如何使用 insert-koin 在内容提供程序中注入数据存储库实例

Question

面临的问题在 AppModule 中插入 ContentProvider。

\n\n

我的应用程序级别模块是

\n\n

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

\n\n

我不知道如何在模块中使用 ContentProvider

\n\n

我已经尝试过代码

\n\n

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

\n\n

这在我的内容提供程序中，但在此之后我的应用程序启动崩溃\n并且 logcat 显示错误按摩

内容提供者初始化在Application()类中的onCreate()方法之前，我从Application()类中的attachBaseContext()方法调用了startKoin，在我的ContentProvider类中实现KoinComponent，并使用此在ContentProvider中注入数据存储库

 var dataRepo = inject<DataRepository>()

这是注入的代码

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)
