鸿蒙Swiper动态加载翻页数据（等同于安卓动态加载viewPager）

我这里是加载一个实体类列表 类似 List 的数据，那么首先写一个dataSource：

export class MyDataSource implements IDataSource {private list: MyBean[] = []constructor(list: MyBean[]) {this.list = list}totalCount(): number {return this.list.length}getData(index: number): MyBean{return this.list[index]}registerDataChangeListener(listener: DataChangeListener): void {}unregisterDataChangeListener() {}
}

然后在代码中加入

@Entry
@Component
struct SwiperExample {private swiperController: SwiperController = new SwiperController()private data: MyDataSource = new MyDataSource([])aboutToAppear(): void {//在DataSource中放入你自己的list数据let list: MyBean[] = []for (let i = 1; i <= 10; i++) {let b = MyBean()list.push(b);}this.data = new MyDataSource(list)}build() {Column() {Swiper(this.swiperController) {LazyForEach(this.data, (item: MyBean, index:number) => {//这里写viewpager中的布局Text(`${index}`)}).indicator(false)}}}
}
