The realization of thought:The Windowmanagerservice loop reads the following key information and distribution forms. Filtering of messages in the Phonewindowmanager.interceptkeybeforequeueing method.Therefore, the implementation is to listen to the current key in the Interceptkeybeforequeueing method before the message is distributed to the volume key, assuming the current state is the lock screen state. And the key is the
