HarmonyOS 鸿蒙Next版本实战 - 溢彩美妆App（3）

按钮组

2个按钮在一行之内，第二个按钮背景色是透明的：

Row({space: 40}) {


    Button() {

      Text(<span class="hljs-string"><span class="hljs-string">'浏览全部'</span></span>)
        .fontSize(<span class="hljs-number"><span class="hljs-number">16</span></span>)

图片区

页面中部右侧是化妆品的图片集中展示。首先在pages目录下新建banner.ets源文件。

双卡片组

卡片组由2个图片拼成一组，加上圆角：

 Row() {


    Image($r(<span class="hljs-string"><span class="hljs-string">"app.media.bannner1"</span></span>))
      .width(<span class="hljs-number"><span class="hljs-number">267</span></span>)
      .height(<span class="hljs-number"><span class="hljs-number">274</span></span>)
      .objectFit(ImageFit.Contain)
      .borderRadius(<span class="hljs-number"><span class="hljs-number">24</span></span>)
      .margin(right: <span class="hljs-number"><span class="hljs-number">20</span></span>)

    Image($r(<span class="hljs-string"><span class="hljs-string">"app.media.banner2"</span></span>))
      .width(<span class="hljs-number"><span class="hljs-number">267</span></span>)
      .height(<span class="hljs-number"><span class="hljs-number">274</span></span>)
      .objectFit(ImageFit.Contain)
      .borderRadius(<span class="hljs-number"><span class="hljs-number">24</span></span>)

  } 
.padding(<span class="hljs-number"><span class="hljs-number">20</span></span>)

<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

横幅卡片

卡片组下方是一个相当于整个卡片组宽度的横幅卡片：

Image($r(“app.media.banner3”))
.width(555)
.height(274)
.objectFit(ImageFit.Contain)
.borderRadius(24)
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

完整组件源码和预览效果

将以上纯组件和预览用组件组合起来，banner.ets源文件整个页面的代码：

@Entry
@Component
export default struct Banner {


build() {


Column() {

  Row() {

    Image($r(<span class="hljs-string"><span class="hljs-string">"app.media.banner11"</span></span>))
      .width(<span class="hljs-number"><span class="hljs-number">210</span></span>)
      .height(<span class="hljs-number"><span class="hljs-number">222</span></span>)
      .objectFit(ImageFit.Contain)
      .borderRadius(<span class="hljs-number"><span class="hljs-number">24</span></span>)
      .margin({right: <span class="hljs-number"><span class="hljs-number">20</span></span>})

    Image($r(<span class="hljs-string"><span class="hljs-string">"app.media.banner22"</span></span>))
      .width(<span class="hljs-number"><span class="hljs-number">210</span></span>)
      .height(<span class="hljs-number"><span class="hljs-number">222</span></span>)
      .objectFit(ImageFit.Contain)
      .borderRadius(<span class="hljs-number"><span class="hljs-number">24</span></span>)

  }
  .padding(<span class="hljs-number"><span class="hljs-number">20</span></span>)

  Image($r(<span class="hljs-string"><span class="hljs-string">"app.media.bannerl3"</span></span>))
    .width(<span class="hljs-number"><span class="hljs-number">440</span></span>)
    .height(<span class="hljs-number"><span class="hljs-number">222</span></span>)
    .objectFit(ImageFit.Contain)
    .borderRadius(<span class="hljs-number"><span class="hljs-number">24</span></span>)

}

}
}
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

切换图片区的图片名称，以及查看在暗黑模式下的效果：

评价浮层

在图片区左下有一个用户评价的浮层。在pages目录下新建comment.ets源文件。

评价卡片

评价卡片包含文字和评分图片，其中评分图片使用ForEach进行循环渲染5次：

 Column() {


    Text(<span class="hljs-string"><span class="hljs-string">'小周'</span></span>)
      .fontSize(<span class="hljs-number"><span class="hljs-number">16</span></span>)
      .fontColor(<span class="hljs-string"><span class="hljs-string">'#26273C'</span></span>)
      .fontWeight(FontWeight.Bold)

    Text(<span class="hljs-string"><span class="hljs-string">'最好用的套装之一'</span></span>)
      .fontSize(<span class="hljs-number"><span class="hljs-number">14</span></span>)
      .fontColor(<span class="hljs-string"><span class="hljs-string">'#585C77'</span></span>)
      .fontWeight(FontWeight.Lighter)

    Row(space: <span class="hljs-number"><span class="hljs-number">8</span></span>) {
      ForEach([<span class="hljs-number"><span class="hljs-number">1</span></span>,<span class="hljs-number"><span class="hljs-number">2</span></span>,<span class="hljs-number"><span class="hljs-number">3</span></span>,<span class="hljs-number"><span class="hljs-number">4</span></span>,<span class="hljs-number"><span class="hljs-number">5</span></span>],   () =&gt; {
        Image($r(<span class="hljs-string"><span class="hljs-string">"app.media.star_cmt"</span></span>))
          .width(<span class="hljs-number"><span class="hljs-number">15</span></span>)
          .height(<span class="hljs-number"><span class="hljs-number">15</span></span>)
          .objectFit(ImageFit.Contain)
      })
    }
    .padding({top: <span class="hljs-number"><span class="hljs-number">10</span></span>})

  }
  .alignItems(HorizontalAlign.Start)
  .width(<span class="hljs-number"><span class="hljs-number">263</span></span>)
  .height(<span class="hljs-number"><span class="hljs-number">111</span></span>)
  .shadow({
    radius:<span class="hljs-number"><span class="hljs-number">15</span></span>,
    color: <span class="hljs-string"><span class="hljs-string">'#F8F9FC'</span></span>}
  )
  .backgroundColor(Color.White)
  .padding(<span class="hljs-number"><span class="hljs-number">20</span></span>)
  .margin(<span class="hljs-number"><span class="hljs-number">20</span></span>)
  .borderRadius(<span class="hljs-number"><span class="hljs-number">18</span></span>)

<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

因为卡片背景是白色，在正常模式下无法看到边界，切换到暗黑模式下进行预览：

36.png

评价头像

评价图片周围有边框，Image本身并不支持这样的边框，可以包装在Column容器中赋予均等的内边距即可：

Column() {
Image($r(“app.media.avatar_2”))
.width(56)
.height(56)
.borderRadius(8)
}
.backgroundColor(’#C4C4C4’)
.padding(5)
.borderRadius(8)
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

37.png

完整源码和预览效果

将以上卡片和头像组合起来，再讲头像的位置做一定程度的向左上偏移，comment.ets源文件整个页面的代码：

@Entry
@Component
export default struct Comment {
build() {


Stack() {

  Column() {

    Text(<span class="hljs-string"><span class="hljs-string">'小周'</span></span>)
      .fontSize(<span class="hljs-number"><span class="hljs-number">16</span></span>)
      .fontColor(<span class="hljs-string"><span class="hljs-string">'#26273C'</span></span>)
      .fontWeight(FontWeight.Bold)

    Text(<span class="hljs-string"><span class="hljs-string">'最好用的套装之一'</span></span>)
      .fontSize(<span class="hljs-number"><span class="hljs-number">14</span></span>)
      .fontColor(<span class="hljs-string"><span class="hljs-string">'#585C77'</span></span>)
      .fontWeight(FontWeight.Lighter)

    Row({space: <span class="hljs-number"><span class="hljs-number">8</span></span>}) {
      ForEach([<span class="hljs-number"><span class="hljs-number">1</span></span>,<span class="hljs-number"><span class="hljs-number">2</span></span>,<span class="hljs-number"><span class="hljs-number">3</span></span>,<span class="hljs-number"><span class="hljs-number">4</span></span>,<span class="hljs-number"><span class="hljs-number">5</span></span>], () =&gt; {
        Image($r(<span class="hljs-string"><span class="hljs-string">"app.media.star_cmt"</span></span>))
          .width(<span class="hljs-number"><span class="hljs-number">15</span></span>)
          .height(<span class="hljs-number"><span class="hljs-number">15</span></span>)
          .objectFit(ImageFit.Contain)
      })
    }
    .padding({top: <span class="hljs-number"><span class="hljs-number">10</span></span>})

  }
  .alignItems(HorizontalAlign.Start)
  .width(<span class="hljs-number"><span class="hljs-number">263</span></span>)
  .height(<span class="hljs-number"><span class="hljs-number">111</span></span>)
  .shadow({
    radius:<span class="hljs-number"><span class="hljs-number">15</span></span>,
    color: <span class="hljs-string"><span class="hljs-string">'#F8F9FC'</span></span>
  })
  .backgroundColor(Color.White)
  .padding({left: <span class="hljs-number"><span class="hljs-number">70</span></span>,top: <span class="hljs-number"><span class="hljs-number">20</span></span>})
  .margin(<span class="hljs-number"><span class="hljs-number">20</span></span>)
  .borderRadius(<span class="hljs-number"><span class="hljs-number">18</span></span>)

  Row() {
    Column() {
      Image($r(<span class="hljs-string"><span class="hljs-string">"app.media.avatar_2"</span></span>))
        .width(<span class="hljs-number"><span class="hljs-number">56</span></span>)
        .height(<span class="hljs-number"><span class="hljs-number">56</span></span>)
        .borderRadius(<span class="hljs-number"><span class="hljs-number">8</span></span>)
    }
    .backgroundColor(<span class="hljs-string"><span class="hljs-string">'#C4C4C4'</span></span>)
    .padding(<span class="hljs-number"><span class="hljs-number">5</span></span>)
    .borderRadius(<span class="hljs-number"><span class="hljs-number">8</span></span>)
    .alignItems(HorizontalAlign.Start)
  }
  .width(<span class="hljs-string"><span class="hljs-string">'100%'</span></span>)
  .offset({
    y: -<span class="hljs-number"><span class="hljs-number">30</span></span>
  })

}
.padding(<span class="hljs-number"><span class="hljs-number">20</span></span>)

}
}
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

首页的调整优化

将以上组件完整组合在一个Stack内，index.ets代码如下：

Stack() {


  Back()

  Column() {

    Nav()

    Row() {

      Theme()

      Banner()

    }

  }

}
.width(<span class="hljs-string"><span class="hljs-string">'100%'</span></span>)
.height(<span class="hljs-string"><span class="hljs-string">'100%'</span></span>)

<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

39.png

看起来导航、主题文字区、图片组都偏大，需要针对性调整。

各子组件的调整，不再赘述，请同学们自行调整。

首页调整

把首页进行相应尺寸调整，另外加上评价浮层及偏移，index.ets代码如下：


import Back from ‘./back.ets’
import Nav from ‘./nav.ets’
import Theme from ‘./theme.ets’
import Banner from ‘./banner.ets’
import Comment from ‘./comment.ets’


@Entry
@Component
struct Index {
build() {
Stack() {


  Back()

  Column() {

    Nav()

    Row() {

      Theme()

      Banner()

    }
  }
  .height(<span class="hljs-string"><span class="hljs-string">'100%'</span></span>)

  Column() {

    Blank()

    Comment()

  }
  .height(<span class="hljs-string"><span class="hljs-string">'100%'</span></span>)
  .offset({
    x: <span class="hljs-number"><span class="hljs-number">100</span></span>
  })


}
.width(<span class="hljs-string"><span class="hljs-string">'100%'</span></span>)
.height(<span class="hljs-string"><span class="hljs-string">'100%'</span></span>)

}
}
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

预览效果

调整优化后的首页预览：

暗黑模式下的效果如下：

您可以根据本帖开始的设计效果，自行更改适配的字体颜色。

总结

NEXT更适合App开发，配合最新的DevEco Studio 5.0，即使您手头没有设备，也可以进行相对完善的UI开发大部分工作。
