推荐答案
在＆lt;包括/>将只包含XML内容的基础xml文件，就好像整个事情只是一个大的文件。这是一个不错的方式来分享不同的布局之间的布局部分。
The < include /> will just include the xml contents in your base xml file as if the whole thing was just a single big file. It's a nice way to share layout parts between different layouts.
的＆lt; ViewStub />是一个有点不同，因为它不直接引用，并只会加载当你真正使用它/需要它，也就是说，当你设定的能见度可见 （实际上可见）或看不见（仍然不可见，但其大小不是0了）。这是一个很好的优化，因为你可以有吨的小型观点或标题的任何地方一个复杂的布局，仍然有你的活动加载非常快。一旦你使用这些视图之一，它会被加载。
The < ViewStub /> is a bit different because it is not directly included, and will be loaded only when you actually use it/need it, ie, when you set its visibility to VISIBLE (actually visible) or INVISIBLE (still not visible, but its size isn't 0 anymore). This a nice optimization because you could have a complex layout with tons of small views or headers anywhere, and still have your Activity load up really fast. Once you use one of those views, it'll be loaded.
