android - 在android中使用MVP模式时，android服务调用和对GoogleAPIClient的调用应该写在哪里？

Question

我正在尝试通过引用此链接在我的 android 项目中实现 MVP 模式:https://github.com/jpotts18/android-mvp

我已经成功地实现了view/presenter/interactor 类。不清楚

• 将服务调用代码放在哪里？

Since i cannot get the context inside the presenter or interactor class, I am not able to put the service call there

• 在哪里实现 GoogleApiClient 类？

Since GoogleApiClient also requires context to run, it also cannot be implemented inside the presenter or interactor without a context

使用 dagger 可以更轻松地将 Interactor 注入(inject) Presenter。试试这个链接(https://github.com/spengilley/AndroidMVPService)

我正在尝试不使用 Dagger 来实现它。但这似乎违反了 MVP 架构。

我从 Activity 创建了一个 Interactor 实例。然后使用 Interactor 作为参数之一创建 Presenter 实例。

Activity

public class SomeActivity extends Activity implements SomeView {
   private SomePresenter presenter;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      SomeInteractor interactor = new SomeInteractorImpl(SomeActivity.this);
      presenter = new SomePresenterImpl(interactor,this);
   }

   @Override
   protected void onStart() {
     super.onStart();
     presenter.startServiceFunction();
   }

演示者

public interface SomePresenter {
   public void startServiceFunction();
}

Presenter 实现

public class SomePresenterImpl implements SomePresenter {
   private SomeInteractor interactor;
   private SomeView view;
   public SomePresenterImpl(SomeInteractor interactor,SomeView view){
      this.interactor = interactor;
      this.view = view;
   }
   @Override
   public void startServiceFunction() {
      interactor.startServiceFunction();
   }
}

交互者

public interface SomeInteractor {
   public void startServiceFunction();
}

交互器实现

public class SomeInteractorImpl implements SomeInteractor {
   private Context context;

   public SomeInteractorImpl(Context context) {
      this.context = context;
   }

   @Override
   public void startServiceFunction() {
      Intent intent = new Intent(context, SomeService.class);
      context.startService(intent);
   }
}
