Expo UI Chips 与官方 Jetpack Compose Chip API 保持一致。每种 chip 类型都是独立组件：AssistChip、FilterChip、InputChip 和 SuggestionChip。

安装

Terminal

- npx expo install @expo/ui

If you are installing this in an existing React Native app, make sure to install expo in your project.

用法

Assist chip

Assist chips 帮助用户执行操作或开始任务，例如预订航班或打开地图。它们通常作为对用户输入的响应而出现的临时 UI 元素。

AssistChipExample.tsx

import { Host, AssistChip, Icon, Text } from '@expo/ui/jetpack-compose';

export default function AssistChipExample() {
  return (
    <Host matchContents>
      <AssistChip onClick={() => console.log('Opening flight booking...')}>
        <AssistChip.Label>
          <Text>Book Flight</Text>
        </AssistChip.Label>
        <AssistChip.LeadingIcon>
          <Icon source={require('./assets/flight.xml')} size={18} />
        </AssistChip.LeadingIcon>
      </AssistChip>
    </Host>
  );
}

Filter chip

Filter chips 允许用户从一组选项中细化内容。它们支持选中状态，通常用于搜索栏或内容筛选。

FilterChipExample.tsx

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

export default function FilterChipExample() {
  const [selected, setSelected] = useState(false);

  return (
    <Host matchContents>
      <FilterChip selected={selected} onClick={() => setSelected(!selected)}>
        <FilterChip.Label>
          <Text>Images</Text>
        </FilterChip.Label>
      </FilterChip>
    </Host>
  );
}

Input chip

Input chips 表示用户输入的离散信息片段，例如文本字段中的标签。它们支持头像、尾随图标，并且可以被移除。

InputChipExample.tsx

import { useState } from 'react';
import { Host, InputChip, Icon, Text, FlowRow } from '@expo/ui/jetpack-compose';

export default function InputChipExample() {
  const [chips, setChips] = useState(['Work', 'Travel', 'News']);

  return (
    <Host matchContents>
      <FlowRow horizontalArrangement={{ spacedBy: 8 }}>
        {chips.map(label => (
          <InputChip
            key={label}
            selected
            onClick={() => setChips(prev => prev.filter(c => c !== label))}>
            <InputChip.Label>
              <Text>{label}</Text>
            </InputChip.Label>
            <InputChip.TrailingIcon>
              <Icon source={require('./assets/close.xml')} size={18} />
            </InputChip.TrailingIcon>
          </InputChip>
        ))}
      </FlowRow>
    </Host>
  );
}

Suggestion chip

Suggestion chips 通过展示动态生成的建议来帮助缩小用户意图范围，例如聊天中的快速回复选项或搜索优化建议。

SuggestionChipExample.tsx

import { Host, SuggestionChip, Text } from '@expo/ui/jetpack-compose';

export default function SuggestionChipExample() {
  return (
    <Host matchContents>
      <SuggestionChip onClick={() => console.log('Searching nearby...')}>
        <SuggestionChip.Label>
          <Text>Nearby</Text>
        </SuggestionChip.Label>
      </SuggestionChip>
    </Host>
  );
}
