Android Parse.com挂起一对多关系

我需要保存解析中的一对多关系，每个Cathegory必须有几个问题（最多4个），每个问题必须有问答字符串（最多5个字符串）和另外4个图像（尚未实现），我需要它在线更新“on air”。我目前正在测试数据库服务（现在我决定进行解析，但我需要保存Cathegory和Question之间的关系）

这是我的活动代码（片段）：

}愚蠢的错误。请注意这一点

问题类别的正确代码：

 @ParseClassName("Question")
public class Question extends ParseObject {
public static final String TAG = Question.class.getName();

private String question;
private String rightAnswer;
private String wrongAnswer1;
private String wrongAnswer2;
private String wrongAnswer3;

public Question(){
    //need for Parse
}

public Question(String question, String rightAnswer, String wrongAnswer1, String wrongAnswer2, String wrongAnswer3) {
    super();
    super.put("question", question);
    super.put("rightAnswer", rightAnswer);
    super.put("wrongAnswer1", wrongAnswer1);
    super.put("wrongAnswer2", wrongAnswer2);
    super.put("wrongAnswer3", wrongAnswer3);
    this.question = question;
