How to pick date from the user in Android?
Write an android example to pick date from the user and display it.
Android provides control for the user to pick a date through a pre-defined dialog box. Picker provides control for selecting each part of the date i.e. month, day, and year. Pickers help us to ensure that users can pick a date that is valid, formatted correctly, and adjusted to the user's locale.
In this tutorial, we are going to ask the user to input the date with the help of date picker and with the simple one click show button user can view the date entered.
Date class is required to hold the data set by the picker.
Data members inside the Date class are static to access the data from the MainActivity. Static data members of the class were created only for the first time when the object of that class has been created.
Use
DialogFragment class to host each time or date picker, the
DialogFragment class manages the dialog lifecycle for you and allows you to display the pickers in different layout configurations.
