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

带权重的 Spacer

使用 weight() 修饰符让 spacer 在 RowColumn 中按比例填充可用空间。

SpacerWeightExample.tsx
import { Host, Row, Spacer, Text } from '@expo/ui/jetpack-compose'; import { fillMaxWidth, weight } from '@expo/ui/jetpack-compose/modifiers'; export default function SpacerWeightExample() { return ( <Host matchContents> <Row modifiers={[fillMaxWidth()]}> <Text>左侧</Text> <Spacer modifiers={[weight(1)]} /> <Text>右侧</Text> </Row> </Host> ); }

固定大小的 Spacer

使用 heightwidth 修饰符创建一个具有固定尺寸的 spacer。

SpacerFixedSizeExample.tsx
import { Host, Column, Spacer, Text } from '@expo/ui/jetpack-compose'; import { height } from '@expo/ui/jetpack-compose/modifiers'; export default function SpacerFixedSizeExample() { return ( <Host matchContents> <Column> <Text>上方</Text> <Spacer modifiers={[height(24)]} /> <Text>下方(24dp 间距)</Text> </Column> </Host> ); }

API

import { Spacer } from '@expo/ui/jetpack-compose';
