添加 5 个自定义保留按键

说明
修改源码

说明

按键自定义

usr/keylayout/xxxx.kl

kernel/include/dt-bindings/input/input.h

frameworks/native/include/input/InputEventLabels.h

frameworks/native/include/android/keycodes.h

frameworks/base/core/java/android/view/KeyEvent.java

frameworks/base/core/res/res/values/attrs.xml

系统层使用自定义按键

PhoneWindowManager.java

应用层使用自定义按键

类方法里覆写 onKey() 即可.
