Green Annotations
An Android Annotations plugin to support the Greenrobot Eventbus.
It can inject the default EventBus and automatically handle the registration/unregistration.
Usage in your Android Studio project:
In the build.gradle file of the module project:
dependencies {
// Android Annotations for Greenrobot
apt 'com.tmtron:green-annotations:1.0.2'
compile 'com.tmtron:green-annotations-api:1.0.2'
}Note: Green-Annotations version 1.0.2 requires Android-Annotations version 4.4.0
Details
Before
Shows the Activity without using AndroidAnnotations or GreenAnnotations:
public class ActivityBefore extends Activity {
EventBus eventBus;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
eventBus = EventBus.getDefault();
}
@Override
public void onStart() {
super.onStart();
eventBus.register(this);
}
@Override
public void onStop() {
eventBus.unregister(this);
super.onStop();
}
public void fireEvent(String message) {
eventBus.post(new MessageEvent(message));
}
@Subscribe(threadMode = ThreadMode.MAIN)
public void onMessageEvent(MessageEvent event) {
Toast.makeText(getApplicationContext(), event.message, Toast.LENGTH_SHORT).show();
}
}After
Shows the same Activity with AndroidAnnotations and GreenAnnotations:
@EActivity
public class ActivityAfter extends Activity {
@EventBusGreenRobot
EventBus eventBus;
public void fireEvent(String message) {
eventBus.post(new MessageEvent(message));
}
@Subscribe(threadMode = ThreadMode.MAIN)
public void onMessageEvent(MessageEvent event) {
Toast.makeText(getApplicationContext(), event.message, Toast.LENGTH_SHORT).show();
}
}Note: green-annotations-test is a tiny test-project: a sample android app with only one single activity to show how to use green-annotations (and the gradle-setup).
