前几天看了郭大神的运行时权限的专讲，深受启发，由于现在基于目前项目中的运行时权限封装的还不是那么完美，趁着郭神建议的还是历历在目。于是把它完整的敲了下来。并在此基础上添加上自己的一些见解，封装成一个完整的demo，希望与大家进行交流与。
在这里我进行了简单的在activity中简单进行获取权限和工具类封：
某一个权限被禁止或者是所有的权限被禁止，这里我做了去到烯烃界面去设置的处理：
如果要开启多个权限的话，则可能不同的手机显示的效果不同，有些手机在权限Dialog上显示需要获取权限的个数，但有些手机需要多少个权限显示多少个。
最后一步处理：如果某个权限被禁止的话，则到设置界面去提示用户去打开权限：
部分代码：
