android - 我应该在 Android Jetpack Compose 中使用 ConstraintLayout 以获得更好的性能吗？

Question

在 Jetpack 组合之前 ConstraintLayout是构建复杂布局的推荐方式，因为它允许扁平化 UI 层次结构。见 Manage complexity: layouts matter文档部分。

The most common case in which layout takes an especially long time is when hierarchies of View objects are nested within one another. Each nested layout object adds cost to the layout stage. The flatter your hierarchy, the less time that it takes for the layout stage to complete.

在 Compose 世界中仍然如此吗？

Answer 1

在 Compose 中并非如此。如果 ConstraintLayout 可以帮助您实现布局但不是因为性能问题，请使用它。见 Compose ConstraintLayout documentation :

Note: In the View system, ConstraintLayout was the recommended way to create large and complex layouts, as a flat view hierarchy was better for performance than nested views are. However, this is not a concern in Compose, which is able to efficiently handle deep layout hierarchies.
