傳遞obj給fragment的三種方式

參考：http://stackoverflow.com/questions/10836525/passing-objects-in-to-fragments

There are 3 ways to pass objects to a fragment

They are:

1. Passing the object through a setter is the fastest way, but state will not be restored automatically.
2. setArguments with Serializable objects is the slowest way (but okay for small objects, I think) and you have automatic state restoration.
3. Passing as Parcelable is a fast way (prefer it over 2nd one if you have collection of elements to pass), and you have automatic state restoration.
