first of all   a Fragment must be inside a FragmentActivity  that s the first rule    a FragmentActivity is quite similar to a standart Activity that you already know  besides having some Fragment oriented methods  second thing about Fragments  is that there is one important method you MUST call  wich is onCreateView  where you inflate your layout  think of it as the setContentLayout  here is an example        Override public View onCreateView LayoutInflater inflater  ViewGroup container  Bundle savedInstanceState        mView         inflater inflate R layout fragment layout  container  false         return mView      and continu your work based on that mView  so to find a View by id  call mView findViewById          for the FragmentActivity part   the xml part  must  have a FrameLayout in order to inflate a fragment in it           lt FrameLayout             android id    id content frame              android layout width  match parent              android layout height  match parent    gt           lt  FrameLayout gt    as for the inflation part  getSupportFragmentManager   beginTransaction   replace R id content frame  new YOUR FRAGMENT   TAG   commit       begin with these  as there is tons of other stuf you must know about fragments and fragment activities  start of by reading something about it  like life cycle  at the android developer site
