我这样做是为了捕捉Home和Back按钮按下Android设备上的事件:

覆盖这样的void Layer::onKeyReleased(EventKeyboard::KeyCode keyCode, Event* event)功能:

void MyLayer::onKeyReleased(EventKeyboard::KeyCode keyCode, Event* event)
{
    if (keyCode == EventKeyboard::KeyCode::KEY_BACKSPACE /*KeyboardEvent::KeyCode::Menu(KEY_BACKSPACE)*/)
    {
         CCLOG("You pressed back button");
         Director::getInstance()->end();
         exit(0);
    } 
    else if (keyCode == EventKeyboard::KeyCode::KEY_HOME)
    {
         CCLOG("You pressed home button");
         // pause the game
    }
}

也有称之为setKeypadEnabled(true);的init功能MyLayer.Backspace按钮关闭Windows上的游戏,但Home按钮没有反应.同样在Android上,当我按Home或Back时没有任何反应.如何在cocos2d-x 3.1上运行？
