Android Custom Datatimepicker (date picker)

Android Custom Datatimepicker (date picker)

I have not published an article on Android for some time, about Android custom components I have a few of the author want to share with you, later will be recorded in the blog. This blog for everyone to share is to customize a date selector, you can allow users to select both the date and the current time.
first Look at the effect:

the effect is to display date selection and time selection on the same layout.
To customize a class:/datetimepicker/src/com/wwj/datetimepicker/datetimepickdialogutil.java
