HarmonyOS List item高度固定，宽度随内容长短不一，如何实现？

@Entry  
@Component  
struct ListExample {  
  private arr: string[] = ['测试1111', '测试', '测试0', '测试112222']  
  
  build() {  
    Column() {  
      Row() {  
        ForEach(this.arr, (item: string) => {  
            Text(item)  
              .height(50).fontSize(16)  
              .textAlign(TextAlign.Center).borderRadius(10).backgroundColor(0xFFFFFF)  
        }, (item: string) => item)  
      }.width('100%')  
      .height('100%')  
      .backgroundColor(Color.Pink)  
      .justifyContent(FlexAlign.SpaceEvenly)  
      .flexGrow(1).flexShrink(0)  
    }  
    .width('100%')  
    .height('100%')  
    .backgroundColor(0xDCDCDC)  
    .padding({ top: 5 })  
  }  
}
