显示android中片段内模式_PRIVATE的错误

在onCreateView中对SharedReference使用模式_PRIVATE时显示错误

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View layout = inflater.inflate(R.layout.activity_package_categories, container, false);
    SharedPreferences pref = getActivity().getSharedPreferences("PackageType", MODE_PRIVATE);
    SharedPreferences.Editor editor = pref.edit();
    editor.putString("package_categories_id", position);
    editor.commit();
    return layout;
    }

您应该这样使用它

Context.MODE\u PRIVATE

 @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View layout = inflater.inflate(R.layout.activity_package_categories, container, false);
        SharedPreferences pref = getActivity().getSharedPreferences("PackageType", Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = pref.edit();
        editor.putString("package_categories_id", position);
        editor.commit();
        return layout;
        }

在代码中添加上下文，如：

---

SharedReferences pref=getActivity（）.GetSharedReferences（“PackageType”，Context.MODE\u PRIVATE）

应该是

Context.MODE\u PRIVATE
