HarmonyOS 鸿蒙Next list如何展示分割线？要自己添加控件吗？

// xxx.ets
[@Entry](/user/Entry)
[@Component](/user/Component)
struct ListExample {
  private arr: number[] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
build() {
Column() {
List({ space: 20, initialIndex: 0 }) {
ForEach(this.arr, (item: number) => {
if(item !== 0){
ListItem() {
Text(’’ + item)
.width(‘100%’).height(100).fontSize(16)
.textAlign(TextAlign.Center).borderRadius(10).backgroundColor(0xFFFFFF)
}
}
}, (item: string) => item)
}
.listDirection(Axis.Vertical) // 排列方向
.scrollBar(BarState.Off)
.friction(0.6)
.divider({ strokeWidth: 2, color: 0xFFFFFF, startMargin: 20, endMargin: 20 }) // 每行之间的分界线
.edgeEffect(EdgeEffect.Spring) // 边缘效果设置为Spring
.onScrollIndex((firstIndex: number, lastIndex: number, centerIndex: number) => {
console.info(‘first’ + firstIndex)
console.info(‘last’ + lastIndex)
console.info(‘center’ + centerIndex)
})
.onScroll((scrollOffset: number, scrollState: ScrollState) => {
console.info(onScroll scrollState = ScrollState + scrollState + , scrollOffset = + scrollOffset)
})
.width(‘90%’)
}
.width(‘100%’)
.height(‘100%’)
.backgroundColor(0xDCDCDC)
.padding({ top: 5 })
}
}<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

divider就是添加分割线的属性，参考链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/ts-container-list-0000001862607449#ZH-CN_TOPIC_0000001862607449__%E7%A4%BA%E4%BE%8B1，
如果给List加上divider（分割线）没办法隐藏个别分割线，可以单独给想要显示分割线的地址加上相应的分割线，参考如下demo:

@Entry
@Component
struct ListExample {
private arr: number[] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

build() {
Column() {
List({ space: 20, initialIndex: 0 }) {
ForEach(this.arr, (item: number) => {
if (item === 0) {
ListItem() {
Column() {
Text(’’ + item)
.width(‘100%’)
.height(100)
.fontSize(16)
.textAlign(TextAlign.Center)
.borderRadius(10)
.backgroundColor(0xFFFFFF)
}
}
}else{
ListItem() {
Column() {
Text(’’ + item)
.width(‘100%’)
.height(100)
.fontSize(16)
.textAlign(TextAlign.Center)
.borderRadius(10)
.backgroundColor(0xFFFFFF)
Divider().strokeWidth(2).color(’#f00’).margin({top:20,bottom:10})
}
}
}
}, (item: string) => item)
}
.listDirection(Axis.Vertical) // 排列方向
.scrollBar(BarState.Off)
.friction(0.6)
// .divider({ strokeWidth: 2, color: 0xFFFFFF, startMargin: 20, endMargin: 20 }) // 每行之间的分界线
.edgeEffect(EdgeEffect.Spring) // 边缘效果设置为Spring
.onScrollIndex((firstIndex: number, lastIndex: number, centerIndex: number) => {
console.info(‘first’ + firstIndex)
console.info(‘last’ + lastIndex)
console.info(‘center’ + centerIndex)
})
.onScroll((scrollOffset: number, scrollState: ScrollState) => {
console.info(onScroll scrollState = ScrollState + scrollState + , scrollOffset = + scrollOffset)
})
.width(‘90%’)
}
.width(‘100%’)
.height(‘100%’)
.backgroundColor(0xDCDCDC)
.padding({ top: 5 })
}
}<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>
