android - Dagger 无法注入(inject)类型参数字段

Question

我正在开发一个 android 应用程序，我正在尝试注入(inject)一个在抽象类中类型参数化的字段:BaseListFragment

public abstract class BaseListFragment<E, A extends ArrayAdapter<E>, S> extends BaseFragment
{
    @Inject protected S service;
}

但我在编译时遇到以下错误: 错误:找不到符号类 S

这是我的 BaseFragment 代码:

public class BaseFragment extends Fragment
{
    @Override public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        ((App) getActivity().getApplication()).inject(this);
    }
}

这是我的服务模块:

@Module(
        complete = false,
        library = true
)
public class ServiceModule
{
    @Provides @Singleton BucketService provideBucketService(RestAdapter restAdapter)
    {
        return restAdapter.create(BucketService.class);
    }

    @Provides @Singleton ProjectService provideProjectService(RestAdapter restAdapter)
    {
        return restAdapter.create(ProjectService.class);
    }

    @Provides @Singleton ShotService provideShotService(RestAdapter restAdapter)
    {
        return restAdapter.create(ShotService.class);
    }

    @Provides @Singleton TeamService provideTeamService(RestAdapter restAdapter)
    {
        return restAdapter.create(TeamService.class);
    }

    @Provides @Singleton UserService provideUserService(RestAdapter restAdapter)
    {
        return restAdapter.create(UserService.class);
    }
}

下面是一个扩展 BaseListFragment 类的例子:

public class ProjectFragment extends BaseEntityFragment<Project, ProjectViewAdapter, ProjectService>
{
}

有没有办法注入(inject)参数化类型？

问候，

从 2.0.1 版开始，Dagger 2 可以 support您所说的注入(inject)类型。看看GenericTest对于所有各种排列。
