#鸿蒙通关秘籍#如何在HarmonyOS中实现径向渐变的应用？

为实现径向渐变效果，在HarmonyOS使用radialGradient接口。实现步骤如下：

@Entry
@Component
struct radialGradientDemo {
  build() {
    Grid() {
      GridItem() {
        Column() {
          Text('center: 50')
            .fontSize(15)
        }
        .width(100)
        .height(100)
        .justifyContent(FlexAlign.Center)
        .borderRadius(10)
        .radialGradient({
          center: [50, 50],
          radius: 100,
          repeating: true,
          colors: [
            [0xf56c6c, 0],
            [0xffffff, 0.125],
            [0x409EFF, 0.25]
          ]
        })
      }

      GridItem() {
        Column() {
          Text('center: 0')
            .fontSize(15)
        }
        .width(100)
        .height(100)
        .justifyContent(FlexAlign.Center)
        .borderRadius(10)
        .radialGradient({
          center: [0, 0],
          radius: 100,
          repeating: true,
          colors: [
            [0xf56c6c, 0],
            [0xffffff, 0.125],
            [0x409EFF, 0.25]
          ]
        })
      }

      GridItem() {
        Column() {
          Text('repeat: true')
            .fontSize(15)
        }
        .width(100)
        .height(100)
        .justifyContent(FlexAlign.Center)
        .borderRadius(10)
        .radialGradient({
          center: [50, 50],
          radius: 100,
          repeating: true,
          colors: [
            [0xf56c6c, 0],
            [0xffffff, 0.125],
            [0x409EFF, 0.25]
          ]
        })
      }

      GridItem() {
        Column() {
          Text('repeat: false')
            .fontSize(15)
        }
        .width(100)
        .height(100)
        .justifyContent(FlexAlign.Center)
        .borderRadius(10)
        .radialGradient({
          center: [50, 50],
          radius: 100,
          repeating: false,
          colors: [
            [0xf56c6c, 0],
            [0xffffff, 0.125],
            [0x409EFF, 0.25]
          ]
        })
      }
    }
    .columnsGap(10)
    .rowsGap(10)
    .columnsTemplate('1fr 1fr')
    .rowsTemplate('1fr 1fr 1fr')
    .width('100%')
    .height('100%')
  }
}
