DatePickerDialog

Hi Guys!
Today I am going to share about the code of Date Picker in Android.
This class is a widget for selecting a date. The date can be selected by a year, month, and day spinners or a CalendarView. The set of spinners and the calendar view are automatically synchronized. The client can customize whether only the spinners, or only the calendar view, or both to be displayed. Also the minimal and maximal date from which dates to be selected can be customized.
For detail about the Date Picker you can visit the android developer site Date Picker.

So lets start the coding about the date picker android.
