Date Picker Dialog Box (DatePickerDialog)
A date picker dialog box is a dialog box that allows users to select a date from the given range.
NOTE
The APIs of this module are supported since API version 8. Updates will be marked with a superscript to indicate their earliest API version.
The functionality of this module depends on UI context. This means that the APIs of this module cannot be used where the UI context is unclear. For details, see UIContext.
Since API version 10, you can use the showDatePickerDialog API in UIContext, which ensures that the date picker dialog box is shown in the intended UI instance.

Example
NOTE
For clarity in UI execution context, you are advised to use the showDatePickerDialog API in UIContext.
Example 1: Setting the Display Time
This example demonstrates how to set the display time using showTime, useMilitaryTime, and dateTimeOptions.
// xxx.ets
@Entry
@Component
struct DatePickerDialogExample {
selectedDate: Date = new Date("2010-1-1")
build() {
Column() {
Button("DatePickerDialog")
.margin(20)
.onClick(() => {
DatePickerDialog.show({
// You are advised to use this.getUIContext().showDatePickerDialog().
start: new Date("2000-1-1"),
end: new Date("2100-12-31"),
selected: this.selectedDate,
showTime: true,
useMilitaryTime: false,
dateTimeOptions: { hour: "numeric", minute: "2-digit" },
onDateAccept: (value: Date) => {
// Use the setFullYear method to set the date when the OK button is touched. In this way, when the date picker dialog box is displayed again, the selected date is the date last confirmed.
this.selectedDate = value
console.info("DatePickerDialog:onDateAccept()" + value.toString())
},
onCancel: () => {
console.info("DatePickerDialog:onCancel()")
},
onDateChange: (value: Date) => {
console.info("DatePickerDialog:onDateChange()" + value.toString())
},
onDidAppear: () => {
console.info("DatePickerDialog:onDidAppear()")
},
onDidDisappear: () => {
console.info("DatePickerDialog:onDidDisappear()")
},

// xxx.ets
@Entry
@Component
struct DatePickerDialogExample {
selectedDate: Date = new Date("2010-1-1")
build() {
Column() {
Button("DatePickerDialog")
.margin(20)
.onClick(() => {

},
onDateAccept: (value: Date) => {
// Use the setFullYear method to set the date when the OK button is touched. In this way, when the date picker dialog box is displayed again, the selected date is the date last confirmed.
this.selectedDate = value
console.info("DatePickerDialog:onDateAccept()" + value.toString())
},
onCancel: () => {
console.info("DatePickerDialog:onCancel()")
},
onDateChange: (value: Date) => {
console.info("DatePickerDialog:onDateChange()" + value.toString())
},
onDidAppear: () => {
console.info("DatePickerDialog:onDidAppear()")
},
onDidDisappear: () => {
console.info("DatePickerDialog:onDidDisappear()")
},
onWillAppear: () => {
console.info("DatePickerDialog:onWillAppear()")
},
onWillDisappear: () => {
console.info("DatePickerDialog:onWillDisappear()")
