android – 如何使用Dagger dependecies提供活动上下文？

如何在mainModule类中提供活动上下文？谢谢！代码如下所示：

@Singleton
@Component(modules = {AndroidInjectionModule.class,AppModule.class,ActivityBuilder.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {

        @BindsInstance
        Builder application(Application application);

        AppComponent build();

    }

    void inject(MvmApp app);
}

Activtity builder：

@Module
public abstract class ActivityBuilder {

    @ContributesAndroidInjector(modules = {MainModule.class})
    abstract MainActivity bindMainActivity();
}

我有一个appModule,每个活动都有一个模块：

@Module
public class AppModule {

    @Provides
    @Singleton
    @ApplicationContext
    Context provideContext(Application application) {
        return application;
    }

    @Provides
    @Singleton
    DataManager provideDataManager(AppDataManager appDataManager) {
        return appDataManager;
    }

    @Provides
    @DatabaseInfo
    String provideDatabaseName() {
        return "carDatabase";
    }

    @Provides
    @Singleton
    AppDataBase provideAppDatabase(@DatabaseInfo String dbName,@ApplicationContext Context context) {
        return Room.databaseBuilder(context,AppDataBase.class,dbName)
                .build();
    }

    @Provides
    @Singleton
    DbHelper provideDbHelper(AppDbHelper appDbHelper) {
        return appDbHelper;
    }
}

AppClass：

public class MvmApp extends Application implements HasActivityInjector {

    @Inject
    DispatchingAndroidInjector<Activity> activityDispatchingAndroidInjector;

    @Override
    public void onCreate() {
        super.onCreate();

        DaggerAppComponent.builder()
                .application(this)
                .build()
                .inject(this);

    }

    @Override
    public DispatchingAndroidInjector<Activity> activityInjector() {
        return activityDispatchingAndroidInjector;
    }
}

我的所有活动都扩展了基础活动,注入了Dagger家属.

public abstract class BaseActivity extends AppCompatActivity implements MvpView {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        AndroidInjection.inject(this);

    }
}

在mainModule中,我需要提供活动的上下文.

@Module
public class MainModule {

    @Provides
    MainMvpPresenter<MainMvpView> provideMainPresenter(
            MainPresenter<MainMvpView> presenter) {
        return presenter;
    }



    @Provides
    CompositeDisposable provideCompositeDisposable() {
        return new CompositeDisposable();
    }

    @Provides
    CarAdapter provideCarAdapter( @ActivityContext Context context) {
        return new CarAdapter(context);
    }

}

解决方法

解决方案是：

@Module
public class MainModule {

    @Provides
    MainMvpPresenter<MainMvpView> provideMainPresenter(
            MainPresenter<MainMvpView> presenter) {
        return presenter;
    }

    @Provides
    CompositeDisposable provideCompositeDisposable() {
        return new CompositeDisposable();
    }

    @Provides
    CarAdapter provideCarAdapter(MainActivity activity) {
        return new CarAdapter(activity);
    }

}
