Cocos2d-x 3.x android平台菜单返回键监听

最近忙完了手里的项目，马上就要接着做大的项目了，抽空学习看看3.2的引擎，自己写几个小游戏试试，留下一些开发经验，以备后用

android平台菜单返回键监听

.h

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

.cpp

//按键控制（检测onkeyreleased有反应）
auto listener = EventListenerKeyboard::create();
listener->onkeyreleased = CC_CALLBACK_2(MenuLayer::onkeyreleased,this);
_eventdispatcher->addEventListenerWithSceneGraPHPriority(listener,this);
void MenuLayer::onkeyreleased(EventKeyboard::KeyCode keyCode,Event* event)
{
    switch(keyCode)
    {
        //监听返回键
        case EventKeyboard::KeyCode::KEY_ESCAPE:
             Director::getInstance()->end();
 
            break;
 
        //监听menu键
        case EventKeyboard::KeyCode::KEY_MENU:
 
            break;
    }
}
