Android 5.1长按电源键添加重启功能

原址:http://blog.csdn.net/zhoumushui

现在长按Power键只有一个关机键，需要添加一个重启，以下是我的添加步骤：

1.在frameworks/base/core/res/res/values/config.xml里添加重启：

 "false" name="config_globalActionsList">
     power
     reboot
     bugreport
     users

2.添加中英文的重启string：

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

frameworks/base/core/res/res/values-zh-rCN/strings.xml

3.修改GlobalActions：

frameworks/base/policy/src/com/Android/internal/policy/impl/GlobalActions.Java

可以看到onPress()中是对重启的实现：

 Intent intent = new Intent(Intent.ACTION_REBOOT);
 intent.putExtra("nowait", 1);
 intent.putExtra("interval", 1);
 intent.putExtra("window", 0);
 mContext.sendBroadcast(intent);

Done！
