HStack

一个用于水平布局的 SwiftUI HStack 组件。

iOS

tvOS

Included in Expo Go

GitHub

npm

更新日志

有关跨平台使用，请参阅通用的 Row — 它会根据平台渲染相应的原生组件。

Expo UI HStack 与官方 SwiftUI HStack API 一致，并将其子元素水平排列。

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

基本水平堆栈

BasicHStackExample.tsx

import { Host, HStack, Text } from '@expo/ui/swift-ui';

export default function BasicHStackExample() {
  return (
    <Host matchContents>
      <HStack spacing={12}>
        <Text>第一</Text>
        <Text>第二</Text>
        <Text>第三</Text>
      </HStack>
    </Host>
  );
}

使用对齐

alignment 属性控制子元素的垂直对齐方式。可用选项包括：top、center、bottom、firstTextBaseline 和 lastTextBaseline。

HStackAlignmentExample.tsx

import { Host, HStack, Rectangle } from '@expo/ui/swift-ui';
import { frame } from '@expo/ui/swift-ui/modifiers';

export default function HStackAlignmentExample() {
  return (
    <Host matchContents>
      <HStack spacing={12} alignment="top">
        <Rectangle modifiers={[frame({ width: 50, height: 50 })]} />
        <Rectangle modifiers={[frame({ width: 50, height: 100 })]} />
        <Rectangle modifiers={[frame({ width: 50, height: 75 })]} />
      </HStack>
    </Host>
  );
}
