安卓生成序列化Parcelable接口代码小程序
来源：互联网 发布：矩阵乘法结合律证明 编辑：程序博客网 时间：2024/06/06 09:46
谷歌在安卓上提供了一个序列化接口——Parcelable，它表示比java传统的序列化接口效率更高，然而现实是它不是自动化的，所以它的效果是很坑爹的——要重写很多代码。
于是在安卓studio上，大神就开发了一个基于注解式的插件。。。然而，我对@@@@@很感冒。。。于是自己编写的一个java swing窗体小程序，可以为实体类快速生成实现了Parcelable接口的代码。
通过各种正则表达式，各种折腾，各种解析最终实现。
最后java swing程序运行结果如下：
ok，将生成的代码复制到项目中。。。
以下是解析并生成Parcelable接口代码的部分：
