匕首2依赖项：
const deletedValuesfromArray =
[
{ "property_name": "Property three", "property_type": 4, "property_required": true, "property_origin": 2 },
{ "property_name": "rstywrtre", "property_type": 3, "property_required": true, "property_origin": 1 }
]
const normalArray =
[
{ "property_name": "Property one", "property_type": 4, "property_required": true, "property_origin": 1 },
{ "property_name": "Property two", "property_type": 5, "property_required": true, "property_origin": 1 },
{ "property_name": "Property three", "property_type": 4, "property_required": true, "property_origin": 2 },
{ "property_name": "rstywrtre", "property_type": 3, "property_required": true, "property_origin": 1 }
]
const result = normalArray.filter(obj => !deletedValuesfromArray.find(o => JSON.stringify(o) == JSON.stringify(obj)));
console.log(result);我的implementation "com.google.dagger:dagger:2.15"
kapt "com.google.dagger:dagger-compiler:2.15"
：
AppComponent我的@Singleton
@Component(modules = [
DomainModule::class,
DataModule::class,
PresentationModule::class,
ViewModelModule::class,
RepositoriesModule::class
])
interface AppComponent {
//reps
fun topicsRep(): TopicsRepository
fun countriesRep(): CountriesRepository
fun loginRep(): LoginRepository
}
班：
ViewModelModule我的@Module
abstract class ViewModelModule {
@Binds
internal abstract fun bindViewModelFactory(factory: ViewModelFactory): ViewModelProvider.Factory
@Binds
@IntoMap
@ViewModelKey(LoginViewModel::class)
internal abstract fun loginViewModel(viewModel: LoginViewModel): ViewModel
@Binds
@IntoMap
@ViewModelKey(CountriesViewModel::class)
internal abstract fun countriesViewModel(viewModel: CountriesViewModel): ViewModel
}
：
ViewModelFactory例如我的 @Suppress("UNCHECKED_CAST")
@Singleton
class ViewModelFactory
@Inject constructor(private val viewModels: MutableMap<Class<out ViewModel>,
@JvmSuppressWildcards Provider<ViewModel>>) :
ViewModelProvider.Factory {
override fun <T : ViewModel> create(modelClass: Class<T>): T = viewModels[modelClass]?.get() as T
}
@Target(AnnotationTarget.FUNCTION, AnnotationTarget.PROPERTY_GETTER, AnnotationTarget.PROPERTY_SETTER)
@kotlin.annotation.Retention(AnnotationRetention.RUNTIME)
@MapKey
internal annotation class ViewModelKey(val value: KClass<out ViewModel>)
和CountryComponent：
CountryModule我要实现的目标-我需要为我的活动和片段注入@ActivityScope
@Component(modules = [CountryModule::class], dependencies = [AppComponent::class])
interface CountryComponent {
fun inject(activity: SelectCountryActivity)
}
@Module
class CountryModule {
@Provides
@Singleton
fun provideCountriesInteractor(rep: CountriesRepository)
= SelectCountryInteractor(rep)
}
实例。我的视图模型包含其他依赖项。还要尝试为每个屏幕分离依赖项。
构建后出现错误：
ViewModelFactory将CountryComponent.java:10: error: java.util.Map<java.lang.Class<? extends android.arch.lifecycle.ViewModel>,javax.inject.Provider<android.arch.lifecycle.ViewModel>> cannot be provided without an @Provides-annotated method
java.util.Map<java.lang.Class<? extends android.arch.lifecycle.ViewModel>,javax.inject.Provider<android.arch.lifecycle.ViewModel>> is injected at ViewModelFactory.<init>(viewModels)
ViewModelFactory is injected at SelectCountryActivity.factory
SelectCountryActivity is injected at CountryComponent.inject(activity)
设置为ViewModelFactory时出错：
@Singleton是否有任何理由将ViewModel标记为CountryComponent scoped with @ActivityScope may not reference bindings with different scopes:
@dagger.Component(modules = {CountryModule.class}, dependencies = {AppComponent.class})
@Singleton class ViewModelFactory
AppComponent.java:6: error: AppComponent scoped with @Singleton may not reference bindings with different scopes:
@dagger.Component(modules = {DomainModule.class, DataModule.class, PresentationModule.class, ViewModelModule.class, RepositoriesModule.class})
或Singleton？
答案 0 :(得分：0)
通过添加
修复fun viewModelFactory(): ViewModelFactory
到我的AppComponent。
还从@Singleton
ViewModelFactory
