如何从列表中获取Arraylist中的Json响应 <Item> 使用RxJava和Kotlin

Question

Facing Problem on getting Response in ArrayList.

I have following Respose on String value

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

Getting below Value on this String

     [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)] 

Retrofit Result is

 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)"

Below Code snippest sending request to API.

            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()
                    }
            )

Model Class

  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)

I want to get this value on Arralist VehicleType List on below vehicleListArray

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

How we can achieve this. Thanks in advance.

Answer 1

Assuming that what you are trying to parse is a response from a service that is able to send you propper format for lists (eg Json) than Retrofit can handle parsing lists with ease.

In your apiService definition:

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

And if you don't have it already:

Retrofit.Builder()
   .addConverterFactory(GsonConverterFactory.create(gson))

I got solution I have to handle Respose as below code snippet.

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()
}
