如何使用hilt为ViewModel（通过调用创建ViewModel）注入RepositoryManager？

Question

这是我的存储库管理器

@Singleton
class RepositoryManager @Inject constructor(private val retrofit: Retrofit) {

    fun <T> obtainRetrofitService(serviceClass: Class<T>): T {
        return retrofit.create(serviceClass)
    }

}

class GankViewModel @ViewModelInject constructor() : BaseViewModel() {

    @Inject lateinit var repositoryManager: RepositoryManager

    fun getGankGirl() {
        repositoryManager.obtainRetrofitService(GankApi::class.java)
            .getGankGirls()
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribeWith(object : BaseObserver<GirlBean>() {
                override fun success(data: GirlBean) {
                    showLoading(true)
                }
            })
    }
}

@AndroidEntryPoint
class GankActivity : BaseActivity<ActivityGankBinding, GankViewModel>() {

    override fun init() {
        viewModel.getGankGirl()
    }

}

abstract class BaseActivity<VB : ViewBinding, VM : BaseViewModel> :RxFragmentActivity(),
    IBaseView {
    protected lateinit var binding: VB
    protected lateinit var viewModel: VM
    private val loading: BasePopupView by lazy {
        XPopup.Builder(this).asCustom(LoadingSimplePopup(this))
    }

    @Suppress("UNCHECKED_CAST")
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val type = javaClass.genericSuperclass as ParameterizedType
        val modelProvider = ViewModelProvider(this)

        val clazz0 = type.actualTypeArguments[0] as Class<VB>
        val method = clazz0.getMethod("inflate", LayoutInflater::class.java)
        binding = method.invoke(null, layoutInflater) as VB
        setContentView(binding.root)

        val clazz1 = type.actualTypeArguments[1] as Class<VM>
        viewModel = modelProvider.get(clazz1)

        init()

        viewModel.loadingEvent.observe(this, { isShow ->
            if (isShow) showLoading() else dismissLoading()
        })
    }

    abstract fun init()

    override fun showLoading() {
        if (!loading.isShow) {
            loading.show()
        }
    }

    override fun dismissLoading() {
        if (loading.isShow) {
            loading.dismiss()
        }
    }

}

和例外情况：

您只需要修复您的ViewModel

class GankViewModel @ViewModelInject constructor(var repositoryManager: RepositoryManager) : BaseViewModel() {
... }

如果你能再检查一遍
