Slider组件的showTips属性，如果填入文件较多，显示不全，例如.showTips(true, "2018.01.03 \n 10:10:10")

请参考以下自定义slider自带的tips样式：

const BLOCK_DEFAULT_BORDER_WIDTH = 4;
@Entry
@Component
struct SliderIndex {
  @State isTipShow: boolean = false;
  @State tipsOffset: number = 0;
  private slideHeight: number = 300;
  private blockSize: number = 20;
  private tipHeight: number = 40;
  private hideTipTask?: number;

  private showTip(value: number) {
    this.isTipShow = true
    let percent = Number((value / 100).toFixed(2));
    this.tipsOffset = (this.slideHeight - this.blockSize - BLOCK_DEFAULT_BORDER_WIDTH * 2) * percent -
      (this.tipHeight / 2 - (this.blockSize / 2 + BLOCK_DEFAULT_BORDER_WIDTH));
  }

  private hideTip() {
    clearTimeout(this.hideTipTask)
    this.hideTipTask = setTimeout(() => {
      this.isTipShow = false
    }, 3000)
  }

  build() {
    Row() {
      Slider({ direction: Axis.Vertical, })
        .height(this.slideHeight)
        .selectedColor(Color.Green)
        .trackColor('#5a5a5a')
        .trackThickness(10)
        .blockSize({ width: this.blockSize, height: this.blockSize })
        .selectedColor('#FF6103')
        .onChange((value: number, mode: SliderChangeMode) => {
          switch (mode) {
            case SliderChangeMode.Moving:
            case SliderChangeMode.Click:
              this.showTip(value);
              break;
            case SliderChangeMode.End:
              this.hideTip();
              break;
          }
        })
      if (this.isTipShow) {
        Text("i am tip!")
          .fontSize(12)
          .height(this.tipHeight)
          .offset({ y: this.tipsOffset })
          .fontColor(Color.White)
          .backgroundColor("#66000000")
          .padding(10)
          .borderRadius(5)
          .hitTestBehavior(HitTestMode.Transparent)
      }
    }.alignItems(VerticalAlign.Top).padding(20).height('100%').width('100%')
  }
}
