Gson解析Json

Question

我如何使用GSON解析这个json？

[
 [
   456239452,180279471,"fsdgdfgdfg","T",
   "M",244,0,0,"",0,82,"","[]","fgfdgdfg",10
 ],
 [
   456239451,180279471,"9wnntiu5vu9mBeDiBej4swfcztjOS4nJe",
   "R","s",253,0,0,"",0,82,"","[]","cf46","g",14
 ]
]

我的代码：

data class Data(val list: List<List<String>>)

Gson().fromJson(json, Data::class.java).let {
    it.list.forEach {
        it.forEach {
            println(it)
        }
    }
}

这似乎是您唯一能做的事情--将其解析为List<List<Any>>，然后通过索引访问元素。

为了达到这个目的，你应该做如下的事情

import java.lang.reflect.Type
import com.google.gson.reflect.TypeToken

Type listType = object: TypeToken<List<List<Any>>>(){}.type
List<List<Any>> list = Gson().fromJson(jsonArray, listType)
