HarmonyOS 鸿蒙Next的Text组件有类似安卓TextView中的android:lines的属性么

可以通过measure测量要显示文本和maxline文本对应的高度，对比两者高度，如果发现前者高度小于后者高度，就给前者文本末尾追加上’\n’，核心代码如下：

@State shorttitle: string = "这是一段文本";
titleWidth: number = 350;
MAX_LINES: number = 2;
fontSize: number = 16;

let titleSize: SizeOptions = measure.measureTextSize({
  textContent: this.shorttitle,
  constraintWidth: this.titleWidth,
  fontSize: this.fontSize
})
// 设置maxlines后文本的尺寸
let twoLineSize: SizeOptions = measure.measureTextSize({
  textContent: this.rawTitle,
  constraintWidth: this.titleWidth,
  fontSize: this.fontSize,
  maxLines: this.MAX_LINES
})
//文本未超过限制行数，不进行补齐处理
if ((titleSize.height as number) == (twoLineSize.height as number)) {
  return;
}
let clipTitle: string = this.shorttitle
//文本本身不满足最大行的高度，对文本进行补充
while ((titleSize.height as number) < (twoLineSize.height as number)) {
  clipTitle = clipTitle + '\n';
  titleSize = measure.measureTextSize({
    textContent: clipTitle + this.ellipsis,
    constraintWidth: this.titleWidth,
    fontSize: this.fontSize
  })
}
this.shorttitle = clipTitle;
