HarmonyOS 如何先关闭键盘 再关闭弹窗

import { window } from '@kit.ArkUI'

  controller?: CustomDialogController  
  build() {  
    Column() {  
      Text('Change text').fontSize(20).margin({ top: 10, bottom: 10 })

    }.borderRadius(10)

@Entry  
@Component  
struct CustomDialogUser {  
  @State textValue: string = ''  
  @State inputValue: string = 'click me'  
  @State keyboardIsShow: boolean = false // 软键盘是否弹出  
  //窗口的回调，判断键盘的高度（只能判断键盘的起或者终的高度，开发者可以看日志打印，）  
  onPageShow(): void {  
    window.getLastWindow(getContext(this), (err, win) => {
