How do I get news feeds? Just like News and Weather app

Question

I'm trying to know how to implement the news feed retrieval, just like how it is on the News and Weather app:

In the app (News and Weather), you have the option of writing the name, then the app retrieves the news based upon it. (Menu -> Settings -> News Settings -> Select news topics)

For example, if I say "Android", it'll fetch me news relating to "Android".

Is this based on RSS? How does it work and how can I implement it in my app?

Thanks!

I am saying as i understand:
u want to make news search box* : user type any word and find latest news about written topic:
i think u have to store ur RSS feed in db and then fire query on db and display news...
