too much measure

[fanhongwei]

when flexbox parent view align-items is stretch, view visible changed will call too much measure.

This is duplicate of #46. Some measurements could be skipped, but basically if the attributes that are going to be relevant of deciding the size of the view, some views have to measured multiple times.

@thagikura I transformed align-items stretch to Android view match_parent, it is faster.
is there any potential risk？

If setting as match_parent meets your needs, shouldn't be a problem.

The behavior of those twos are different.
alignItems stretch -> The cross size of the views are stretched to the largest cross size in the same flex line.
match_parent -> Fit to the parent size.

@thagikura I know the different between alignitems-stretch and match_parent， there is a bug of flexbox-layout，when parent is align-items stretch and child set width or height，CSS Flex will use child own width or height, but flexbox-layout will use align-items stretch。

Ok, confirmed that there is a difference with the CSS spec with that behavior.
That is different from this issue. Is it possible to file a bug for that?
