datepickerdialog inside a dialog android

I have an activity thats declared as Dialog(using android:theme="@android:style/Theme.Dialog") in my application. The activity should be declared as a Dialog and there is no exception for this.

Inside this dialog, i have a button, that triggers, DatePickerDialog and i have followed the developer's site to implement it.

My problem is, when i declare the "Dialog Activity" as just Activity, I get the datepickerdialog as intended. Below is the image when its just Activity.

How can i achieve the Holo style for the datepickerdialog?

Solution

I had to use, android:theme="@android:style/Theme.Holo.Dialog"to get it to work the way i wanted.
