Date Picker and Set any specific date using Calender for Android

Current Date and set any specific date from Calender

In This project I am going to show you how date picker works. You can get the current date and
also you can pick any specific date as well.

In main.xml specifying two text view, one is for current date and another is for specific date that you select from calender. After clicking on button, one dialog will appear for calender, you can choose any specific date.
