Fragment com.example.myapplication.PersonalCenter must be a public static class to be properly recreated from instance state.

As an AI language model, I can explain that this error message indicates that the "PersonalCenter" fragment class in the "myapplication" package needs to be declared as a public static class. This is required for the fragment to be properly recreated from its saved instance state. When a fragment is recreated, its state is restored from the saved instance state, and if the fragment class is not declared as a public static class, it may not be possible to restore its state correctly, leading to unexpected behavior or crashes. Therefore, it is important to ensure that fragment classes are declared as public static classes to avoid this error.

java.lang.IllegalStateException: Fragment null must be a public static class to be properly recreated from instance state.

这是一个关于 Android Fragment 的异常，它通常发生在 Fragment 类没有被定义为公共静态类的情况下。具体来说，如果在 Fragment 生命周期的某个阶段中，系统尝试从其实例状态中重建 Fragment 实例，并且实例不是公共静态类，则会触发此异常。如果您遇到此问题，您可以将 Fragment 定义为公共静态类或使用 Fragment 参数化构造函数。
