Android7.1 动态显示和隐藏导航栏和状态栏 广播_android 设置状态栏覆盖在布局之上,并动态的显示和隐藏状态栏

由于公司项目需要动态显示和隐藏导航栏和状态栏，所以就需要从底层代码加入广播命令，下面是实际操作过程。


一、文件路径	
       /frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java
	   在源码中增加如下代码，保存后重新编译，然后用adb shell am -a "..........."命令测试，
	   例如：adb shell am -a "lyzk.intent.systemui.hidenavigation"
