监听屏幕旋转的案例有哪些

import { mediaquery } from '@kit.ArkUI';
let listener = mediaquery.matchMediaSync('(orientation: landscape)'); // 监听横屏事件
function onPortrait(mediaQueryResult: mediaquery.MediaQueryResult) {
  if (mediaQueryResult.matches) {
   // do something here
  } else {
   // do something here
  }
}
listener.on('change', onPortrait) // 注册回调
listener.off('change', onPortrait) // 去注册回调
