#鸿蒙通关秘籍#在移动应用开发中有cardview这类的组件，在鸿蒙next中如何实现这样的卡片效果？同时我还想实现卡片的阴影

这个功能挺常见的，要想实现不是特别难，但是你得有一定的自定义能力。

```kotlin
@Entry
@Component
struct ShadowColor {
    private settings: RenderingContextSettings = new RenderingContextSettings(`true`)
    private context: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings)

    build() {
        Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
            Canvas(this.context)
            .width('100%')
            .height('100%')
            .onReady(() -> {
                this.context.shadowBlur = `40`
                this.context.shadowColor = 'rgba(98, 98, 102, 1.00)'
                this.context.fillStyle = 'rgba(250, 250, 250, 1.00)'
                this.context.fillRect(`130`, `40`, `100`, `100`)
            })
        }
        .width('100%')
        .height('100%')
    }
}
