卡片

一个用于在样式化容器中显示内容的 Jetpack Compose 卡片组件。

Android
Included in Expo Go
Recommended version:
~56.0.16

Expo UI Card 与官方 Jetpack Compose Card API 保持一致,并在带样式的表面容器中显示内容,可选支持阴影高度和边框。Card 组件渲染的是 填充卡片,而 ElevatedCardOutlinedCard 分别提供带抬升效果和带边框的变体。

填充、抬升和描边的 Material 3 卡片

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

基础卡片

BasicCardExample.tsx
import { Host, Card, Text } from '@expo/ui/jetpack-compose'; import { paddingAll } from '@expo/ui/jetpack-compose/modifiers'; export default function BasicCardExample() { return ( <Host matchContents> <Card> <Text modifiers={[paddingAll(16)]}>这是一个具有默认样式的基础卡片。</Text> </Card> </Host> ); }

卡片类型

使用 Card(填充)、ElevatedCardOutlinedCard 来呈现不同样式。

CardTypesExample.tsx
import { Host, Card, ElevatedCard, OutlinedCard, Text, Column } from '@expo/ui/jetpack-compose'; import { paddingAll } from '@expo/ui/jetpack-compose/modifiers'; export default function CardTypesExample() { return ( <Host matchContents> <Column verticalArrangement={{ spacedBy: 12 }}> <Card> <Text modifiers={[paddingAll(16)]}>填充卡片</Text> </Card> <ElevatedCard> <Text modifiers={[paddingAll(16)]}>抬升卡片</Text> </ElevatedCard> <OutlinedCard> <Text modifiers={[paddingAll(16)]}>描边卡片</Text> </OutlinedCard> </Column> </Host> ); }

自定义阴影高度

使用 elevation 属性(单位为 dp)来控制阴影深度。阴影高度在 ElevatedCard 上最有意义,因为它使用的是阴影高度。填充型 Card 默认使用色调阴影高度,因此变化可能会比较细微。

ElevatedCardExample.tsx
import { Host, ElevatedCard, Text } from '@expo/ui/jetpack-compose'; import { paddingAll } from '@expo/ui/jetpack-compose/modifiers'; export default function ElevatedCardExample() { return ( <Host matchContents> <ElevatedCard elevation={8}> <Text modifiers={[paddingAll(16)]}>具有 8dp 阴影高度的卡片</Text> </ElevatedCard> </Host> ); }

自定义边框

CardOutlinedCard 接受 border 属性,用于自定义描边宽度和颜色。

OutlinedCardExample.tsx
import { Host, OutlinedCard, Text } from '@expo/ui/jetpack-compose'; import { paddingAll } from '@expo/ui/jetpack-compose/modifiers'; export default function OutlinedCardExample() { return ( <Host matchContents> <OutlinedCard border={{ width: 2, color: '#6200EE' }}> <Text modifiers={[paddingAll(16)]}>带自定义紫色边框的卡片</Text> </OutlinedCard> </Host> ); }
