I'm saving value of the current locale into SharedPreferences,

viewmodel's data should be changed by current locale, so I have to use SharedPreferences..

private fun getPreferences(context: Context): SharedPreferences {
    return context.getSharedPreferences(PREFERENCES_NAME, Context.MODE_PRIVATE)
}

this code needs context , I don't know how can I use SharedPreferences in Viewmodel..

Your ViewModel class should be extend by AndroidViewModel.

after that call getApplication() and use it as context when accessing SharedPreferences.

public class YourViewModel extends AndroidViewModel {

   SharedPreferences sharedpreferences = getApplication().getSharedPreferences("pref_key", Context.MODE_PRIVATE);

   String varName = sharedpreferences.getString("var_name", "")

}
