As a note of caution this answer provided by the user above me is correct   SharedPreferences preferences   this getActivity   getSharedPreferences  pref  0     However  if you attempt to get anything in the fragment before onAttach is called getActivity   will return null

getActivity   and onAttach   didnot help me in same situation maybe I did something wrong but  I found another decision I have created a field Context thisContext inside my Fragment And got a current context from method onCreateView and now I can work with shared pref from fragment      public View onCreateView  NonNull LayoutInflater inflater  ViewGroup container                               Bundle savedInstanceState              thisContext   container getContext

You can make the SharedPrefences in onAttach method of fragment like this    Override public void onAttach Context context        super onAttach context       SharedPreferences preferences   context getSharedPreferences  pref   0

It is possible to get a context from within a Fragment Just do public class YourFragment extends Fragment        public View onCreateView  NonNull LayoutInflater inflater                               ViewGroup container  Bundle savedInstanceState            final View root   inflater inflate R layout yout fragment layout  container  false              get context here         Context context   getContext               do as you please with the context              if you decide to go with second option         SomeViewModel someViewModel   ViewModelProviders of this  get SomeViewModel class           Context context   homeViewModel getContext               do as you please with the context         return root           You may also attached an AndroidViewModel in the onCreateView method that implements a method that returns the application context public class SomeViewModel extends AndroidViewModel        private MutableLiveData lt ArrayList lt String gt  gt  someMutableData      Context context       public SomeViewModel Application application            super application           context   getApplication   getApplicationContext            someMutableData   new MutableLiveData lt  gt                                      public Context getContext              return context

The method getSharedPreferences is  a method of the Context object  so just calling getSharedPreferences from a Fragment will not work   because it is not a Context   Activity is an extension of Context  so we can call getSharedPreferences from it    So you have to get your applications Context by     this   your fragment SharedPreferences preferences   this getActivity   getSharedPreferences  pref   Context MODE PRIVATE
