芯片
用于显示紧凑元素的 Jetpack Compose 芯片组件。
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:AssistChip、FilterChip、InputChip 和 SuggestionChip。

安装
- npx expo install @expo/uiIf 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。
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。
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。
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。
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> ); }
API
import { AssistChip, FilterChip, InputChip, SuggestionChip } from '@expo/ui/jetpack-compose';
Components
