使用fragmenttabhost后，子fragment怎么获取ID？怎么用getSharedPreferences

public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View parentView = inflater.inflate(R.layout.fragment1, container, false);
                
        SharedPreferences pre = getActivity().getSharedPeferences(CFG,0);
               //getSharedPeferences("myinfo",Context.MODE_PRIVATE);
        
        return parentView;
        
    }
