实现效果如下

代码分析

找到关机相关内容 GlobalActionsLayout.java ->GlobalActionsDialogLite.java->关机的实际操作位置：ShutDownAction

@VisibleForTestingfinal class ShutDownAction extends SinglePressAction implements LongPressAction {ShutDownAction() {super(R.drawable.ic_lock_power_off,R.string.global_action_power_off);}@Overridepublic boolean onLongPress() {mUiEventLogger.log(GlobalActionsEvent.GA_SHUTDOWN_LONG_PRESS);if (!mUserManager.hasUserRestriction(UserManager.DISALLOW_SAFE_BOOT)) {//   mWindowManagerFuncs.reboot(true);return true;}return false;}@Overridepublic boolean showDuringKeyguard() {return true;}@Overridepublic boolean showBeforeProvisioning() {return true;}@Overridepublic void onPress() {mUiEventLogger.log(GlobalActionsEvent.GA_SHUTDOWN_PRESS);// shutdown by making sure radio and power are handled accordingly.mWindowManagerFuncs.shutdown();}}

往里层追代码，如下：

• onLongPress()-》 mWindowManagerFuncs.reboot(true); 暂不分析，安全模式逻辑去了
• onPress()->mWindowManagerFuncs.shutdown()->
  GlobalActionsComponent shutdown() ->Service shutdown 关机流程
  ->StatusBarManagerService.java -> reboot方法

retoot 相关源码如下：

 /*** Allows the status bar to reboot the device.*/@Overridepublic void reboot(boolean safeMode
