Android Studio - 运行项目时计算无效

时间：2013-11-11 10:36:30

标签： java android

我之前发过一个问题，但没有得到任何回复。

只是一点背景知识，我在Android Studio中使用“带有viewpager的操作栏选项卡”作为导航创建了一个应用程序。运行应用程序时，所有页面都加载，我可以滚动并打开，没有任何问题。但由于某种原因，在运行项目时，calculate.jave（我在下面包含）不会加载/执行/工作。但是，当我只运行我的计算页面时，它可以正常运行并进行计算。

我真的希望有人可以提供帮助。 ：）

请让我知道您希望我包含哪些内容，以便您进一步协助我？

calculate.java（计算值已经改变，所以请忽略数字:)）
