参考如下代码

import { drawing } from '@kit.ArkGraphics2D';
import { display } from '@kit.ArkUI';

@Entry
@Component
struct Index10 {
  @State textStr1: string = '文案1';
  @State textStr3: string = '文案3';
  @State textStr3Width:number = 0
  @State textStr1Width:number = 0
  screenWidthPx:number = 0
  screenHeightPx:number = 0

  aboutToAppear(): void {

    const font = new drawing.Font()
    font.setSize(12)
    this.textStr1Width = font.measureText(this.textStr1, drawing.TextEncoding.TEXT_ENCODING_UTF8)
    this.textStr3Width = font.measureText(this.textStr3, drawing.TextEncoding.TEXT_ENCODING_UTF8)
    let displaydef = display.getDefaultDisplaySync()
    this.screenWidthPx = displaydef.width
    this.screenHeightPx = displaydef.height
  }

  build() {
    Column() {
      Row(){
        Text(this.textStr1)
          .fontSize(12)
          .width(this.textStr1Width)
        Text('22222222222222222222222222222222222222222222222222222222222')
          .width(px2vp(this.screenWidthPx)-this.textStr1Width-this.textStr3Width)
          .fontSize(12)
          .maxLines(1)
          .textOverflow({overflow:TextOverflow.Ellipsis})
          .ellipsisMode(EllipsisMode.END)
          .wordBreak(WordBreak.BREAK_ALL)

        Text(this.textStr3)
          .fontSize(12)
          .width(this.textStr3Width)
      }
      .width('100%')
    }
  }
}
