Third-party frameworks used by the AndroidAnnnotations injection framework integrate the Otto event bus (14th)

 

 

This article is from: [Jiang qingqing's blog]

(1). Preface:

We have already explained how to integrate the AndroidAnnotations framework with RoboGuice. Today we will start to learn more about integrating the third-party framework with the Otto event bus. The Otto event bus is similar to the Eventbus we often use. Otto Official Website: decoupling ).

 

(2). Integration of Otto and AndroidAnnotations

• Integrate the AndroidAnnotations framework into the project (for details, see [FastDev4Android framework development] AndroidAnnnotations injection framework introduction and basic configurations of Android Studios (7)
• Integrate the otto framework into the project (for details, please refer to the http://square.github.io/otto/) here to talk about AndroidStudio Configuration:

  Dependencies {

  Compile 'com. squareup: otto: 1.3.8'

  }

  • Use @ EBean to create a singleton class for the event Bus
  • Create an event class for transmission and distribution through the event Bus
  • Use bus. post () to send events to the event bus
  • Use @ Subscribe for annotation to obtain published events

    The following example indicates that the title of the notification Activity is updated by Fragment:

     

    // Declare the busas an enhanced bean@EBean(scope =Scope.Singleton)public class OttoBusextends BasicBus { }public classUpdateTitleEvent {         public final String title;         public UpdateTitleEvent(String title) {                this.title = title;        } }

    
    

    @EActivity(R.layout.hello_activity)public classHelloAndroidActivity extends FragmentActivity {         @Bean        OttoBus bus;         @Override        protected void onCreate(BundlesavedInstanceState) {               super.onCreate(savedInstanceState);                bus.register(this);        }         @Override        protected void onDestroy() {                super.onDestroy();                bus.unregister(this);        }     @Subscribe    public void onUpdateTitle(UpdateTitleEventevent) {        setTitle(event.title);    } }

    
    

    @EFragment(R.layout.hello_fragment)public classHelloFragment extends Fragment {     int counter = 1;     @Bean    OttoBus bus;     @Click    void fragmentButtonClicked() {        bus.post(newUpdateTitleEvent(Clicks:  + counter++));    }}

    At this point, Otto integration for third-party framework integration of AndroidAnnotations has been fully explained.
