I am writing my little Android app. I pop up a dialog control which is a nice, non-fullscreen, rounded-corners dialog by setting android:theme="@android:style/Theme.Dialog" on the activity in my manifest. That all works just as I expected. However it is just a drab, grey-titled dialog as in this screenshot:

I’ve noticed however that a LOT of applications, when they pop up dialogs have a nice, blue-themed title as in this screen shot.

I would assume this theme is some common theme, as it shows up in a LOT of different apps. I would assume it is something built in to the OS. (My phone is a Captivate with the official Froyo release). Of course it COULD be something that every developer simply re-coded on their own, but I doubt that.
Assuming that this is a common theme, how do I utilize it in my app? What changes do I need to make to my activity to have it use that theme?
Thanks in advance!
You can set your activity to use a default theme like Theme.Black. There are default themes and they are in R.style – although i’m not sure which are available to which platforms(i.e. i think the holo themes are for 3.0 and up…

see here http://developer.android.com/guide/topics/ui/themes.html for defining your own custom themes and scroll all the way down for using the “platform styles” and themes.
