Android5.0 press the power key to shut down directly without the confirmation dialog box

If you press the power key to shut down Android5.0, the dialog box does not pop up, but after you click the Shutdown option, you should pop up a confirmation dialog box to prompt the user whether the shutdown mode is actually enabled.

First, open the flag of the dialog box at the frameworks layer.

       @Override        public void onPress() {            final boolean quickbootEnabled = Settings.System.getInt(                    mContext.getContentResolver(), "enable_quickboot", 0) == 1;            // go to quickboot mode if enabled            if (quickbootEnabled) {                startQuickBoot();                return;            }            // shutdown by making sure radio and power are handled accordingly.            mWindowManagerFuncs.shutdown(true /* confirm */);//20150423 show the power-off dialog        }

In the source code, the processing of the displayed string is logical. Therefore, if you do not modify the function, the restart dialog box is displayed. Modify as follows:
