我想访问这个JSON中的flower_id id的值。我想通过gson或JSONObject来访问它。下面是我的类：

class Json2(val result: Result2) {
}
class Result2(val status:String, val featured_items: Array<FeaturedItems> , val trending_items:Array<TrendingItems> ) {
}
class FeaturedItems(val pic:String, val price:String, val item_name:String, val shop_name:String, val flower_id:String) {
}
class TrendingItems(val pic:String,val price:String, val item_name:String, val shop_name:String, val flower_id:String) {
}

下面是我在AsyncHttpResponseHandler（）的成功部分中编写的内容：

var jsonInfo2 = mutableListOf<FeaturedItems>()
    var jsonInfo3 = mutableListOf<TrendingItems>()

                override fun onSuccess(statusCode: Int, headers: Array<out Header>?, responseBody: ByteArray?) {

                    if (responseBody != null) { val charset2 = Charsets.UTF_8

                        val json2 = String(responseBody, charset2)
                        val gson2 = Gson().newBuilder().serializeNulls().create()

                        val homescreenresult = gson2.fromJson<Json2>(json2, genericType<Json2>())

                        jsonInfo2.addAll(homescreenresult.result.featured_items)

                        jsonInfo3.addAll(homescreenresult.result.trending_items)

这是我需要从中访问flower_id的JSON。

正如您所看到的，trending和featured项目都有flower_id。我希望访问这两个类的数组中的所有flower id，并在单击这两个项目中的任何一个时相应地使用它们。
