1，匿名内部类其实就是内部类的简写格式。

2，定义匿名内部类的前提：

　　内部类必须是继承一个类或者实现接口。

3，匿名内部类的格式： new 父类或者接口(){定义子类的内容}

4，其实匿名内部类就是一个匿名子类对象。而且这个对象有点胖。　　可以理解为带内容的对象。

5，匿名内部类中定义的方法最好不要超过3个。-Anonymous inner classes: 1, anonymous inner class inner class is actually shorthand format. 2, the definition of anonymous inner classes premise: Internal class must inherit a class or implement the interface. 3, the anonymous inner class format: new parent class or interface () {} defines the contents of four subclasses, in fact, an anonymous inner class is a subclass of anonymous objects. Moreover, this object is a little fat. Can be understood as with the content of the object. 5, the anonymous inner class defines methods is best not more than three.
