android - 解析来自凌空的请求

Question

我有一个奇怪的问题，我向服务器发出了一个简单的请求，它响应成功，我解析它没有问题，然后我将从服务器返回的值分配给我的响应模型类，但没有任何东西出现，尽管我找到了它们在日志文件中：（提示：大部分响应是阿拉伯语）

这是我的响应模型类：

    public class QuestionResponse {
        private String lang,questionID,question,choiceOne,choiceTwo,choiceThree,
                type;

        public QuestionResponse(){}

        public QuestionResponse(String lang, String questionID, String question, 
                                String choiceOne, String choiceTwo, String choiceThree, String type) {
            this.lang = lang;
            this.questionID = questionID;
            this.question = question;
            this.choiceOne = choiceOne;
            this.choiceTwo = choiceTwo;
            this.choiceThree = choiceThree;
            this.type = type;
        }

        public String getLang() {
            return lang;
        }

        public void setLang(String lang) {
            this.lang = lang;
        }

        public String getQuestionID() {
            return questionID;
        }

        public void setQuestionID(String questionID) {
            this.questionID = questionID;
        }

        public String getQuestion() {
            return question;
        }

        public void setQuestion(String question) {
            this.question = question;
        }

        public String getChoiceOne() {
            return choiceOne;
        }

        public void setChoiceOne(String choiceOne) {
            this.choiceOne = choiceOne;
        }

        public String getChoiceTwo() {
            return choiceTwo;
        }

        public void setChoiceTwo(String choiceTwo) {
            this.choiceTwo = choiceTwo;
        }

        public String getChoiceThree() {
            return choiceThree;
        }

        public void setChoiceThree(String choiceThree) {
            this.choiceThree = choiceThree;
        }

        public String getType() {
            return type;
        }

        public void setType(String type) {
            this.type = type;
        }
    }

这是我的请求方法：

是的，因为“ques”在设置响应中的值之前返回。

尝试在此方法中设置您的“问题”值

              @Override
                public void onResponse(String response) {
                   //set your values here in the adapter
                   }
