推荐答案

好一些布局，只能通过做嵌套的某些层面上进行。但是，你应该避免过多的嵌套LinearLayouts更重要NEVER巢LinearLayouts配重块。你可以阅读更多一点关于href=\"http://developer.android.com/training/improving-layouts/optimizing-layout.html\" rel=\"nofollow\">官方文档的 。

Well some layouts can only be made by doing some level of nesting. But you should avoid having too many nested LinearLayouts and even more important NEVER nest LinearLayouts with weights. You can read a little more about optimizing layouts in the official docs.

我个人使用的简单的东西LinearLayouts并开始使用的RelativeLayout时的布局变得更加复杂。有没有一个答案，因为它是prefference的问题。

Personally I use LinearLayouts for simple stuff and start using RelativeLayout when the layout gets more complex. There is no one answer as it is a matter of prefference.
