HarmonyOS textinput键盘弹出问题

参考示例如下：

import promptAction from '@ohos.promptAction'

let customDialogId: number = 0

@Builder
function customDialogBuilder() {
  Column() {
    TextInput({ placeholder: 'input your username' }).margin(20)

      .defaultFocus(true)
      .enableKeyboardOnFocus(true)
        //.id("input")
        //.onAppear(() => {
        //focusControl.requestFocus('input')
        //})
      .customKeyboard(CustomKeyboardBuilder())

    Row() {
      Button("确认").onClick(() => {
        promptAction.closeCustomDialog(customDialogId)
      })
      Blank().width(50)
      Button("取消").onClick(() => {
        promptAction.closeCustomDialog(customDialogId)
      })
    }
  }.height(200).padding(5)
}

@Builder
function CustomKeyboardBuilder() {
  Column() {
    Text('这是一个自定义键盘')

    Button('完成')
      .onClick(() => {
        //this.textController.stopEditing()
      })
  }
  .width('100%')
  .height('10%')
  .backgroundColor('#EBEBEB')
}

@Entry
@Component
struct Index {
  @State message: string = '弹窗'

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
            promptAction.openCustomDialog({
              builder: customDialogBuilder.bind(this)
            }).then((dialogId: number) => {
              customDialogId = dialogId
            })
          })
        //普通TextInput
        TextInput({ placeholder: 'input your username' })
          .margin(20)
          .focusable(true)
          .focusOnTouch(true)
          .defaultFocus(true)
          .enableKeyboardOnFocus(true)
      }
      .width('100%')
    }
    .height('100%')
  }
}

如若不行，可以在textInput输入框的onApear回调中将焦点转移到输入框上尝试：

.id("input")
  .onAppear(() => {
    focusControl.requestFocus('input')
  })
