    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;    }}
