用法

基本列表项

BasicListItem.tsx

import { Host, ListItem, Text } from '@expo/ui/jetpack-compose';

export default function BasicListItem() {
  return (
    <Host matchContents>
      <ListItem>
        <ListItem.HeadlineContent>
          <Text>Settings</Text>
        </ListItem.HeadlineContent>
      </ListItem>
    </Host>
  );
}

使用复合组件

使用复合组件在每个位置显示丰富内容。

ListItemWithCompoundComponent.tsx

import {
  Host,
  ListItem,
  Icon,
  Text,
} from '@expo/ui/jetpack-compose';

export default function ListItemWithSlots() {
  return (
    <Host matchContents>
      <ListItem>
        <ListItem.HeadlineContent>
          <Text>Notifications</Text>
        </ListItem.HeadlineContent>
        <ListItem.OverlineContent>
          <Text>ACCOUNT</Text>
        </ListItem.OverlineContent>
        <ListItem.SupportingContent>
          <Text>Manage notification preferences</Text>
        </ListItem.SupportingContent>
        <ListItem.LeadingContent>
          <Icon source={require('./assets/notifications.xml')} />
        </ListItem.LeadingContent>
        <ListItem.TrailingContent>
          <Icon source={require('./assets/chevron.xml')} />
        </ListItem.TrailingContent>
      </ListItem>
    </Host>
  );
}

可点击的列表项

使用 clickable 修饰符处理点击交互。

ClickableListItem.tsx

import { Host, ListItem, Text } from '@expo/ui/jetpack-compose';
import { clickable } from '@expo/ui/jetpack-compose/modifiers';

export default function ClickableListItem() {
  return (
    <Host matchContents>
      <ListItem
        modifiers={[clickable(() => console.log('Tapped!'))]}>
        <ListItem.HeadlineContent>
          <Text>Tap me</Text>
        </ListItem.HeadlineContent>
      </ListItem>
    </Host>
  );
}

自定义标题内容

使用 ListItem.HeadlineContent 编写可组合的标题内容，例如带图标的行。

ListItemCustomHeadline.tsx

import {
  Host,
  ListItem,
  Text,
  Row,
  Icon,
} from '@expo/ui/jetpack-compose';

export default function ListItemCustomHeadline() {
  return (
    <Host matchContents>
      <ListItem>
        <ListItem.HeadlineContent>
          <Row
            horizontalArrangement={{ spacedBy: 8 }}
            verticalAlignment="center">
            <Text>Premium Feature</Text>
            <Icon source={require('./assets/star.xml')} size={16} />
          </Row>
        </ListItem.HeadlineContent>
      </ListItem>
    </Host>
  );
}
