模板方法模式定义：defines the skeleton of an algorithm in a method, deferring some steps to subclasses. Template Method lets subclasses redefine certain steps of an algorithm without changing the algorithm's structure.定义一个方法操作算法的框架（骨架结构），而将一些步骤延迟到子类中。 阅读全文

一、Android源码学习之装饰模式应用装饰模式定义：Attach additional responsibilities to an object dynamically keeping the same interface. Decoators provide a flexible alternative to subclassing for extending functionality.动态地给一个对象添加一些额外的职责。就增加功能来说，装饰模式相比生成子类更为灵活。二、Android源码学习之单例模式应用单例模式定义：Ensure a class has only one insta 阅读全文
