I want to use AppCompat library, however there is no Dialog theme, and there is no DialogWhenLarge theme which I can either extend or use.
Is there a way I can extend the base theme and make it DialogWhenLarge, probably using folders and custom styling items.
Thanks
Closing this ticket down. For anyone who would like the answer see this.
ActionBar in a DialogFragment
and this custom style in folder values-large
However I think I have decided to go down the route of using a DialogFragment which i can then load into an activity on the phone, or show as a dialog on tablet, rather than this semi-mashed way of turning an activity into a dialog.
