Is there a fast way(or Android Studio plugin) to write mapper class?

[tmac1999]

If a DTO bean has many fields,then write a mapper class could be a huge burden for me,Specially transform a one-layer(only DTO bean) project to two-layer (DTO bean-VO bean)project.I want maintain the exist DTO field to VO and only the new and changed field will need a mapper.

So Is there a fast way(or Android Studio plugin) to write mapper class?

I have considered BeanUtils.copyProperties,but it`s a little bit hard to use in Android Framework.
