我一直在调试这个问题，但我找不到将布尔值设置为字符串或其他什么的位置。如果需要，我可以展示更多内容，但如果您在我的堆栈跟踪中看到任何内容，请告诉我。

我的堆栈跟踪：

检查线路：

Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean

看起来，您将值保存为共享首选项中的字符串并将其作为布尔值读回，这会导致此异常。

检查哪种值 -String/Boolean 适合您并保存和读取类似类型的值以解决此问题。

就像，当您将字符串值保存在 Shared Prefrences 中时，将其作为字符串读回。或者，如果您需要将值读取为 Boolean ，请将其另存为 Boolean 。

如果您保存了具有要存储的密钥等的“共享首选项”，这些密钥使用“字符串”值，那么稍后您在需求更改后为“CheckBoxPreference”使用相同的密钥。

在这种情况下，您必须从手机中为您的应用删除 sharedPreferences。因为之前存储的 value 是 String，现在 key 用于存储 Boolean。

您必须在 Shared Prefs 中传递一个值并将其设置为布尔类型，但将该值作为字符串传递。我的意思是你必须像这样传递真或假——“真”，你需要像这样传递它——真的。
