android - 如何使用 insert-koin 在内容提供者中注入(inject)数据存储库实例

Question

面临的问题是在 AppModule 中插入 ContentProvider。

我的应用级模块是

module {
        single { TinyDB.getInstance(get()) }
        single { DataRepository(get()) }
        viewModel { HomeViewModel(get()) }
    }

我不知道如何在模块中使用 ContentProvider

我试过代码

val dataRepo = inject(DataRepository::class.java) 

这在我的内容提供者中，但在此之后我的应用程序开始崩溃 和 logcat 显示错误消息

Answer 1

Content Provider Initialise 在 Application() 类中的 onCreate() 方法之前，我已经从 Application() 类中的 attachBaseContext() 方法调用了 startKoin，在我的 ContentProvider 类中实现了 KoinComponent 并使用它在 ContentProvider 中注入(inject)数据存储库

 var dataRepo = inject<DataRepository>()

注入(inject)代码

inline fun <reified T : Any> inject(name: String = "", scope: Scope? = 
null, noinline parameters: ParameterDefinition = 
emptyParameterDefinition()) = lazy { get<T>(name, scope, parameters) }

inline fun <reified T : Any> get(name: String = "", scope: Scope? = 
null, noinline parameters: ParameterDefinition = e . 
mptyParameterDefinition()): T = getKoin().get(name, scope, parameters)
//
fun getKoin(): KoinContext = 
(org.koin.standalone.StandAloneContext.koinContext as KoinContext)
