Kodein 框架 - 属性 委托必须有一个 provideDelegate(...) 方法

Kodein Framework - property delegate must have a provideDelegate(...) method

我正在尝试构建具有以下架构的应用程序:LoginActivity -> MainActivity -> 在由 MainActivity 托管的片段中处理的所有其他内容。我也是第一次使用 Kodein 框架,在我的起始片段中出现以下错误:

Property delegate must have a 'provideDelegate(HomeFragment, KProperty*>' method. None of the following functions is suitable. provideDelegate(Context [highlighted in red], KProperty<>?) defined in org.kodein.di.android.KodeinPropertyDelegateProvider Type 'KodeinPropertyDelegateProvider' has no method 'getValue(HomeFragment, KProperty<>)' and thus it cannot serve as a delegate

到目前为止,这是我的代码:

class HomeFragment : Fragment(), KodeinAware {

override val kodein by kodein()
private val factory : MainViewModelFactory by instance()
private lateinit var viewModel: MainViewModel

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    // Inflate the layout for this fragment
    val binding : FragmentHomeBinding = FragmentHomeBinding.inflate(inflater, container, false)

    viewModel = ViewModelProviders.of(this, factory).get(MainViewModel::class.java)
    binding.viewModel = viewModel

    return binding.root
}

}

我该如何解决这个问题?

谢谢:)

没关系,在 kodein 完成后添加类型声明...:)

在您的导入中更改

import org.kodein.di.android.kodein

import org.kodein.di.android.x.kodein

你可以这样做:

override val kodein:Kodein by kodein()
