#鸿蒙通关秘籍#如何在OpenHarmony项目中集成PullToRefresh组件？

在OpenHarmony项目中集成PullToRefresh组件需要执行以下步骤：

1. 使用ohpm命令安装PullToRefresh组件：

   ohpm install @ohos/pulltorefresh
   

2. 在你的代码中引入PullToRefresh组件：

   import { PullToRefresh } from '@ohos/pulltorefresh'
   

3. 配置PullToRefresh组件参数并绑定到列表或宫格组件：

   private scroller: Scroller = new Scroller();
   
   PullToRefresh({
     data: $data,
     scroller: this.scroller,
     customList: () => {
       this.getListView();
     },
     onRefresh: () => {
       return new Promise<string>((resolve) => {
         setTimeout(() => {
           resolve('刷新成功');
           this.data = this.dataNumbers;
         }, 2000);
       });
     },
     onLoadMore: () => {
       return new Promise<string>((resolve) => {
         setTimeout(() => {
           resolve('');
           this.data.push("增加的条目" + this.data.length);
         }, 2000);
       });
     },
   });
   

4. 在List组件中关闭边缘效果：

   List({
     ...
   }).edgeEffect(EdgeEffect.None)
