frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java

在PHONEwindowmanager.java里 interceptKeyBeforeQueueing（）方法里加上 if (down && ((keyCode == KeyEvent.KEYCODE_HOME)||(keyCode == KeyEvent.KEYCODE_MENU)||(keyCode == KeyEvent.KEYCODE_BACK))){             performHapticFeedbackLw(null, HapticFeedbackConstants.VIRTUAL_KEY, false);         }
