HarmonyOS 鸿蒙Next List刷新问题

楼主，我也遇到了你说的这个问题，能帮我看下我的代码吗？要怎么使用这个[@Watch](/user/Watch)呢。

 /**
   * 通过父节点获取的子节点数据集合
   */
  [@Prop](/user/Prop) [@Watch](/user/Watch)("ddd") nodeList: NodePersonEntity[] = []
ddd(propName: string) {
this.build()
}
build() {
Column() {
Row() {
Checkbox({ name: “check_select_all” })
.shape(CheckBoxShape.CIRCLE)
.onChange((value: boolean) => {
console.info(‘Checkbox1 change is’ + value)
})
Text($r(‘app.string.select_all’)).margin({ left: 12 })
}.padding({ left: 8, right: 8 }).alignSelf(ItemAlign.Start)
  List() {
    ForEach(<span class="hljs-keyword"><span class="hljs-keyword">this</span></span>.nodeList, (item: NodePersonEntity, index: number) =&gt; {
      ListItem() {
        RelativeContainer() {
          Row() {
            Checkbox().shape(CheckBoxShape.CIRCLE).onChange((value: boolean) =&gt; {

            }).select(item.isSelected)
            Text(item.name.length &gt; <span class="hljs-number"><span class="hljs-number">2</span></span> ? item.name.substring(<span class="hljs-number"><span class="hljs-number">0</span></span>, <span class="hljs-number"><span class="hljs-number">2</span></span>) : item.name)
              .width(<span class="hljs-number"><span class="hljs-number">50</span></span>)
              .height(<span class="hljs-number"><span class="hljs-number">50</span></span>)
              .backgroundColor(<span class="hljs-string"><span class="hljs-string">'#ff4879e8'</span></span>)
              .fontColor(Color.White)
              .padding(<span class="hljs-number"><span class="hljs-number">12</span></span>)
              .borderRadius(<span class="hljs-number"><span class="hljs-number">100</span></span>)
              .fontSize(<span class="hljs-number"><span class="hljs-number">13</span></span>)
              .textAlign(TextAlign.Center)
              .margin({ left: <span class="hljs-number"><span class="hljs-number">12</span></span> })
            Text(item.name).margin({ left: <span class="hljs-number"><span class="hljs-number">12</span></span> })
          }
          .alignItems(VerticalAlign.Center)
          .alignRules({ center: { anchor: <span class="hljs-string"><span class="hljs-string">"__container__"</span></span>, align: VerticalAlign.Center } })

          Row() {
            Image($r(<span class="hljs-string"><span class="hljs-string">'app.media.icon_arrow_right'</span></span>))
              .width(<span class="hljs-number"><span class="hljs-number">32</span></span>)
              .height(<span class="hljs-number"><span class="hljs-number">32</span></span>)
              .objectFit(ImageFit.Contain)
              .padding(<span class="hljs-number"><span class="hljs-number">4</span></span>)
            Image($r(<span class="hljs-string"><span class="hljs-string">'app.media.icon_tongxunlu_nextnode'</span></span>)).width(<span class="hljs-number"><span class="hljs-number">32</span></span>).height(<span class="hljs-number"><span class="hljs-number">32</span></span>).objectFit(ImageFit.Contain)
            Text($r(<span class="hljs-string"><span class="hljs-string">'app.string.text_next_node'</span></span>))
          }
          .visibility(item.id.endsWith(<span class="hljs-string"><span class="hljs-string">"u"</span></span>) ? Visibility.None : Visibility.Visible)
          .alignItems(VerticalAlign.Center)
          .alignRules({
            right: { anchor: <span class="hljs-string"><span class="hljs-string">"__container__"</span></span>, align: HorizontalAlign.End },
            center: { anchor: <span class="hljs-string"><span class="hljs-string">"__container__"</span></span>, align: VerticalAlign.Center }
          })
          .padding({ left: <span class="hljs-number"><span class="hljs-number">8</span></span>, right: <span class="hljs-number"><span class="hljs-number">8</span></span> })
          .onClick(() =&gt; {
            <span class="hljs-keyword"><span class="hljs-keyword">this</span></span>.context.eventHub.emit(EventHubConstant.SELECT_NODE_PERSON_NEXT_NODE, item)
          })
        }.width(<span class="hljs-string"><span class="hljs-string">'100%'</span></span>).height(<span class="hljs-number"><span class="hljs-number">60</span></span>).onClick(() =&gt; {
          item.isSelected = <span class="hljs-literal"><span class="hljs-literal">true</span></span>
          <span class="hljs-keyword"><span class="hljs-keyword">this</span></span>.nodeList[index] = item
        })
      }.padding({ left: <span class="hljs-number"><span class="hljs-number">8</span></span>, right: <span class="hljs-number"><span class="hljs-number">8</span></span> })
    })
  }.margin({ top: <span class="hljs-number"><span class="hljs-number">12</span></span> })
}.padding({ top: <span class="hljs-number"><span class="hljs-number">8</span></span>, bottom: <span class="hljs-number"><span class="hljs-number">8</span></span> })
}<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

我在下面的onClick事件中修改了item的isSelected属性，然后想刷新整个列表显示。
