打開文件：frameworksbasepolicysrccomandroidinternalpolicyimplPhoneWindowManager.java 在代碼： private static final int MSG_POWER_LONG_PRESS = 14;下面添加：

private static final int MSG_POWER_SHUT_DOWN=15;

在：

case MSG_POWER_LONG_PRESS: powerLongPress(); break;

下面添加：

case MSG_POWER_SHUT_DOWN:mWindowManagerFuncs.shutdown(false);break;

找到 case KeyEvent.KEYCODE_POWER:注釋掉

/*result &= ~ACTION_PASS_TO_USER; isWakeKey = false; // wake-up will be handled separately if (down) { interceptPowerKeyDown(event, interactive); } else { interceptPowerKeyUp(event, interactive, canceled); } break;*/

再添加：

if(down){if(mPowerManager.isScreenOn()) {Message msg = mHandler.obtainMessage(MSG_POWER_SHUT_DOWN);msg.setAsynchronous(true);mHandler.sendMessageDelayed(msg,ViewConfiguration.get(mContext).getDeviceGlobalActionKeyTimeout());} else {Log.e('GO to Wakeup--------> TTTEEE','keyCode :'+keyCode);wakeUpFromPowerKey(event.getDownTime());}} break;

之后在目錄frameworks/base/policy中mm編譯出android.policy.jar push到system/framework重啟即可
