我正在制作巴士预订应用程序。我为座位预订创建了几个布局。每个布局都与几乎相同的代码完美配合。但只有1个布局有问题。每个布局都有下层和上层。我用Radio Buttons切换上下甲板的视图。但是，当我点击上层甲板时，它没有显示上层甲板。

仅添加了与Upper Deck相关的代码。拆下下甲板适配器。当我点击Lower时，下层甲板工作正常。但问题只在于上层甲板。
答案 0 :(得分：1)
要回答这个问题非常困难，因为您的代码看起来有些令人困惑，您需要删除一些业务逻辑，只需包含影响手头问题的代码。
我强烈建议您阅读一本名为Clean Code by Robert C. Martin的书，以提高您的编码能力。对于Android，我建议您查看this page。通过清理代码并使其更加模块化和有序，您将能够更好地自行调试和解决此问题。
