onRestoreInstanceState没执行

There could be several reasons why the onRestoreInstanceState method is not being executed. Here are a few possible explanations:

1. The activity may not have been destroyed and recreated. The onRestoreInstanceState method is only called when the activity is being restored after being destroyed, for example, during a configuration change like screen rotation. If the activity has not been destroyed, this method will not be called.

2. The onSaveInstanceState method may not have been called. The onRestoreInstanceState method is called after the onSaveInstanceState method, which is responsible for saving the state of the activity. If the onSaveInstanceState method is not called, the onRestoreInstanceState method will not be executed.

3. The activity may not be properly configured to handle state restoration. Make sure that the activity has the appropriate attributes set in the AndroidManifest.xml file, such as android:configChanges="orientation|screenSize" to indicate that it can handle configuration changes.

4. There may be an error or issue in the implementation of the onRestoreInstanceState method. Double-check your code to ensure that it is correctly implemented and that there are no errors or exceptions preventing the method from being executed.

If none of these explanations apply, it would be helpful to provide more information about your specific code and scenario in order to identify the cause of the issue
