安装

Terminal

- npx expo install @expo/ui

- yarn expo install @expo/ui

- pnpm expo install @expo/ui

- bun expo install @expo/ui

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

使用

基本行

RowExample.tsx

import { useColorScheme } from 'react-native';
import { Host, Row, Text } from '@expo/ui';

export default function RowExample() {
  const colorScheme = useColorScheme();
  const ink = { color: colorScheme === 'dark' ? '#FFFFFF' : '#000000' };

  return (
    <Host matchContents>
      <Row spacing={8}>
        <Text textStyle={ink}>One</Text>
        <Text textStyle={ink}>Two</Text>
        <Text textStyle={ink}>Three</Text>
      </Row>
    </Host>
  );
}

对齐

使用 alignment 沿交叉轴（垂直轴）定位子元素

RowAlignmentExample.tsx

import { useColorScheme } from 'react-native';
import { Host, Row, Text } from '@expo/ui';

export default function RowAlignmentExample() {
  const colorScheme = useColorScheme();
  const ink = { color: colorScheme === 'dark' ? '#FFFFFF' : '#000000' };

  return (
    <Host style={{ width: '100%', height: 160 }}>
      <Row spacing={8} alignment="center">
        <Text textStyle={{ ...ink, fontSize: 30 }}>Large</Text>
        <Text textStyle={ink}>centered</Text>
      </Row>
    </Host>
  );
}

使用 Spacer 分隔内容

将 Row 与可伸缩的 Spacer 结合使用，可将其子元素推向相反的两端

RowSpacerExample.tsx

import { useColorScheme } from 'react-native';
import { Host, Row, Text, Spacer } from '@expo/ui';

export default function RowSpacerExample() {
  const colorScheme = useColorScheme();
  const ink = { color: colorScheme === 'dark' ? '#FFFFFF' : '#000000' };

  return (
    <Host matchContents={{ vertical: true }} style={{ width: '100%' }}>
      <Row>
        <Text textStyle={ink}>Leading</Text>
        <Spacer flexible />
        <Text textStyle={ink}>Trailing</Text>
      </Row>
    </Host>
  );
}

import { Row } from '@expo/ui';
