外观模式在安卓系统中例子
这里的例子选用有问题。
Context-ContextWrapper-Activity 之间不是外观模式
原因在于：
从形式上看，外观模式的Facade一般不会继承自被外观类，以便隐藏原有的接口信息，同时简化本来复杂系统的使用。
从功能上看，Context的子类在持有Context对象的同时动态的为Context添加新的的内容或者改变其中的信息，而完成这种职责的一般是装饰者模式。
综上所述，Context-ContextWrapper-Activity/Application/Service... 这些之间的关系使用的应该是装饰者模式而不是外观模式.
AdapterView 与Adapter 间的模式
我觉得AdapterView与Adapter间并不是桥接模式吧？桥接模式的意图是将抽象与它的实现分开变化，AdapterView是一个View，而Adapter是一个适配器接口，AdapterView我觉得只是适配器模式的一个Client。AdapterView是泛型或模板方法，如果说他们之间是桥接模式，感觉有点牵强。
Seems useful
If possible, have someone to translate this to English, please :)
可否完善其他设计模式呢，Android源码设计模式与实战的忠实读者
可否完善其他设计模式呢，Android源码设计模式与实战的忠实读者。书写实在是太好了，精简、易懂、实用。源码解析能否补充一下，让大家共享
单例模式--实现方式二：为何“不能完全避免并发带来的破坏”
请问double-check方式哪里会有并发带来的破坏呢？
创建的话是可以避免多次创建的：如果已经创建过，任何读得线程都可以直接返回；如果未创建，则第一个进入if分支的线程持有锁，其他线程都要等待，因为有double-check，所以其他线程也不会再次创建；
这样子读取过程也没问题吧？
关于外观模式
外观模式第3小节电视遥控器的例子，测试代码部分貌似没写~直接把外观层copy下来了
