匕首2三部分注射的Android [英] Dagger 2 Third part Injection Android
问题描述
嗨即时试图找出如何做一个干净的第三方注入。我想正确注入奥托巴士到我的工作和活动。
四看出，您可以使用构造函数注入，但因为我没有与Android的构造，我不知道我怎么能那么注入我的公交车。
Hi im trying to figure out how to do a clean third party injection. I want to inject Otto bus properly into my services and activities. Iv seen that you can use inject on constructor, but since I dont have any constructor with Android, i wonder how I can then inject my bus.
㈣创建一个模块，它提供了总线的新实例。 IV还创造了它可以对总线对象的接口的组件。
Iv created a module which provides a new instance of the bus. Iv also created a component which has an interface for the Bus object.
但我怎么能得到这个注入，我应该在哪里开始我的图表？
But how can I get this injected and where should I initiate my graph?
由于从匕首1 objectGraph被删除，我用匕首_....组件并创建（）的应用程序类，但我应该怎么把它注射到任何活动或服务？
Since the objectGraph from Dagger 1 is removed, i use the Dagger_.... component and create() in the application class, but how should I inject it into whatever activity or service?
我应该建立在每一个的onCreate组件，并从那里得到的公交车？或者是有可能像@注入1匕首？请告诉我，因为现在它似乎更块状和复杂得多做的匕首1路。
Should I create the component in every onCreate and get the bus from there? Or is it possible to @Inject like Dagger 1? Please tell me because right now it seems much more clumpy and complicated than Dagger 1 way of doing it.
@Component(modules = EventBusModule.class)
@Singleton
public interface EventBus {
Bus bus();
}
@Module
public class EventBusModule {
@Provides
@Singleton
public Bus provideBus() {
return new Bus(ThreadEnforcer.ANY);
}
}
所有我希望能够做的是：
All i want to be able to do is:
public class WearService extends WearableListenerService {
private static final String TAG = WearService.class.getSimpleName();
@Inject
protected Bus bus;
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
bus.register(this);
return START_STICKY;
}
}
我看看下面这个例子（ https://github.com/LiveTyping/u2020-mvp），并看到它的可能，但不知道事情是怎么挂在一起。
I look at this example(https://github.com/LiveTyping/u2020-mvp) and see that its possible, but not sure how things is hanging together.

它非常审慎和职位不同的解决方案，以我的问题。
Its very deliberate and posts different solutions to my issue.
