Codenameone 中的放大和缩小过渡

Question

受原生 Android 窗体过渡 zoomOut 和 iOS 应用启动缩放效果的启发，两者都非常酷...

如何在 Codenameone 中实现窗体、对话框和容器的放大或缩小转换？

我希望过渡具有如下所示的缩放动画：

可能最接近某些 Android 效果的是形式之间的 Morph 过渡，它允许组件成长为下一个形式 http://www.codenameone.com/blog/mighty-morphing-components.html

如果您想要更接近上述代码的东西，您可以将组件放在正确的位置并使其变小，然后使用 animateLayout() 使其生长到位。

过去，我们有一个 FlyIn 过渡，它完全映射到这个，但它使用旧的 3D 代码。我认为使用类似于 FlipTransition.

的仿射变换和缩放来实现应该是微不足道的
