Unable to instantiate fragment make sure class name exists, is public, and has an empty constructor

在android中使用Fragment中,有时候我们会遇到Unable to instantiate fragment make sure class name exists, is public, and has an empty constructor that is public这样的异常,从字面上理解应该是这个我们的自定义Fragment需要一个public没有参数的构造函数,但是有时候即使加上了无参数的public的构造函数,依然出现这个异常。今天我也遇到了这个问题,原来Fragment不能作为内部类,即使作为内部类,我们也要加上static关键字,是不是内部类不能通过反射来创建实例,这个还要去看看Java相关的知识,希望给遇到这个问题的网友提个醒,自定义Fragment要单独定义,不能作为内部类,否则使用会出问题。
