鸿蒙疫情助手卡片，太方便了...

前段时间国内的新冠疫情又出现了一些波动，公司也要求每天上报健康码和行程码，就想着能不能用服务卡片做一个，于是就开始行动了。

想着大体可以分成 2 步走，需要先设计 UI，然后对接相关的接口，不过对接接口要麻烦一些，需要有相关的开放接口，目前还没实现。

搭建环境

安装 DevEco Studio，详情请参考 DevEco Studio 下载：

https://developer.harmonyos.com/cn/develop/deveco-studio

设置 DevEco Studio 开发环境，DevEco Studio 开发环境需要依赖于网络环境，需要连接上网络才能确保工具的正常使用。

可以根据如下两种情况来配置开发环境：

• • 
    
• 如果可以直接访问 Internet，只需进行下载 HarmonyOS SDK 操作。
• 如果网络不能直接访问 Internet，需要通过代理服务器才可以访问，请参考配置开发环境。
  •

实现步骤

①编写界面

ability_main.xml 主界面：这个界面会显示获取到城市，以及地区的风险等级，然后就是安康码和行程卡的入口。

itinerary_card_slice.xml 行程卡界面：行程卡的显示界面，上半部分是通过短信验证码获取行程信息，下半部分是显示获取到的行程信息。

health_code_slice 安康码界面：安康码的显示界面，上半部部分显示当前所在城市，下半部分显示获取的安康码信息，然后是一个行程卡的入口。

form_image_with_info_date_card_2_2.xml 2x2 的卡片界面：form_image_with_info_date_card_2_4.xml 2x4 的卡片界面：

②编写启动应用代码

MainAbility.java：

问题总结

①解决页面布局问题，模拟器看到的效果和真机显示不完整存在差异：

//卡片布局中 ohos:remote=“true” 一定要加

②解决一个卡片，不同功能区跳转到不同的 Slice 问题：

//设置跳转事件componentProvider.setIntentAgent(viewId, getIntentAgent(actionKey));

③解决获取位置问题：

使用LocationHelper,HttpUtils,GsonUtils工具类，获取经纬度后还需要逆地理编码
//获取位置
regionText = (Text) findComponentById(ResourceTable.Id_text_main_region);
new LocationHelper().getMyLocation(getContext(), currentRegion -> {
    getUITaskDispatcher().asyncDispatch(() -> {
        regionText.setText(currentRegion);
    });
});

④二维码生成的问题，使用到了 QRCodeUtil 工具类，官方指导：

https://developer.huawei.com/consumer/cn/codelabsPortal/carddetails/HarmonyOS-QRCode

⑤待解决安康码，行程卡相关接口调用问题，需要找到相关的开放接口。
