android - 带有 Hilt 的 Dagger 从模块中的适配器中注入(inject) ActivityContext

Question

我正在使用 Dagger 和刀柄，我想将 @ActivityContext 从模块注入(inject)到适配器，但我收到了这个错误 -

ANTLR Tool version 4.5.3 used for code generation does not match the current runtime version 4.7.1ANTLR Runtime version 4.5.3 used for parser compilation does not match the current runtime version 4.7.1ANTLR Tool version 4.5.3 used for code generation does not match the current runtime version 4.7.1ANTLR Runtime version 4.5.3 used for parser compilation does not match the current runtime version 4.7.1/mnt/My Projects/app/build/generated/source/kapt/debug/app/myapp/MyApp_HiltComponents.java:156: error: [Dagger/MissingBinding] @dagger.hilt.android.qualifiers.ActivityContext android.content.Context cannot be provided without an @Provides-annotated method.
  public abstract static class ApplicationC implements MyApp_GeneratedInjector,
                         ^
      @dagger.hilt.android.qualifiers.ActivityContext android.content.Context is injected at
          app.myapp.di.modules.activitiesModules.HomeActivityModule.provideAdapterFragmentState(context)

          app.myapp.ui.home.HomeActivity.adapterFragmentState
      app.myapp.ui.home.HomeActivity is injected at

这是我的 HomeActivityModule -

@Module
@InstallIn(ActivityRetainedComponent::class)
object HomeActivityModule {

    @Provides
    @ActivityRetainedScoped
    fun provideAdapterFragmentState(@ActivityContext context: Context): AdapterFragmentState {
        return AdapterFragmentState(context)
    }

}

这是我的适配器 -

@ActivityRetainedScoped
class AdapterFragmentState @Inject constructor(@ActivityContext context: Context)
    : FragmentStateAdapter(context as AppCompatActivity){

哪一部分是错的？

Answer 1

@Module
@InstallIn(ActivityComponent::class)
object HomeActivityModule {

    @Provides
    @ActivityScoped
    fun provideAdapterFragmentState(@ActivityContext context: Context): AdapterFragmentState {
        return AdapterFragmentState(context)
    }

}

编辑:
因为 ActivityRetainedComponent 存在于配置更改中，而 ActivityComponent 没有。
如果你想注入(inject)@ActivityContext，你的模块应该安装在ActivityComponent中，并且注入(inject)的对象必须是@ActivityScoped。
