如何从片段中清除共享首选项？

Question

我如何从片段中清除共享偏好？谢谢

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
       sharedPreferences = getActivity().getSharedPreferences("login.conf", Context.MODE_PRIVATE);

        editor = sharedPreferences.edit();
        editor.clear();
        editor.commit();
        Intent logout = new Intent(getActivity(), LoginActivity.class);
        startActivity(logout);
        Log.d(TAG, sharedPreferences.getString("username", ""));
        Log.d(TAG, sharedPreferences.getString("password", ""));
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_fragment_logout, container, false);
    }

那是我的片段

您可以直接使用首选项名称并从任何地方清除它.

SharedPreferences preferences = getSharedPreferences("Mypref", 0);
preferences.edit().remove("shared_pref_key").commit();

要么

SharedPreferences preferences = context.getSharedPreferences("Mypref", Context.MODE_PRIVATE);
preferences .edit().clear().commit();
