背景：
前几篇学习了元服务，后面几期就让我们开发简单的元服务吧，里面丰富的内容大家自己加，本期案例 仅供参考
先上本期效果图 ，里面图片自行替换
效果图1代码案例如下：
import { authentication } from '@kit.AccountKit';
import { BusinessError } from '@kit.BasicServicesKit';

.fontSize(18)
.fontColor(Color.Black)
Text('查看更多>')
.fontSize(15)
.fontColor(Color.Black)
}.justifyContent(FlexAlign.SpaceBetween).width('100%').padding(10).onClick(() => {
})
