HarmonyOS鸿蒙Next中关于TextInput的讨论

可以试下通过在onScrollFrameBegin事件中调用stopEditing退出编辑态，实现滚动时收起软键盘，具体使用可以参考文档：

如：

@Entry
@Component
struct ScrollDemo {
  @State text: string = 'TextInput'
  scroller: Scroller = new Scroller()
  controller: TextInputController = new TextInputController()
  arr: number[] = [];
  aboutToAppear(): void {
    for (let index = 0; index < 20; index++) {
      this.arr[index] = index;
    }
  }
  build() {
    Column() {
      Scroll(this.scroller) {
        Column() {
          TextInput({ controller: this.controller, text: this.text })
            .width('95%')
            .height(50)
            .margin({ top: 100 })
          List() {
            ForEach(this.arr, (item: number, index: number) => {
              ListItem() {
                Text('Text' + item)
                  .fontSize('25fp')
                  .margin({
                    top: '10vp',
                    bottom: '10vp'
                  })
              }
            })
          }
        }
      }
      .onScrollFrameBegin((offset: number, state: ScrollState) => {
        this.controller.stopEditing()
        return { offsetRemain: offset }
      })
    }.height('100%')
  }
}
