HarmonyOS Select组件参数options参数动态获取，没法正常绘制数据内容

可以定义一个Array<SelectOption>类型的数据，网数组中push类型为SelectOption的值，将数组作为Select的参数。

参考demo：

class Data{
  value: string
  icon: Resource

  constructor(value: string, icon: Resource) {
    this.value= value;
    this.icon= icon;
  }
}

// xxx.ets
@Entry
@Component
struct SelectExample {
  @State text: string = "下拉菜单展示"
  @State index: number = 2
  @State space: number = 8
  @State arrowPosition: ArrowPosition = ArrowPosition.END
  @State arr: Array<SelectOption> = [new Data('数据0',$r("app.media.startIcon"))];
  private  count:number =0;

  build() {
    Column({space: 20}) {
      Button('添加数据').onClick((event: ClickEvent) => {
        this.count++;
        this.arr.push(new Data('数据'+this.count,$r("app.media.startIcon")))
      })
      Select(this.arr)
        .selected(this.index)
        .value(this.text)
        .font({ size: 16, weight: 500 })
        .fontColor('#182431')
        .selectedOptionFont({ size: 16, weight: 400 })
        .optionFont({ size: 16, weight: 400 })
        .space(this.space)
        .arrowPosition(this.arrowPosition)
        .menuAlign(MenuAlignType.START, {dx:0, dy:0})
        .optionWidth(200)
        .optionHeight(300)
        .onSelect((index:number, text?: string | undefined)=>{
          console.info('Select:' + index)
          this.index = index;
          if(text){
            this.text = text;
          }
        })

    }.width('100%')
  }
}
