用法

🌐 Usage

日期选择器

🌐 Date picker

DatePickerExample.tsx

import { useState } from 'react';
import { Host, DateTimePicker } from '@expo/ui/jetpack-compose';

export default function DatePickerExample() {
  const [selectedDate, setSelectedDate] = useState(new Date());

  return (
    <Host matchContents>
      <DateTimePicker
        onDateSelected={date => {
          setSelectedDate(date);
        }}
        displayedComponents="date"
        initialDate={selectedDate.toISOString()}
        variant="picker"
      />
    </Host>
  );
}

时间选择器

🌐 Time picker

TimePickerExample.tsx

import { useState } from 'react';
import { Host, DateTimePicker } from '@expo/ui/jetpack-compose';

export default function TimePickerExample() {
  const [selectedDate, setSelectedDate] = useState(new Date());

  return (
    <Host matchContents>
      <DateTimePicker
        onDateSelected={date => {
          setSelectedDate(date);
        }}
        displayedComponents="hourAndMinute"
        initialDate={selectedDate.toISOString()}
        variant="picker"
      />
    </Host>
  );
}

输入变体

🌐 Input variant

使用 variant="input" 将选择器显示为文本输入字段，而不是默认的选择器界面。

🌐 Use variant="input" to display the picker as a text input field instead of the default picker UI.

InputVariantExample.tsx

import { useState } from 'react';
import { Host, DateTimePicker } from '@expo/ui/jetpack-compose';

export default function InputVariantExample() {
  const [selectedDate, setSelectedDate] = useState(new Date());

  return (
    <Host matchContents>
      <DateTimePicker
        onDateSelected={date => {
          setSelectedDate(date);
        }}
        displayedComponents="date"
        initialDate={selectedDate.toISOString()}
        variant="input"
      />
    </Host>
  );
}
