DialogFragment use

[kassim]

Point 1
Kotterknife behaves in a way that if DialogFragment.getDialog() != null, it will use getDialog().findViewById() or if a getDialog() == null it will attempt getView().findViewById()

The FragmentManager calls getLayoutInflater before onCreateView, and in a DialogFragment onCreateDialog is called as part of getLayoutInflater, therefore there is no point at which a View will exist when a Dialog doesn't.

So I recommend perhaps removing the fallback as to not confuse developers looking at the source.

Point 2

The view created in onCreateView is not set to the dialog until onActivityCreated. Therefore if a behaviour of initialising the view state in onViewCreated is taken then a crash is guaranteed.

There doesn't seem to be a great way of knowing if Dialog.setContentView or FragmentonActivityCreated was called so perhaps this detail should be added to documentation?

I'll make a PR later, but wanted to see if this was agreeable or I'm misunderstanding why I was running into issues.
