我非常新的Cocos2D ..我在開發Android的使用cocos2d中的應用。在這，Android的cocos2d的添加子節點拋出空指針異常
public class BaseLayer extends CCLayer {
ChildLayer cl = new ChildLayer();
this.addChild(cl); ------------------------------>
}
public class ChildLayer extends CCLayer {
public ChildLayer() {
CCLayer.node();
}
.
.
}
在此，箭頭線拋出空指針例外.. 錯誤日誌低於..

我不知道如何解決這個問題。我不知道爲什麼發生這種情況。由於我沒有太多熟悉的cocos2d ..請幫我解決這個問題。有人請幫助我..
