Android4.2代码位置： \frameworks\base\policy\src\com\android\internal\policy\impl\PhoneWindowManager.java
关键方法： PhoneWindowManager.java -->interceptKeyBeforeQueueing()
case KeyEvent.KEYCODE_POWER: //26

复制代码 -->interceptPowerKeyDown() -->private final Runnable mPowerLongPress = new Runnable() {         case LONG_PRESS_POWER_GLOBAL_ACTIONS:             mPowerKeyHandled = true;             if (!performHapticFeedbackLw(null, HapticFeedbackConstants.LONG_PRESS, false)) {                 performAuditoryFeedbackForAccessibilityIfNeed();             }             sendCloseSystemWindows(SYSTEM_DIALOG_REASON_GLOBAL_ACTIONS);             showGlobalActionsDialog();             break;
