metro服务未自动拷贝静态文件 导致生成的bundle无法加载目标图片,而 android和ios会自动拷贝目标图片。
执行npx react-native bundle-harmony --dev后
再次运行npm run start即可

针对您提出的HarmonyOS 鸿蒙Next RN项目中ImageBackground无法正确使用的问题,以下是一些可能的原因及解决方案:
- 图片路径问题:请确保ImageBackground所引用的图片路径正确,且图片文件存在于指定路径中。
- 图片格式支持:检查图片格式是否为ImageBackground组件所支持(如PNG、JPEG等)。不支持的格式可能导致图片无法显示。
- API版本兼容性:请确认您的HarmonyOS版本是否支持您正在使用的ImageBackground相关API。
- 组件设置冲突:检查是否有其他组件或样式设置覆盖了ImageBackground的显示。
- 资源文件位置:确保图片资源已正确放置在项目的resources文件夹中,并在代码中正确引用。
如果以上方法均无法解决问题,可能是由于其他未知因素导致。此时,您可以尝试联系官网客服,获取更专业的帮助。官网地址是:https://www.itying.com/category-93-b0.html 。
