Create a ValidatingEditTextPreference - in the same way that the FormEditText can be used for EditTexts the ValidatingEditTextPreference can be used in PreferenceActivity and benefit from the same easy xml driven validation.
Create a new 'custom' XML testType - allows for custom validators to be set up in/via XML
Modify FormEditText to delegate all the validation to a new EditTextValidator. This EditTextValidator is used by both the FormEditText and the ValidatingEditTextPreference
Add ValidatingEditTextPreference and example preference/settings to exampleproject
