Android 空数据来自改装

我正在写一份有关货币的申请. 接收到空数据(Json正常). 我试着调试它，但我不知道错误在哪里，是什么错误. 如果你能帮助我了解错误在哪里，我将不胜感激. 以下是我的代码:

ApiService:你是什么意思？

interface ApiService {

    @GET("daily_json.js")
    suspend fun getValute(): Response<Valute>
}

Retrofit实例:

object RetrofitInstance {

    private val retrofit by lazy {
        Retrofit.Builder().baseUrl("https://www.cbr-xml-daily.ru/")
            .addConverterFactory(GsonConverterFactory.create())
            .build()
    }
    val api: ApiService by lazy {
        retrofit.create(ApiService:你是什么意思？:class.java)
    }
}

存储库:

class Repository {

    suspend fun getVal(): Response<Valute>{
        return RetrofitInstance.api.getValute()
    }

}

视图模型:

class Start视图模型: ViewModel() {

    var repo = Repository()
    val moneyList: MutableLiveData<Response<Valute>> = MutableLiveData()


    fun getMoney(){
        viewModelScope.launch {
            moneyList.value = repo.getVal()
        }
    }
}

片段:

       class StartFragment : Fragment() {
        private lateinit var _binding: FragmentStartBinding
        private val binding get() = _binding!!
        private val adapter = StartAdapter()
    
        override fun onCreateView(
            inflater: LayoutInflater, container: ViewGroup?,
            savedInstanceState: Bundle?
        ): View? {
            _binding = FragmentStartBinding.inflate(inflater, container, false)
            val view = binding.root
    
    
            return view
    
        }
    
    
        override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
            super.onViewCreated(view, savedInstanceState)
    
            binding.rvStart.adapter = adapter
            val viewModel = ViewModelProvider(this).get(Start视图模型::class.java)
            viewModel.getMoney()
            viewModel.moneyList.observe(viewLifecycleOwner,{list ->
                list.body()?.let { adapter.setList(it) }
            })
}

适配器:

class Start适配器: RecyclerView.Adapter<StartAdapter.StartHolder>() {

    var listValute = emptyList<Valute>()

class StartHolder(item: View): RecyclerView.ViewHolder(item) {

    val binding = ItemBinding.bind(item)

    fun bind(valute: Valute) = with(binding){

        nameMoney.text = valute.CharCode
        purchase.text = valute.Value.toString()

    }
}

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): StartHolder {
        val view = LayoutInflater.from(parent.context).inflate(R.layout.item, parent, false)
        return StartHolder(view)
    }

    override fun getItemCount(): Int {
        return listValute.size
    }

    override fun onBindViewHolder(holder: StartHolder, position: Int) {
        holder.bind(listValute[position])
    }

    fun setList(valute: Valute){
        listValute = listOf(valute)
        notifyDataSetChanged()
    }
}

我附上了你可能需要的所有代码.

Update个 我忘了添加DataClass

data class Valute(
    val CharCode: String,
    val ID: String,
    val Name: String,
    val Nominal: Int,
    val NumCode: String,
    val Previous: Double,
    val Value: Double
): Serializable
