我希望你帮助我在我的应用程序中获得这个问题而不重复。在此先感谢：）
答案 0 :(得分：0)
创建随机整数列表：
parseXmlCount = ... // number of questions in XML
List<Integer> indexList = new ArrayList<Integer>();
for (int i = 0; i < parseXmlCount; i++) {
indexList.add(new Integer(i));
}
Collections.shuffle(indexList); // randomize
现在只需通过indexList进行互动即可获得非重复的随机索引
