How do I customise a preference to display a time picker widget through XML

Firstly I'd like to say that I have only been working on Android for about a week now, so I guess you can consider me a newb! Therefore I apologise in advance if the solution is overly simple, but I can assure you that I have done my research before posting here, and haven't found an appropriate solution as of yet (or maybe I have and don't fully realise it!). Nonetheless, having lots of fun and just want to solve this problem and learn, so here goes...

The Application

The application I am developing is essentially a reminder service, and I am currently working on the preferences screen.

The Problem

I would like the user to be able to specifiy a time when he/she will be reminded daily. I want this selection to be done via the preferences screen. This is how my preferences screen looks so far...

My Question

Ideally, whenever the user selects the "Alarm Time" preference, I would like the following to appear (this is a screenshot of a preference from another application - PillReminder).

Preference with Time Picker widget (taken from another app - "PillReminder")

My question is, what is the best way to create this? I really want to keep all the visual aspects of the application using only XML, therefore I don't want a Java solution. Is this possible or am I completely off track? Other potential solutions I have heard of are using themes, alert dialogs and extending preference classes etc. Maybe some of these are correct, but I am unsure.

Any help would be greatly appreciated, thanks! :)

That is probably a custom DialogPreference that happens to have a TimePicker in it.

Custom preferences like this cannot be defined in XML. You will need to create a subclass of DialogPreference, define what goes in the dialog, and how the dialog's contents can be stored to (and retrieved from) a SharedPreference value.

My ColorMixer CWAC project has a ColorPreference that you may wish to examine.
