Fragment ist Gebrauch So ...

public class YourFragment extends Fragment { 

private View rootview; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    rootview = inflater.inflate(R.layout.activity_main, container, false); 

return rootview; 
} 
}
