上面是做完后的效果，第一次用java来做自定义继承button类控件，如图看到的其实就只有一个经改写的button控件，style_1、2、3、4 是button内部的几个小label而已，不过中间的滑动效果做得不太好，滑动时有闪烁，还请高手们指点指点啦......
如图里的style_1、2...是可以自己在外部添加自定义 listener ，调用如下：
myjb.addJblListener("1", new lblistener_1()); myjb.addJblListener("2", new lblistener_2()); myjb.addJblListener("3", new lblistener_3()); myjb.addJblListener("4", new lblistener_4());这样
再实现lblistener_1方法来，第一次写博文，没啥经验，如有不好的地方请大家不要太在意啦。。呵呵~
好，废话不多说了，直接上代码吧。。。
