在做开发的过程中,序列化是非常常见的.比如要将对象保存本地磁盘或者在网络上传输等.实现序列化有两种方式,一种是实现Serializable接口,第二种是实现Parcelable. Serializable与Parcelable的区别 1.Serializable是JDK提供的接口,而Parcelable是Android SDK提供的. 2.Serializable序列化是基于磁盘的,而Parcelable是基于内存的.在内存中读写肯定效率要高于磁盘,所以Android中跨进程传递对象都是使用Pa…

Android中的接口回调技术有很多应用的场景,最常见的:Activity(人机交互的端口)的UI界面中定义了Button,点击该Button时,执行某个逻辑. 下面参见上述执行的模型,讲述James对Android接口回调技术的理解(结合前人的知识和自己的实践). 使用一个比喻很形象地说明:客户端有个疑问打电话请教服务端,但服务端无法现场给出解答,相互之间约定:服务端一旦有答案,使用电话的方式反馈给客户端. 以上有三个主体:客户端.服务端和接口(方式). 接口回调的原理框图说明: Demo界面…
