Gson解析多元數組

Gson解析多元數組

1、多元數組：

// 三維數組的字元串：
{
    "dept": "[[[120.835572525992,31.287890782283995],[120.83580901430696,31.290597379359326]]]"
}
           

2、Gson解析(TypeToken)：

val jsonArrayStr =  "[[[120.835572525992,31.287890782283995],[120.83580901430696,31.290597379359326]]]"
val gson = Gson()
val type = object :  TypeToken<MutableList<MutableList<MutableList<Double>>>>() {}.type
val resultList: MutableList<MutableList<MutableList<Double>>> =  gson.fromJson(jsonArrayStr , type)

// val jsonArray: JsonArray = JsonParser().parse(jsonArrayStr).asJsonArray
// val resultList: MutableList<MutableList<MutableList<Double>>> =  gson.fromJson(jsonArray , type)
