Answer 1

我面临同样的问题，几乎我花了半天时间，最后解决方案是关闭 eclipse 和 PC/笔记本电脑，重新启动它并运行应用程序。一切都运行良好。

Answer 2

您抛出了ArrayIndexOutOfBoundsException。检查 Shout.java 中 1923 年执行的代码以进行数组访问。如果您尝试按索引读取大于数组大小（1）的元素，则会引发异常。例如，如果出现以下情况，则会抛出该异常：

String [] strings = new String[0];
strings[0];// exception thrown!

尝试项目 ->清理然后运行......我已经这样解决了......
