Hilt Dagger 错误 java.lang.RuntimeException：无法创建 class HomeFragmentViewModel 的实例

Question

我试图将我的 viewModel 注入到片段中，但我遇到了这个错误：

java.lang.RuntimeException: 无法创建 class com.mas.cryptomasters.ui.fragment.home.HomeFragmentViewModel

的实例

我的代码：

class HomeFragment : BaseFragment<FragmentHomeBinding>() {

    private val viewModel: HomeFragmentViewModel by viewModels()

    override fun init() {

        viewModel.homeMutable.observe(this) {
            when {
                it.reLogin -> requireActivity().reLogin()
                it.error.isNotEmpty() -> requireContext().crToast()
                it.data != null -> Log.e("TAG", "data != null")
            }
        }
    }
}

这是我的 ViewModel class

@HiltViewModel
class HomeFragmentViewModel @Inject constructor(apiRepository: ApiRepository) :
    ViewModel() {
    val homeMutable: MutableLiveData<Response> = MutableLiveData()

    init {
        viewModelScope.launch {
            apiRepository.getHome()
                .let {
                    when (it.isRequestSuccess(it.body()!!.code)) {
                        RESPONSE.SUCCESS -> homeMutable.postValue(Response(it.body()!!))
                        RESPONSE.ERROR -> homeMutable.postValue(Response(error = "${it.errorBody()}"))
                        RESPONSE.AUT -> homeMutable.postValue(Response(reLogin = true))
                    }
                }
        }
    }
}

确保您的 activity 和片段有 @AndroidEntryPoint 注释。
将 implementation "androidx.fragment:fragment-ktx:1.4.1" 添加到 build.gradle(:app)
