Java 微调器项目取决于其他微调器的选定项目

我有两个自定义微调器，从第一个微调器的选定项，我必须修改第二个微调器的可用项。例如：如果我在第一个微调器中选择值“Android”，那么在第二个微调器中，我希望看到Android版本的列表。如果我选择“Apple”，我希望看到iOS版本。等等，适用于许多其他操作系统。如果需要，我还可以选择其中的两个或三个，在第二个微调器中，我希望看到在第一个微调器中选择的每个操作系统的所有操作系统版本

到现在为止没问题

问题在于，自定义微调器同时具有TextView和复选框。我想这就是我的麻烦所在。 结果是，我可以选中/取消选中tha SO项目，但在第二个微调器中，我看不到任何内容

当我在第一个微调器中取消选中某个操作系统时，我还没有实现删除操作系统版本的机制，但我认为我可以通过removeAll（）来完成

我在下面附上代码

（请原谅我的英语很差……我也在努力提高：’） 还有，OT，你能给我推荐一本适合初学者的好书吗谢谢谢谢大家。）
