android-time Picker and date selector

First, the realization of dynamic input date and time
* Datapicker (Calendar selector)
* Datapicker object with init () method specifies DatePicker initial month date and Ondatechangedlistener event
* Timepicker (Time picker)
* Timepicker objects that need to be done directly with Setontimechangedlistener () event processing time changed
*
* Two, dynamic input date and time of the dialog box
* Datapickerdialog
*
* Timepickerdialog
*
* Third, listener
* Ondatechangedlistener
* The Ondatechange () event that triggers the Ondatechangedlistener listener when the user changes the year, month, and day in Datapicker
*
* Ontimechangedlistener
* The Ontimechange () event that triggers the Ontimechangedlistener listener when the user changes the time, minutes, and seconds in Timepicker
*
* Ondatesetlistener
* The Ondateset () event that triggers the Ondatesetlistener listener when the user changes the year, month, and day in Datapickerdialog
*
* Ontimesetlistener
* The Ontimeset () event that triggers the Ontimesetlistener listener when the user changes the time, minutes, and seconds in Timepickerdialog
