自适应缩放布局如何实现

@Entry
@Component
struct layoutWeightExample {
  build() {
    Column() {
      Text('1:2:3').width('100%')
      Row() {
        Column() {
          Text('layoutWeight(1)')
            .textAlign(TextAlign.Center)
        }.layoutWeight(1).backgroundColor(0xF5DEB3).height('100%')

        Column() {
          Text('layoutWeight(2)')
            .textAlign(TextAlign.Center)
        }.layoutWeight(2).backgroundColor(0xD2B48C).height('100%')

        Column() {
          Text('layoutWeight(3)')
            .textAlign(TextAlign.Center)
        }.layoutWeight(3).backgroundColor(0xF5DEB3).height('100%')

      }.backgroundColor(0xffd306).height('30%')

      Text('2:5:3').width('100%')
      Row() {
        Column() {
          Text('layoutWeight(2)')
            .textAlign(TextAlign.Center)
        }.layoutWeight(2).backgroundColor(0xF5DEB3).height('100%')

        Column() {
          Text('layoutWeight(5)')
            .textAlign(TextAlign.Center)
        }.layoutWeight(5).backgroundColor(0xD2B48C).height('100%')

        Column() {
          Text('layoutWeight(3)')
            .textAlign(TextAlign.Center)
        }.layoutWeight(3).backgroundColor(0xF5DEB3).height('100%')
      }.backgroundColor(0xffd306).height('30%')
    }
  }
