问题描述

我要放弃我的Cocos2D-X游戏后退按钮preSS的Android系统。为此，我已经超负荷了 CCLayer :: keyBackClicked 在我的类方法 GameScene ，我也叫 setKeypadEnabled（真）从 GameScene ::初始化。但是， keyBackClicked 方法不会被调用时，pressing后退按钮，我已经检查了 CCLOG 信息。还有什么我需要做的，使这项工作？我搜索了很多关于这个话题，发现上面的解决方案，但它不工作。

I want quit my Cocos2d-x game on back button press in Android. For this I have overloaded the CCLayer::keyBackClicked method in my class GameScene and I have also called setKeypadEnabled(true) from GameScene::init. However, the keyBackClicked method is never called when pressing the back button, I have checked with a CCLog message. What else do I have to do to make this work? I have searched a lot on this topic and found the above solution but it's not working.

下面是我的code

bool GameScene:: init() {
    if(CCLayer::init()) {
        CCLog("Init");
        this->setKeypadEnabled(true);
        return true;
    }
    return false;
}

void GameScene:: keyBackClicked(void) {
    CCLayer::keyBackClicked();
    CCLOG("cclayer key back clicked");
    exit(0);
}

请帮忙。

推荐答案

CCLayer添加代理功能中的OnEnter（）函数调用，您可能需要调用 CCLayer ::的OnEnter 在 GameScene ::的OnEnter（）或也许你需要在其他地方添加。

CCLayer add the delegate function in the onEnter() function call,you may need call CCLayer::onEnter in GameScene::onEnter() or maybe you need add it elsewhere.

CCLayer::onEnter
//
...
    if (m_bKeypadEnabled)
    {
        pDirector->getKeypadDispatcher()->addDelegate(this);
    }
//
...
