android 应用中的问题在洗牌时重复出现
Questions in android app gets repeated when shuffling them
我是整个编码世界的新手。我目前正在为孩子们创建一个学习应用程序，其中一个类别是参加测验。我想打乱所有的问题并且我能够这样做但是我现在面临的问题是问题被重复
这是我用于测验问题的代码activity

我还创建了以下 Questions.class:
public class Question {
private String question;
private int image;
private String optionOne, optionTwo, optionThree, optionFour;
private String correctAnswer;
public Question(String question, int image, String optionOne, String optionTwo, String optionThree, String optionFour, String correctAnswer) {
this.question = question;
this.image = image;
this.optionOne = optionOne;
this.optionTwo = optionTwo;
this.optionThree = optionThree;
this.optionFour = optionFour;
this.correctAnswer = correctAnswer;
}
public String getQuestion() {
return question;
}
public int getImage() {
return image;
}
public String getOptionOne() {
return optionOne;
}
public String getOptionTwo() {
return optionTwo;
}
public String getOptionThree() {
return optionThree;
}
public String getOptionFour() {
return optionFour;
}
public String getCorrectAnswer() {
return correctAnswer;
}
}
如果代码有问题，请接受我的道歉，就像我说的，我对这一切都是新手，而且是自学的。因此，我们将不胜感激。
提前致谢
问题是您在 updateQuestion 中调用随机播放函数。因此它会在每次调用 updateQuestion 方法时更新 questionArray。
解决方案
从 updateQuestion 方法中删除 shuffleQuestions(); 并将其添加到 updateQuestion();[=25= 之前] 在 onCreate 方法中，这样当加载 class 时，洗牌在开始时发生一次。

private String correctAnswer;
public Question(String question, int image, String optionOne, String optionTwo, String optionThree, String optionFour, String correctAnswer) {
this.question = question;
this.image = image;
this.optionOne = optionOne;
this.optionTwo = optionTwo;
this.optionThree = optionThree;
this.optionFour = optionFour;
this.correctAnswer = correctAnswer;
}
public String getQuestion() {
return question;
}
public int getImage() {
return image;
}
public String getOptionOne() {
return optionOne;
}
public String getOptionTwo() {
return optionTwo;
}
public String getOptionThree() {
return optionThree;
}
public String getOptionFour() {
return optionFour;
}
public String getCorrectAnswer() {
return correctAnswer;
}
}
如果代码有问题，请接受我的道歉，就像我说的，我对这一切都是新手，而且是自学的。因此，我们将不胜感激。
提前致谢
问题是您在 updateQuestion 中调用随机播放函数。因此它会在每次调用 updateQuestion 方法时更新 questionArray。
解决方案
从 updateQuestion 方法中删除 shuffleQuestions(); 并将其添加到 updateQuestion();[=25= 之前] 在 onCreate 方法中，这样当加载 class 时，洗牌在开始时发生一次。
