1、HarmonyOS List+Swipe+web滑动冲突？
在List中嵌套一个横向滑动的swipe，swipe嵌套一个web，此时设置手势优先的时，web无法和list进行联动交互
题原因可能是List组件嵌套Web组件产生了滑动冲突，这里可以使用触摸测试控制来规避此种情况：.hitTestBehavior(HitTestMode.Block)
参考文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/arkts-gesture-events-multi-level-gesture-V5
2、HarmonyOS Webview如何实现下拉刷新效果？
可以使用pulltorefresh实现下拉刷新。参考链接如下：https://ohpm.openharmony.cn/#/cn/detail/@ohos%2Fpulltorefresh
3、通过Command line进行编译，如果发生错误，如何获取到错误信息，或者能获取到编译成功状态。
- 用hvigor进行编译的时候，可用加上各种命令，显示相关日志信息；
- -d（设置hvigor的日志级别为debug）
- –stacktrace（hvigor默认使能关闭打印所有异常的堆栈信息，如需开启在命令行后添加该选项）
- https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/ide-hvigor-commandline-V5
- 执行命令编译时只会有返回码的：
- 构建成功：code 0
- 构建失败：code 1
- 基于不同平台采用对应方式获取该返回码就行。
4、HarmonyOS 普通对象怎么监听组件生命周期？
可以参考这个：https://gitee.com/openharmony/docs/blob/7ad8e708cebd3e4a43979e97de160da9c0533316/zh-cn/application-dev/reference/apis/js-apis-arkui-observer.md

5、HarmonyOS 设备指纹应用市场的上架SDK需要满足的条件？
需要在应用市场的上架SDK
1、IDE版本需要canary4sp1及以上版本
2、签名证书的帐号和上架SDK的帐号使用企业账号AGC申请发布证书，IDE增加签名指导：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/ide-publish-app-V5
