面对raspberry-pi-android的改型错误，无法找出发生了什么异常，我正在使用raspberry-pi（android 8.0）改型，试图找出在移动设备中什么样的问题和相同的代码起作用。我在oncreate（）中调用getlogin（）函数，但不返回响应。

private fun getLogin() {

  val userid = username.text.toString()
        val pwd = password.text.toString()
        Global.pswd = pwd

        try{

        val gson = GsonBuilder().registerTypeAdapter(LoginResponse::class.java , 
       LoginResponse.DataStateDeserializer()).create()

        val retrofit : Retrofit =  Retrofit.Builder()
                .baseUrl(Global.Main_Url)
                .addConverterFactory(GsonConverterFactory.create(gson))
                .build()

        val apiInterface = retrofit.create(ApiInterface::class.java)

        val call: retrofit2.Call<LoginResponse> = apiInterface.getLogin(
                Responses.LoginResponse(Global.HmiSrNo , "1" ,"1" , "IDS")
        )
        call.enqueue(object : Callback<LoginResponse> {
            override fun onFailure(call: retrofit2.Call<LoginResponse>?, t: Throwable?) {

                //--  snackbar to dispaly error  --//
                val snackbar =
                        Snackbar.make(item, t!!.message!!, Snackbar.LENGTH_LONG)
                                .setAction("Retry") {
                                    getLogin()
                                }
                snackbar.setActionTextColor(Color.YELLOW)
                snackbar.show()
            }

            override fun onResponse(
                    call: retrofit2.Call<LoginResponse>?,
                    response: retrofit2.Response<LoginResponse>?
            ) {

                if (response!!.isSuccessful) {
                    val list = response.body()
                    val status = list!!.status
                    if (status == "success") {

                        Global.userid   = list.UserID
                        Global.userName = list.UserName

                        val intent = Intent(applicationContext, BalanceCalibration::class.java)
                        startActivity(intent)
                        progressDialog.dismiss()
                    } else {
                        val snackbar =
                                Snackbar.make(item, list.result.toString(), 
                        Snackbar.LENGTH_INDEFINITE)
                        snackbar.setAction("OK"){
                            snackbar.dismiss()
                        }
                        snackbar.setActionTextColor(Color.YELLOW)
                        snackbar.show()
                    }
                }
            }

        })
        }catch (e:Exception){
            e.printStackTrace()
        }

}

我的模特课：

class LoginResponse {

        @SerializedName("status")
        lateinit var status:String

        @SerializedName("message")
        lateinit var message : String

        @SerializedName("result")
        lateinit var result:Any

        lateinit var UserID: String

        lateinit var UserName:String

        lateinit var realPassword: String

        class DataStateDeserializer : JsonDeserializer<LoginResponse>
        {
            override fun deserialize(
                    json: JsonElement?,
                    typeOfT: Type?,
                    context: JsonDeserializationContext?
            ): LoginResponse {
                val loginResponse : LoginResponse = Gson().fromJson(json, LoginResponse::class.java)
                val jsonObject = json!!.asJsonObject
                if(jsonObject.has("result"))
                {
                    val element = jsonObject.get("result")
                    if(element != null && !element.isJsonNull)
                    {
                        if(element.isJsonPrimitive){
                            loginResponse.result = element.asString
                        }
                        else{
                            loginResponse.UserID = element.asJsonObject.get("UserID").asString
                            loginResponse.UserName = element.asJsonObject.get("UserName").asString
                        }
                    }
                }

                return loginResponse
            }

        }
    }

我的界面：

interface ApiInterface {

            @POST("/API/Login/loginMain")
            fun getLogin(@Body body: Responses.LoginResponse): Call<LoginResponse>
        }
