转载之前我想深深地感谢屌丝哥
相信相同过App获取利润的都会需要接入计费SDK，下边就跟大家走一遍完整的支付宝SDK接入，支付系列均通过计费Button触发，计费所有代码均放到一个java文件实现，这样虽然会有点违背java面向对象及封装性，但这样做的一个好处是可以快速集成到不同的游戏中，将改动的文件降到最低，各有利弊吧，如果大家有什么更好的方法，望一起交流，好了，废话不多说了，开始干活。
PS：初次写博文，各方面还不够完善，看到此博文的朋友有什么意见或者建议请回复或者留言，你们的支持是我最大的动力。注意事项1.添加android.permission.INTERNET权限和android.permission.ACCESS_NETWORK_STATE权限2.代码中出现注释的地方重点看，没注释的地方可以不看3.想获取支付宝合作商户ID，及支付宝公钥请点击支付宝链接，生成密钥及PKCS8转码工具在文档中代码 MainActivity：
