Difference between <include> and <ViewStub> in android

What are the differences between <\include> tag and <\ViewStub> tag and which one is preferrable while designing the layout.

Thanks,
venu

Answer

According to http://www.edumobile.org/android/viewstub-example-and-use-in-android/:

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.

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.
