我正在建立一个测验。当用户没有生命时，会出现一个带有“重启”的按钮，我希望游戏重置，我创建了一个名为finishButton的IBaction按钮，它将所有标签重新启动到其初始值，但我无法使函数randomQuestion为重新开始，或者使字符串randomQuestionArray重置，或者只是其他任何东西，以便我的测验将从零开始。我尝试了所有，我需要你们的帮助，真的很感激。
以下是代码：

答案 0 :(得分：1)
在randomQuestionArray，您需要重新初始化randomQuestionArray = [1, 2, 3, 4]
：
Intent resumeIntent = new Intent (this, Class.forName(getPackageName() + resumeName);
startActivity(resumeIntent);
