请问一下tab按钮组切换效果

import { 
  ItemRestriction, 
  SegmentButton, 
  SegmentButtonItemTuple, 
  SegmentButtonOptions, 
  SegmentButtonTextItem 
} from '@ohos.arkui.advanced.SegmentButton' 
 
@Entry 
@Component 
struct Index { 
  // 配置按钮组数组 
  @State tabOptions: SegmentButtonOptions = SegmentButtonOptions.tab({ 
    buttons: [ 
      { text: '美妆' }, 
      { text: '衣服' }, 
      { text: '鞋子' } 
    ] as ItemRestriction<SegmentButtonTextItem>, 
    backgroundBlurStyle: BlurStyle.BACKGROUND_THICK 
  }) 
  @State singleSelectCapsuleOptions: SegmentButtonOptions = SegmentButtonOptions.capsule({ 
    buttons: [ 
      { text: '美妆' }, 
      { text: '衣服' }, 
      { text: '鞋子' } 
    ] as SegmentButtonItemTuple, 
    backgroundBlurStyle: BlurStyle.BACKGROUND_THICK 
  }) 
  // 配置按钮组默认选中项 
  @State tabSelectedIndexes: number[] = [2] 
  @State singleSelectCapsuleSelectedIndexes: number[] = [1] 
 
  build() { 
    Row() { 
      Column() { 
        Column({ space: 25 }) { 
          SegmentButton({ 
            options: this.tabOptions, 
            selectedIndexes: $tabSelectedIndexes 
          }) 
          SegmentButton({ 
            options: this.singleSelectCapsuleOptions, 
            selectedIndexes: $singleSelectCapsuleSelectedIndexes 
          }) 
        } 
        .width('90%') 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
