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。

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

  
 
 
 
    
   
  
  
  
  1. //设置跳转事件 
    2. 
   
  
  
  
  2. componentProvider.setIntentAgent(viewId, getIntentAgent(actionKey)); 
    3.

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

    2. 
   
  
  
  
  2. //获取位置 
    3. 
   
  
  
  
  3. regionText = (Text) findComponentById(ResourceTable.Id_text_main_region); 
    4. 
   
  
  
  
  4. new LocationHelper().getMyLocation(getContext(), currentRegion -> { 
    5. 
   
  
  
  
  5.     getUITaskDispatcher().asyncDispatch(() -> { 
    6. 
   
  
  
  
  6.         regionText.setText(currentRegion); 
    7. 
   
  
  
  
  7.     }); 
    8. 
   
  
  
  
  8. }); 
    9.

4.二维码生成的问题

使用到了QRCodeUtil工具类，

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
