HarmonyOS 如何实现可展开的listview功能

参考示例如下：

@Entry
@Component
struct List0812 {
  @State textHt: number = 30
  @State selectedIndex: number = 0;
  @State list: number[] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
  @State heightList: number[] = [this.textHt, 0, 0, 0, 0, 0, 0, 0, 0, 0];

  build() {
    Column() {
      List() {
        ForEach(this.list, (item: number, index) => {
          ListItem() {
            Column() {
              Text('text_' + item)
                .onClick(() => {
                  this.selectedIndex = index;
                  this.heightList.forEach((v, i) => {
                    if (i === this.selectedIndex) {
                      this.heightList[i] = this.textHt;
                    } else {
                      this.heightList[i] = 0;
                    }
                  })
                })
                .width('100%')
                .padding(10)
                .height(40)
                .backgroundColor(Color.Pink)

              Column() {
                Text('ui_' + item + '_1')
                  .height(this.heightList[index])
                Text('ui_' + item + '_2')
                  .height(this.heightList[index])
                Text('ui_' + item + '_3')
                  .height(this.heightList[index])
                Text('ui_' + item + '_4')
                  .height(this.heightList[index])
              }
              .width('100%')
              .backgroundColor(Color.Yellow)
            }
          }
        })
      }.width('90%').height('100%')
    }.width('100%').height('100%')
  }
}
