Cocos2d-x3.0 捕捉Android的菜单键和返回键

.cpp文件

auto listener = EventListenerKeyboard::create();

	listener->onKeyReleased = CC_CALLBACK_2(HelloWorld::onKeyReleased, this);

	Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, this);

void  HelloWorld::onKeyReleased(EventKeyboard::KeyCode keycode, cocos2d::Event *event){

	switch (keycode){

	case cocos2d::EventKeyboard::KeyCode::KEY_BACKSPACE:

	case cocos2d::EventKeyboard::KeyCode::KEY_BACK:

#if (CC_TARGET_PLATFORM == CC_PLATFORM_WP8) || (CC_TARGET_PLATFORM == CC_PLATFORM_WINRT)

		MessageBox("You pressed the close button. Windows Store Apps do not implement a close button.", "Alert");

		return;

#endif

		Director::getInstance()->end();

#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)

		exit(0);

#endif

		break;

	default:

		break;

	}
}

.h文件

 virtual void onKeyReleased(EventKeyboard::KeyCode keyCode, Event* event);

在此前是不够的，一定注意在.h文件中添加USING_NS_CC;否则会报错。
