平时用到最多的就是StackLayout Grid RelativeLayout这种,之前看AbsoluteLayout介绍就是,直接写死控件的x y width heght的这种模式,感觉没啥用,但是发现在特定的环境下,这个布局还是很有用的
AbsoluteLayout has the potential to perform layouts without a single measure call. This makes it very powerful for performance. If AbsoluteLayout cannot be used, consider RelativeLayout. If using RelativeLayout, passing Constraints directly will be considerably faster than using the expression API. That is because the expression API uses JIT, and on iOS the tree has to be interpreted, which is slower. The expression API is suitable for page layouts where it only required on initial layout and rotation, but in ListView, where it's run constantly during scrolling, it hurts performance.
根据上面的这个简介,AbsoluteLayout的性能是优于RelativeLayout的,官方对于性能要求较高的,推荐使用这个布局,不知道对于Grid的性能相比怎么样
