Android automatically creates a model or PO file

In the development process found that the model or PO layer data is only different parameters, the others are the same, and each time the writing of the same thing will take a lot of time to write or copy. Although some can be generated quickly, but still need time, such as the Parcelable interface implementation of the need to write something, now use a file to write a class to automatically generate files believe that can reduce more time. Even if the development of the interface enough specification, can also directly parse the interface to generate model or PO files.

The source code is as follows:
