android - 如何使用 koin 依赖库在模块中注入(inject) Activity 上下文

Question

我有一个 Util 模块，如下所示，它需要 Activity 上下文 [而不是应用程序上下文] 来执行它的一些功能。

如何将 Activity 上下文注入(inject)其中？

class MainPresenter internal constructor(private val iMainActivity: IActivity)  : IPresenter {

    //dependencies
    private val context = iMainActivity as AppCompatActivity

    private var util = UtilModule(context)         //<-- inject this
    private var httpClient = HttpClient(context)   //<-- inject this

Answer 1

在本例中，为 @commonsware说了，presenter class 依赖于 activity 不好。更好的注入(inject)解决方案可以像下面的结构:

class IActivity{

    private val utilModule: UtilModule by lazy { UtilModule(this@IActivity) }
    private val httpClient: HttpClient by lazy { HttpClient(this@IActivity) }

    private val presenter: MainPresenter by inject{ parametersOf(utilModel, 
    httpClient) }

}

class MainPresenter(private val util: UtilModule, private val httpClient: HttpClient)

你的模块:

single { MainPresenter( it[0], it[1] ) }
