how do I resize layout and change percent position child (sprite) of layout or is there any way to change the child position when resizing the parent?

[hoafiaan]

I use layout->setContentSize(Director::getInstance()->getVisibleSize()) and layout->forceDoLayout() but it doesn't working

Your requirements are not clear, but if they are somehow related to automatically adjusting child widget positions on a ui::Layout, then look into Widget::setLayoutParameter. The cpp-tests has examples of layout parameter usage.

I mean with child as sprite in ui::Layout

[rh101]

ax::Sprite does not inherit from ax::Widget, so it doesn't have the same layout capabilities.

There are several ways around this, for example, use ui::ImageView if it's just a static image, or add the sprite as a child of a ax::ui::Widget or ui::Layout, and then that widget will be automatically positioned in the parent layout when it is resized.

You may also be able to sub-class Widget and add Sprite functionality to it, or inherit from both etc. etc..
