问题
I want a search box which sits on top of the layout like this:
http://www.google.com/design/spec/patterns/search.html#search-in-app-search
I do not know whether I have to build it myself from scratch using text boxes, white frames etc., or there is already a built-in widget or an open source work.
Actually designing everything from scratch does not seem to me right. Because by doing so I would have a incompatible view or user experience in future android APIs.
What are the options available and what is the most adopted approach?
