提前谢谢。请重新格式化您的问题，您没有正确缩进。您可以简单地告诉我有什么问题。如何解决该问题。。请给我一些提示…@GrayCygnussee“}”挂在外面？…你应该缩进（每层4个空格）正确的代码，我看到你在每行上漏掉了4个空格，所以是在同一个级别上。我已经重新格式化了问题。你们能帮我吗？@GrayCygnusThanks请先重新格式化你的问题，你没有正确缩进。可以简单地告诉我有什么问题。如何解决这个问题。请给我一些提示…@GrayCygnussee that“}“出去玩？”？。。。你应该正确缩进（每级4个空格）你的代码，我发现你每行都漏掉了4个空格，所以这是在同一个级别我已经重新格式化了问题..你们能帮我吗..@graycygnus是的..我想创建这样的代码。。现在，我可以在新活动中提示设置单选按钮的值。请检查我的问题，我已经在@PayalWell添加了一个空指针异常部分，请参考此链接：-ya，这是通过单选按钮的一种方式。如果我想把单选按钮传递给以前的活动，如果把StutyQuast1作为第一个活动，那么StutyQuase2.java作为第二个。这是将单选按钮传递给下一个活动的一种方式。如果我想把单选按钮传递给以前的活动，如果把StutyQuasd1作为第一个活动，那么将StutyQuase2.java作为第二个活动。从surveyquestion2，我希望它传递到surveyquestion1的选定值@Payalyes这是真的..我想创建这样的代码。。现在，我可以在新活动中提示设置单选按钮的值。请检查我的问题，我已经在@PayalWell添加了一个空指针异常部分，请参考此链接：-ya，这是通过单选按钮的一种方式。如果我想把单选按钮传递给以前的活动，如果把StutyQuast1作为第一个活动，那么StutyQuase2.java作为第二个。这是将单选按钮传递给下一个活动的一种方式。如果我想把单选按钮传递给以前的活动，如果把StutyQuasd1作为第一个活动，那么将StutyQuase2.java作为第二个活动。从surveyquestion2，我希望它传递到surveyquestion1的选定值@帕亚尔
