Question

面对在ArrayList中获取响应的问题。

我有以下Respose on String value

 var res_message: String = ""
 res_message = "${result.vehicletypes} "

获取此字符串上的值

     [VehicleType(_id=1, vehicleType=Hatchback, __v=0), 
      VehicleType(_id=2, vehicleType=Maruti, __v=0), 
      VehicleType(_id=3, vehicleType=Honda, __v=0), 
      VehicleType(_id=4, vehicleType=Bike, __v=0)]

改造结果

 vehicletypes = {ArrayList@6055}  size = 4
 0 = {Model$VehicleType@6058} "VehicleType(_id=1, 
vehicleType=Hatchback, __v=0)"
 1 = {Model$VehicleType@6059} "VehicleType(_id=2, 
 vehicleType=Maruti, __v=0)"
  2 = {Model$VehicleType@6060} "VehicleType(_id=3, 
 vehicleType=Honda, __v=0)"
  3 = {Model$VehicleType@6061} "VehicleType(_id=4, 
  vehicleType=Bike, __v=0)"

Code Code下面向API发送请求。

            disposable = apiServices.getVehicle(token)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(
                    { result ->


                        res_message = "${result.vehicletypes} "
                        Log.d("Type==", res_message)
                    },
                    { error ->
                        res_message = "${error.message}"
                        // validateToken()
                    }
            )

模型类

  data class Vehicles(val success: Boolean, val vehicletypes: List<VehicleType>, val message: String)
  data class VehicleType(val _id: String, val vehicleType: String, val __v: String)

我想在 vehicleListArray

下面的Arralist VehicleType 列表中获取此值

   private var vehicleListArray: ArrayList<Model.VehicleType>? = null

我们如何才能实现这一目标。 提前致谢。

Answer 1

假设您要解析的内容是来自服务的响应，该服务能够向您发送列表的适当格式（例如Json）而不是 Retrofit可以轻松处理解析列表。

在apiService定义中：

$latestDeploymentBlob = Get-AzureStorageBlob -Blob app.version -Container $container -Context $blobContext 
$latestDeployment = $latestDeploymentBlob.ICloudBlob.DownloadText()

如果你还没有：

fun getPeople(token: Whatever): Observable<List<VehicleType>>

Answer 2

我得到了解决方案，我必须处理Respose，如下面的代码片段。

private fun getVehicleType() { 
    disposable?.add(apiServices.getVehicle(token)
            .observeOn(AndroidSchedulers.mainThread())
            .subscribeOn(Schedulers.io())
            .subscribe(this::handleResponse, this::handleError))
}

private fun handleResponse(vehicles: Model.Vehicles) {
    VehiclesArrayList = ArrayList(vehicles.vehicletypes)
    Log.d("type==","n--"+VehiclesArrayList )
    mAdapter = DataAdapter(VehiclesArrayList !!, this)
    v_android_list.adapter = mAdapter
}

private fun handleError(error: Throwable) {
    Log.d("type", error.localizedMessage)
    Toast.makeText(context, "Error ${error.localizedMessage}", Toast.LENGTH_SHORT).show()
}
