java如何在Android中使用多个带有Tab片段的按钮？

Question

我正在创建一个简单的应用程序。我正在尝试将数据存储在SQLite db中。我没有错。但是，我觉得我把括号和内部类的嵌套搞砸了。我有3个按钮——日期选择器、时间选择器和创建帐户。用户界面运行良好。我检查了db代码（通过创建其他项目），这也可以正常工作。但是，在这个应用程序中，单击create account后，它不会显示消息——“Data successfully saved”（数据成功保存），或者如果我将字段留空，那么它也不会显示消息——“fields Spanking”（字段留空）。所以，我觉得我对这个特定的代码做了一些错误。我正在关注一个在线教程。你能帮我检查并修改代码吗
