Epidemic Service Assistant 疫情服务助手卡片

介绍

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
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

项目结构

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。

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
