implementing search in the header so as to function in all the screens

I am a newbie to android and apologise if my question is silly. I looked through the net and did not find any proper solution for this.

I want to implement a search function where my edittext is in the header and I want to implement this search function in all the screens with the same functionality. The functionality here is typeahead.

It will be great if I can get some reference to some reading materials which would help me开发者_StackOverflow in this or a short hint in any way that can be helpful.

Thanks for your help. I tried it but could not get it working as my activity is not launched. I invested quite a bit of time but did not get through. Is it possible to get a dummy code or prototype with one screen somewhere online so that I can build up on that?

If you want to use the standard Android search interface (which pops up with an edittext in most apps), you'll want to check out search on the Android Developers website. It's a really useful article and worth reading through. If you want the functionality in all the activities, do as it says and put the android.app.default_searchable meta-data tag in the <application> element, not just each <activity> one.
