2dx相对布局和Android非常类似。假设前完成Android它应该是easy入门。

        Size widgetSize = Director::getInstance()->getWinSize();

        Text* alert = Text::create("Layout", "fonts/Marker Felt.ttf", 30 );

        alert->setColor(Color3B(159, 168, 176));

        alert->setPosition(Point(widgetSize.width / 2.0f,

                                 widgetSize.height / 2.0f - alert->getSize().height * 3.075f));

        addChild(alert);

        Layout* layout = Layout::create();

        layout->setSize(Size(widgetSize.width, widgetSize.height));

        //横向排列，这里相似Android里的线性布局

        layout->setLayoutType(LAYOUT_RELATIVE);

        /*以图片为背景*/

        layout->setBackGroundImageScale9Enabled(true);

        layout->setBackGroundImage("green_edit.png");
