android - 我应该如何解析数组中的数组中的Json

Question

我试图解析数组中的数组中的Json，但是没有用。
来源是这样的

    @POST("/storyGet")
fun getStory() : Call<ArrayList<StoryData>>

这是API.kt的

Client.retrofitService.getStory().enqueue(object :
        retrofit2.Callback<ArrayList<StoryData>> {
        override fun onResponse(call: Call<ArrayList<StoryData>>?, response: Response<ArrayList<StoryData>>?) {
            val repo = response!!.body()
            when (response.code()) {
                200 -> {
                    repo!!.indices.forEach {
                        items += StoryDataSubListItem(
                                repo[it][it][it].alreadyWatch,
                                repo[it][it][it].createdAt,
                                repo[it][it][it].imgUrl,
                                repo[it][it][it].storyUUID,
                                repo[it][it][it].userName,
                                repo[it][it][it].userName,
                                repo[it][it][it].userUUID
                            )
                        recyclerView!!.adapter?.notifyDataSetChanged()
                    }
                }
            }
        }

        override fun onFailure(call: Call<ArrayList<StoryData>>?, t: Throwable?) {
        }
    })

这是我的改造数据，

class StoryData : ArrayList<StoryDataSubList>()

这是第一个数组，

class StoryDataSubList : ArrayList<StoryDataSubListItem>()

这是我的第二个数组，

data class StoryDataSubListItem(
val alreadyWatch: List<Any>,
val createdAt: String,
val imgUrl: String,
val storyUUID: String,
val userName: String,
val userProfileImgUrl: String,
val userUUID: String)

这是数据类，数组中的json以数组的格式是

[
[
    {
        "alreadyWatch": [],
        "createdAt": "test",
        "_id": "_id",
        "userUUID": "userUUID2",
        "userName": "userName2",
        "userProfileImgUrl": "false",
        "imgUrl": "imageUrl",
        "storyUUID": "StoryUUID",
        "__v": 0
    }
],
[
    {
        "alreadyWatch": [],
        "createdAt": "test",
        "_id": "_id",
        "userUUID": "userUUID",
        "userName": "TEST NAME",
        "userProfileImgUrl": "false",
        "imgUrl": "imageURL",
        "storyUUID": "StoryUUID",
        "__v": 0
    }
]]

当我看到logcat时，服务器处于正常运行状态
何时需要修复？请帮助并提前感谢您。

您需要按以下方式更改代码，因为响应中包含给定模型数据的另一个列表，

 @POST("/storyGet")
 fun getStory() : Call<List<List<StoryDataSubList>>>

完整代码如下

@POST("/storyGet")
     fun getStory() : Call<List<List<StoryDataSubList>>>

调用Retrofit API的方法以获取如下响应

private fun loadStoryData() {
            val call = netWorkApi.getStory() // replace netWorkApi with your retrofit API sevice
    
            call.enqueue(object : Callback<List<List<StoryDataSubList>>> {
                override fun onResponse(
                    call: Call<List<List<StoryDataSubList>>>,
                    response: Response<List<List<StoryDataSubList>>>
                ) {
                    if (response.isSuccessful) {
                        for (index in response.body()?.indices!!)
                            Log.d("TAG", "${response.body()!!.get(index)}")
    
                    }
                }
    
                override fun onFailure(call: Call<List<List<StoryDataSubList>>>, t: Throwable) {
                    TODO("Not yet implemented")
                }
            });
    
        }
