Annotation Type Presenter

@Retention(value=RUNTIME)
 @Target(value=FIELD)
public @interface Presenter

Annotation to inject the presenter that already defined in a ActivityView.presenter(), a FragmentView.presenter() or a CustomView.presenter().

It must be applied into the view implementation classes (Activity, Fragment or Custom View), otherwise it won't work.

You have access to the presenter instance after super call in Activity.onCreate(Bundle), Fragment.onActivityCreated(Bundle) and View.onAttachedToWindow() methods. Also during configuration changes, same instance of presenter will be injected.

Here is an example:

  @FragmentView(presenter = MyPresenter.class)
  public class MyFragment extends Fragment{
      @Presenter
      MyPresenter presenter;

  }

  public class MyPresenter extends AbstractPresenter<MyView>{

  public MyPresenter(){

  }
 }

 interface MyView{

  }
 

By default you can't pass any objects to the constructor of presenters, but you can use Dagger to inject presenters.

Here is an example of using dagger:

  @FragmentView(presenter = MyPresenter.class)
  public class MyFragment extends Fragment{

      @Inject
      @Presenter
      MyPresenter presenter;

      @Override
      void onCreate(Bundle b){
          SomeComponent.injectTo(this);
      }
  }

  public class MyPresenter extends AbstractPresenter<MyView>{

  public MyPresenter(){

  }
 }
 interface MyView{

  }
