参考文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/arkts-common-components-custom-dialog-V5

参考demo：

import router from '@ohos.router';
@CustomDialog
export default struct UserPrivacyDialog {
  controller: CustomDialogController = new CustomDialogController({ builder: '' });
  cancel: Function = () => {
  };
  confirm: Function = () => {
  };
  visible: Visibility = Visibility.None
  build() {
    Column() {
      Text('我是弹窗')
      Button('jump')
        .onClick(() => {
          router.pushUrl({
            url: 'pages/Second'
          })
        }).backgroundColor(0xffffff).fontColor(Color.Red)
    }
    .margin({ top: 22 })
    .justifyContent(FlexAlign.SpaceEvenly)
  }
}
