芯片

用于显示紧凑元素的 Jetpack Compose 芯片组件。

Android
Included in Expo Go
Recommended version:
~57.0.0

Expo UI Chip 与官方 Jetpack Compose Chip API 保持一致。每种 Chip 类型都是一个独立组件:AssistChipFilterChipInputChipSuggestionChip

筛选、辅助和建议 Material 3 Chips

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

辅助芯片

辅助芯片可帮助用户执行操作或开始任务,例如预订航班或打开地图。它们通常会在响应用户输入时作为临时 UI 元素出现。

AssistChipExample.tsx
import { Host, AssistChip, Icon, Text } from '@expo/ui/jetpack-compose'; export default function AssistChipExample() { return ( <Host matchContents> <AssistChip onClick={() => console.log('正在打开航班预订...')}> <AssistChip.Label> <Text>预订航班</Text> </AssistChip.Label> <AssistChip.LeadingIcon> <Icon source={require('./assets/flight.xml')} size={18} /> </AssistChip.LeadingIcon> </AssistChip> </Host> ); }

筛选芯片

筛选芯片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>图片</Text> </FilterChip.Label> </FilterChip> </Host> ); }

输入芯片

输入芯片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(['工作', '旅行', '新闻']); 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> ); }

建议芯片

建议芯片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细化项。

SuggestionChipExample.tsx
import { Host, SuggestionChip, Text } from '@expo/ui/jetpack-compose'; export default function SuggestionChipExample() { return ( <Host matchContents> <SuggestionChip onClick={() => console.log('正在搜索附近地点...')}> <SuggestionChip.Label> <Text>附近</Text> </SuggestionChip.Label> </SuggestionChip> </Host> ); }
