  @BindView(R.id.settings_token)      TextView _tokenMail;
  
  @Nullable
  @Override
  public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
      //returning our layout file
      final View view = inflater.inflate(R.layout.fragment_3_settings, container, false);
      ButterKnife.bind(this, view);
  
      SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this.getContext());
      String email = prefs.getString("email", null);
      String passwd = prefs.getString("password", null);
      String token = prefs.getString("token", null);
      _settingsMail.setText(email);
      _passwordMail.setText(passwd);
      _tokenMail.setText(token);
      return inflater.inflate(R.layout.fragment_3_settings, container, false);
