    The error means that there is no getSharedPreferences method in View class, because getSharedPreferences is a method of Context class. In order to access getSharedPreferences method inside View class you need to provide it with an instance of Context class. Something like:

    //Instance of Context 
    Context pref;
    
    SharedPreferences sharedPref = pref.getSharedPreferences(PREFRENCES_NAME,0);
    

    Note: Context pref & String PREFRENCES_NAME should not be null;

    Change this code :

    SharedPreferences pref = getSharedPreferences(PREFRENCES_NAME,0);
    

    To :

    SharedPreferences pref = getActivity().getSharedPreferences(PREFRENCES_NAME,0);
    

    Remember you cant call getSharedPreferences method directly from Fragment, because it belongs to the Activity class. Hence, you just need to call getActivity.
