我想从一个函数调用 volley 请求，该函数将 return arraylist 到其他一些 activity 并且 volley 响应需要转换为模型

Question

我想从 volley 中获取结果，然后解析结果以创建模型 arraylist 和调用 volley 请求的函数应该 return arraylist，该函数从各种其他活动和代码中调用是别人写的，所以我需要想办法在这个 class

中实现同样的目标

这是完整的 class 代码

class Mock @Inject constructor(private val context: Context) {


    val url = Constant.prefix + "get_short_videos.php"

    fun loadMockData(): ArrayList<StoriesDataModel>? {
      //  val mockData = context.resources.openRawResource(R.raw.stories_data)
       // val dataString = mockData.bufferedReader().readText()

        val scope = CoroutineScope(Dispatchers.Main).launch {
            val data = getData()
        }


        Log.e("Rresponse",dataString+"-");
        val gson = Gson()
        val storiesType = object : TypeToken<ArrayList<StoriesDataModel>>() {}.type
        val storiesDataModelList = gson.fromJson<ArrayList<StoriesDataModel>>(dataString, storiesType)




        return storiesDataModelList
    }


    suspend fun getData() = suspendCoroutine<String> { cont ->

        val requestQueue = Volley.newRequestQueue(context)
        val postRequest: StringRequest = object : StringRequest(
            Method.POST, url,
            Response.Listener { response: String? ->

                Log.e("response",response.toString());
                cont.resume(response.toString())
            },
            Response.ErrorListener { error: VolleyError ->
                error.printStackTrace()
                Toast.makeText(context, "Check your internet connection", Toast.LENGTH_SHORT)
                    .show()
            }
        ) {
            override fun getParams(): Map<String, String>? {
                val params: MutableMap<String, String> = HashMap()
                params["mobile"] = context.getSharedPreferences(Constant.prefs, Context.MODE_PRIVATE).getString("mobile","").toString();
                params["length"] = "0";
                return params
            }
        }
        postRequest.retryPolicy =
            DefaultRetryPolicy(
                0,
                DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT
            )
        requestQueue.add(postRequest)


    }
}

我尝试了互联网上提供的各种不同方法，但无法找到一种方法，kotlin 的新手，所以对协程不太了解，感谢任何帮助，提前致谢

我添加的这些 suspendCoroutine 和 CoroutineScope 所以这些可能不应该在这里

能够找到解决问题的方法，如果有人需要这个，这里是答案

class Mock @Inject constructor(private val context: Context) {


    val url = Constant.prefix + "get_short_videos.php"

    private var parentJob = Job()
    private val coroutineContext: CoroutineContext get() = parentJob + Dispatchers.Main
    private val scope = CoroutineScope(coroutineContext)

    suspend fun loadMockData(): ArrayList<StoriesDataModel>? {
      //  val mockData = context.resources.openRawResource(R.raw.stories_data)
       // val dataString = mockData.bufferedReader().readText()

        var dataString = "";
//        val scope = CoroutineScope(Dispatchers.Main).launch {
//            dataString = getData()
//        }
        scope.async(Dispatchers.IO) {
            val success = async { getData() }
            dataString = success.await()

            Log.e("Rresponse2",dataString+"-");
        }.await();

        Log.e("Rresponse",dataString+"-");
        val gson = Gson()
        val storiesType = object : TypeToken<ArrayList<StoriesDataModel>>() {}.type
        val storiesDataModelList = gson.fromJson<ArrayList<StoriesDataModel>>(dataString, storiesType)


        return storiesDataModelList
    }


    suspend fun getData() = suspendCoroutine<String> { cont ->

        val requestQueue = Volley.newRequestQueue(context)
        val postRequest: StringRequest = object : StringRequest(
            Method.POST, url,
            Response.Listener { response: String? ->

                Log.e("response",response.toString());
                cont.resume(response.toString())
            },
            Response.ErrorListener { error: VolleyError ->
                error.printStackTrace()
                Toast.makeText(context, "Check your internet connection", Toast.LENGTH_SHORT)
                    .show()
            }
        ) {
            override fun getParams(): Map<String, String>? {
                val params: MutableMap<String, String> = HashMap()
                params["mobile"] = context.getSharedPreferences(Constant.prefs, Context.MODE_PRIVATE).getString("mobile","").toString();
                params["length"] = "0";
                return params
            }
        }
        postRequest.retryPolicy =
            DefaultRetryPolicy(
                0,
                DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT
            )
        requestQueue.add(postRequest)


    }
}

还需要使函数从调用的主函数挂起

我想从一个函数调用 volley 请求，该函数将 return arraylist 到其他一些 activity 并且 volley 响应需要转换为模型

I want to call a volley request from a function that will return the arraylist to some other activity and volley response needs to converted to model
