注入活动问题（Dagger2）

Question

我一直在尝试注入我的活动，由于某种原因，它似乎不起作用。如果我从DaggerAppCompatActivity扩展我的活动或直接在我的活动中实现HasAndroidInjector，这似乎不起作用。

错误

组件

@Singleton
@Component(
    modules = [
        AccountCreationActivityBuilderModule::class,
        AndroidInjectionModule::class],
    dependencies = [AccountCreationFeature.Dependencies::class]
)
interface AccountCreationComponent : AndroidInjector<AccountCreationFeatureImpl> {

    @Component.Factory
    interface Factory {
        fun create(
            @BindsInstance testFeatureImpl: AccountCreationFeatureImpl,
            accountCreationFeature: AccountCreationFeature.Dependencies
        ): AccountCreationComponent
    }
}

AccountCreationFeatureImpl

class AccountCreationFeatureImpl : AccountCreationFeature {

    private lateinit var accountCreationComponent: AccountCreationComponent

    override fun inject(dependencies: AccountCreationFeature.Dependencies) {
        if (::accountCreationComponent.isInitialized) {
            return
        } else{
            accountCreationComponent = DaggerAccountCreationComponent.factory().create(this, dependencies)
        }
    }
}

ActivityBuilderModule

@Suppress("unused")
@Module
abstract class AccountCreationActivityBuilderModule {

    @ContributesAndroidInjector(modules = [AccountCreationFragmentBuilderModule::class])
    abstract fun contributeTestActivity(): TestActivity
}

FragmentBuilderModule

@Suppress("unused")
@Module
abstract class AccountCreationFragmentBuilderModule {

    @ContributesAndroidInjector
    abstract fun contributesTestFragment(): TestFragment
}

活动

class TestActivity : DaggerAppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_test)
    }
}

片段

class TestFragment : DaggerFragment() {

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_blank, container, false)
    }
}
