“extends Fragment” Support getSupportActionbar() AppCompat v7 lib????

Standard

– AppCompat/ActionBarCompat in v7 support library.

if extends with “Fragment” not with “ActionBarActivity” then

After Fragment.onActivityCreated() you’ll have a valid activity accessible through getActivity().

You’ll need to cast it to an ActionBarActivity then make the call to getSupportActionBar().

example:

ActionBar actionbar=((ActionBarActivity)getActivity()).getSupportActionBar();

actionbar..setTitle(“title”);

……… hide,subtitle and all work  with extends Fragment.
