Nativescript Vue:如何在滚动ListView时关闭searchBar键盘？

import { ListView, SearchBar } from 'nativescript-ui-listview';

<template>
  <Page>
    <ActionBar title="My App" />
    <StackLayout>
      <SearchBar @submit="onSubmit" />
      <ListView ref="listView" @scroll="onScroll">
        <!-- ListView内容 -->
      </ListView>
    </StackLayout>
  </Page>
</template>

export default {
  methods: {
    onScroll(args) {
      const listView = args.object;
      const searchBar = this.$refs.listView.nativeView
        .parent
        .getViewById('searchBarId'); // 替换为你的searchBar的id

      searchBar.dismissSoftInput(); // 关闭键盘
    },
    onSubmit() {
      // 处理searchBar的提交事件
    },
  },
};
