其中为了嵌套布局是最有效的安卓 [英] Which order of nested layouts is most efficient in Android
问题描述
我不认为我真的永远比约三个层次值得布局（<$ C C $> RelativeLayout的，的LinearLayout ，的FrameLayout ）的Android系统。我没有想过列表中的项目还使用自定义布局的ListView ，但只是正常布局的活动。
I don't think I have really ever nested more than about three levels worth of Layouts (RelativeLayout, LinearLayout, FrameLayout) in Android. I am not thinking about list items which also use a custom layout for ListView but just normal layouts for an activity.
要的一点，虽然，我是聊天约嵌套布局另一个开发有一定的布局，我们在讨论，他似乎认为，即使是一些嵌套布局真的放缓的表现。我想有一定的道理，但不能是那么多。
To the point though, I was chatting with another developer about nesting layouts for a certain layout we were discussing and he seemed to think that even a few nested layouts really slowed down performance. I figured there is some truth but it cant be that much.

Does anyone have a more expert approach to this? Any input? Opinion?
