在文件

frameworks/policies/base/phone/com/android/internal/policy/impl/PhoneWindowManager.java  

中加入

import com.android.internal.app.ShutdownThread; 

在

Runnable mPowerLongPress = new Runnable() {<br /> public void run() {<br /> mShouldTurnOffOnKeyUp = false;<br /> performHapticFeedbackLw(null, HapticFeedbackConstants.LONG_PRESS, false);<br /> sendCloseSystemWindows(SYSTEM_DIALOG_REASON_GLOBAL_ACTIONS);<br /> //showGlobalActionsDialog(); //注释掉<br /> ShutdownThread.shutdown(mContext, false); //添加<br /> }<br /> };  

长按power按键就可以直接关机了
