我有这个code

Foo foo = new Foo();
foo.callTheMethod();

有没有什么办法可以拦截 Foo.callTheMethod（）呼叫而不子类或修改富类，而不必一个富工厂？

Is there any way I can intercept the Foo.callTheMethod() call without subclassing or modifying Foo class, and without having a Foo factory?

编辑：对不起，忘了提，这是Android平台

sorry forgot to mention this is on Android platform.

Have you considered aspect-oriented-programming and perhaps AspectJ ? See here and here for AspectJ/Android info.
