Well, that's about six or seven pages in a book, so it's a bit involved for a StackOverflow answer. :-)

Here is a sample project with a custom View, which is also wrapped into a custom Preference. It is only ~80 lines of code, though much of the UI smarts are bound up in the custom View class.

In a nutshell, to make a custom DialogPreference, you need to define:

• The constructors
• onCreateDialogView() and onBindDialogView() to create the dialog contents and populate the contents with the preference data
• onDialogClosed() to handle when the user changes the preference
• onGetDefaultValue() to handle your overall default if the preference is not yet set
• onSetInitialValue() to either load in the preference value or use your default
