Exploration of DatePicker and TimePicker in Android Control

1. DatePicker inherits from the FrameLayout class. The date Selection Control provides users with date data including year, month, and day, and allows users to modify the data. To capture Data Events in the user's date Selection control, you need to add an OnDateChangedListener listener for DatePicker.

Ii. TimePicker also inherits from the FrameLayout class. The Time Selection Control displays the time of a day (in 24 hours or AM/PM format) to the user and allows the user to select. To capture the event of the time data modified by the user, you need to add the OnTimeChangedListener listener for the TimePicker.

Usage of the following Date and Time Selection controls
