我以下列形式hava json:
"result":[
{"question":"3", "answer":"Doe"},
{"question":"5", "answer":"Smith"},
{"question":"8","answer":"Jones"}
]
和Java类 - >
public class UserResponses {
private Integer question;
private String answer;
//getters and setters
}
如何将json解析为UserResponses列表? 例如,使用GSON?
答案 0 :(得分:0)
JSONObject data = new JSONObject("your_json_data_here");
JSONArray questionArray = data.getJSONArray("result");
//Create an array of questions to store the data
UserResponse[] responsess = new UserResponse[questionArray.length()];
//Step through the array of JSONObjects and convert them to your Java class
Gson gson = new Gson();
for(int i = 0; i < questionArray.length(); i++){
responses[i] = gson.fromJson(
questionArray.getJSONObject(i).toString(), UserResponse.class);
}
这是使用gson解析数据的简单方法。如果你想在没有gson的情况下这样做,你只需要使用questionArray.getJSONObject(i).getString("question")
和questionArray.getJSONObject(i).getString("answer")
的UserResponse类的getter和setter。

如何将json解析为UserResponses列表?例如,使用GSON?
鉴于包含json的“json”变量rappresenting your_kind列表,我将按照以下方式执行(使用反射):
Type type = new TypeToken&gt;(){}。getType();
列出yourList = Gson()。fromJSON(json,type);
