Android - 字符串无法转换布尔值SharedPreferences

问题描述 投票：1回答：3

我已经调试了这个问题一段时间，我找不到我将布尔值设置为字符串或其他什么。如果需要，我可以显示更多，但如果您在我的堆栈跟踪中看到任何内容，请告诉我。

检查线：

Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean
08-13 21:25:31.910: E/AndroidRuntime(10583):    at android.app.SharedPreferencesImpl.getBoolean(SharedPreferencesImpl.java:242)

看起来，您正在将值保存为共享首选项中的String并将其作为布尔值读回，这会导致此异常。

检查什么类型的值-String / Boolean适合您，并保存并读取相似类型的值来解决此问题。

就像在Sharedpreferences中保存String值一样，将其作为String读回。或者，如果需要将值读取为布尔值，请将其另存为布尔值。

如果你已经保存了“存储密钥”的“共享首选项”，使用“字符串”值，那么稍后在需求更改后使用相同的密钥进行“CheckBoxPreference”。

在这种情况下，您必须从应用程序的手机中删除sharedPreferences。因为以前存储的值是String，现在key用于存储Boolean。

您必须在共享首选项中传递值并将其作为布尔类型传递，但将值作为String传递。我的意思是你必须像这样传递真或假 - “真实”，你需要像这样传递 - 真实。
