HarmonyOS 鸿蒙Next怎么自定义ActionSheet的弹框样式

可以使用自定义弹框进行设置，给你个demo参考：

// xxx.ets
[@CustomDialog](/user/CustomDialog)
struct CustomDialogExampleTwo {
 private arr: string[] = ['apples','bananas','pears']
 controllerTwo?: CustomDialogController
 build() {
   Column() {
     Text('ActionSheet title').fontSize(20).margin({ top: 10, bottom: 10 })
     Text('message').fontSize(16).margin({ bottom: 10 })
     List({  space:10,initialIndex:0 }) {
       ForEach(this.arr, (item: number) => {
         ListItem() {
           Text('' + item)
             .width('100%').fontSize(16)
             .textAlign(TextAlign.Center).borderRadius(10).backgroundColor(0xFFFFFF)
         }
       }, (item: string) => item)
     }
     .listDirection(Axis.Vertical)
     .divider({ strokeWidth: 1, color: Color.Gray, startMargin: 100, endMargin: 100 })
     Button('Confirm button')
       .onClick(() => {
         if (this.controllerTwo != undefined) {
           this.controllerTwo.close()
         }
       })
       .width('80%')
       .margin(20)
}
   }
 }
[@Entry](/user/Entry)
[@CustomDialog](/user/CustomDialog)
struct CustomDialogExample {
 dialogControllerTwo: CustomDialogController | null = new CustomDialogController({
   builder: CustomDialogExampleTwo(),
   alignment: DialogAlignment.Bottom,
   offset: { dx: 0, dy: -25 }
 })
 controller?: CustomDialogController
 build() {
   Column() {
     Flex({ justifyContent: FlexAlign.Center,alignItems:ItemAlign.Center }) {
       Button('click')
         .onClick(() => {
           if (this.dialogControllerTwo != null) {
             this.dialogControllerTwo.open()
           }
         })
         .margin(20)
     }.borderRadius(10)
   }
 }
}
