Answer 1

你真的应该研究一下如何在 android 中解析 JsonObject / JsonArray。

请将您的代码也包含在您尝试过的代码中，因为人们在这里帮助解决不进行编码的错误/问题。

这是您可以从中解析 json 的代码

JSONObject jsonObject = new JSONObject();
JSONObject dataObject = jsonObject.getJSONObject("data");
JSONArray imagesArray = dataObject.getJSONArray("images");
ArrayList<String> listOfImagesUrl = new ArrayList<>();
for(int i = 0; i < imagesArray.length(); i++)
{
     listOfImagesUrl.add(imagesArray.getString(i)); // listOfImages
}

// 选项值代码

JSONArray optionsArray = dataObject.getJSONArray("options");
for(int i = 0; i < optionsArray.length(); i++)
{
   JSONObject option = optionsArray.getJSONObject(i);
   JSONArray optionsValueArray = option.getJSONArray("option_value");
   for(int j = 0 ; j < optionsValueArray.length(); j++)
   {
      JSONObject optionValueObject = optionsValueArray.getJSONObject(j);
      String image = optionValueObject.getString("image");
      String price = optionValueObject.getString("price");
      String price_prefix = optionValueObject.getString("price_prefix");
      //same like this
   }
}
