharton):

compile ('com.hwangjr.rxbus:rxbus:1.0.5') {
    exclude group: 'com.jakewharton.timber', module: 'timber'
}

en Snapshots of the development version are available in Sonatype's snapshots repository.

STEP 2

Just use the provided(Any Thread Enforce):

com.hwangjr.rxbus.RxBus

Or make RxBus instance is a better choice:

public static final class RxBus {
    private static Bus sBus;

    public static synchronized Bus get() {
        if (sBus == null) {
            sBus = new Bus();
        }
        return sBus;
    }
}

Add the code where you want to produce/subscribe events, and register and unregister the class.

public class MainActivity extends AppCompatActivity {
    ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        RxBus.get().register(this);
        ...
    }

    @Override
    protected void onDestroy() {
        ...
        RxBus.get().unregister(this);
        ...
    }

    @Subscribe
    public void eat(String food) {
        // purpose
    }

    @Subscribe(
        thread = EventThread.IO,
        tags = {
            @Tag(BusAction.EAT_MORE)
        }
    )
    public void eatMore(List<String> foods) {
        // purpose
    }

    @Produce
    public String produceFood() {
        return "This is bread!";
    }

    @Produce(
        thread = EventThread.IO,
        tags = {
            @Tag(BusAction.EAT_MORE)
        }
    )
    public List<String> produceMoreFood() {
        return Arrays.asList("This is breads!");
    }

    public void post() {
        RxBus.get().post(this);
    }

    public void postByTag() {
        RxBus.get().post(Constants.EventType.TAG_STORY, this);
    }
    ...
}

That is all done!
