In the line ::

android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction().replace(R.id.frame_container, fragment).commit();

I am getting error as::

The method getSupportFragmentManager() is undefined for the type MainActivity 

回答1:

You should extend SherlockFragmentActivity instead of SherlockActivity

回答2:

Use getActivity().getSupportFragmentManager() insted getSupportFragmentManager().

It's work.
