匕首2個模塊相互依賴

我有幾個相互依賴的類，GamePresenter和GameManager。我試圖注入它們使用構造函數注入，但我仍然無法弄清楚如何使它的工作，因爲我得到了依賴性循環錯誤。匕首2個模塊相互依賴

GameFragment應注入GamePresenter成片段，所以第一個就聊到了第二，而GameManager將被注入到GamePresenter。

GamePresenter是：

@Inject 
GamePresenter(GameRepository gameRepository, GameManager gameManager, GameContract.View view) { 
    DaggerGameManagerComponent.builder() 
      .gameManagerModule(new GameManagerModule(this)) 
      .build() 
      .inject(this); 

    this.view = view; 
    this.gameRepository = gameRepository; 
    this.gameManager = gameManager; 
}

GamePresenterModule是：

@Module 
public class GamePresenterModule { 
    private final GameContract.View view; 

    public GamePresenterModule(GameContract.View view) { 
     this.view = view; 
    } 

    @Provides 
    GameContract.View provideGameContractView() { 
     return view; 
    } 
}

GamePresenterComponent是：

@FragmentScoped 
@Component(dependencies = RepositoryComponent.class, modules = GamePresenterModule.class) 
public interface GamePresenterComponent { 
    void inject(GameFragment gameFragment); 
}

GameManager是：

@Inject 
public GameManager(GamePresenter gamePresenter, Game game) { 
    this.gamePresenter = gamePresenter; 
    this.game = game; 
}

GameManagerModule是：

@Module 
public class GameManagerModule { 
    private GamePresenter presenter; 

    public GameManagerModule(GamePresenter presenter) { 
     this.presenter = presenter; 
    } 

    @Provides 
    GameManager provideGameManager(Game game) { 
     return new GameManager(this.presenter, game); 
    } 

    @Provides 
    Game provideGame() { 
     return new Game(); 
    } 
}

GameManagerComponent是：

@FragmentScoped 
@Component(dependencies = GamePresenterComponent.class, modules = GameManagerModule.class) 
public interface GameManagerComponent { 
    void inject(GamePresenter gamePresenter); 
}

最後，GameFragment是：

@Override 
public void onCreate(@Nullable Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setRetainInstance(true); 

    DaggerGamePresenterComponent.builder() 
      .repositoryComponent(((GameApplication) getActivity().getApplication()).getRepositoryComponent()) 
      .gamePresenterModule(new GamePresenterModule(this)) 
      .build() 
      .inject(this); 
}

非常感謝提前！

當您遇到此類問題時，您應該過度考慮您的架構。

在這種情況下，我建議不要將GameManager注入GamePresenter。相反，使用GameManager所需的任何方法定義接口，讓GameManager實現它並在構造函數或提供程序中註冊它。

我該怎麼做？特別是「將其註冊到構造函數或提供者中」 – noloman
