HarmonyOS 如何设置输入法底部弹出的时候，把底部内容顶起来。

请参考demo

import window from '@ohos.window';
import { webview } from '@kit.ArkWeb';

@Entry
@Component
struct Index {
  @State screenHeight: number = 0;
  mWebviewController: webview.WebviewController = new webview.WebviewController();

  aboutToAppear() {
    window.getLastWindow(getContext(this)).then(currentWindow => {
      let property = currentWindow.getWindowProperties();
      let avoidArea = currentWindow.getWindowAvoidArea(window.AvoidAreaType.TYPE_KEYBOARD);
      // 初始化显示区域高度
      this.screenHeight = px2vp(property.windowRect.height - avoidArea.bottomRect.height);
      // 监视软键盘的弹出和收起
      currentWindow.on('avoidAreaChange', async data => {
        if (data.type !== window.AvoidAreaType.TYPE_KEYBOARD) {
          return;
        }
        this.screenHeight = px2vp(property.windowRect.height - data.area.bottomRect.height);
      })
    })
  }

  build() {
    Column() {
      Row(){
        Text("Title").alignSelf(ItemAlign.Center).height(44)
      }
      Web({ src: 'https://test-b-fat.pingan.com.cn/ibank/member/example/index17.html', controller: this.mWebviewController })
        .backgroundColor(Color.White)
        .layoutWeight(1)
    }
    .width('100%').height(this.screenHeight -44)
  }
}
