android - Android Layout层级的效率

Question

具有复杂的布局层次结构是否(以及以何种方式)影响性能？

它以何种方式影响具有深层嵌套布局的应用程序(例如，RealitiveLayout 包含许多 LinearLayouts，每个 LinearLayouts 包含....)

Answer 1

它有一个作用，规则越简单越好。

Every view — or worse, every layout manager — that you add to your application comes at a cost: initialization, layout and drawing become slower. The layout pass can be especially expensive when you nest several LinearLayout that use the weight parameter, which requires the child to be measured twice.
