HarmonyOS 鸿蒙Next 测试运行 界面空白 是什么原因啊 代码参考：鸿蒙BLE蓝牙通信开发总结

布局文件是自己简单写的一个布局：

楼主你好，给子组件的宽高赋值就可以显示了

好的，谢谢！我试一下，

基本信息

这是我的代码主题：

<div>
    <p>这是一段普通的文本。</p>
    <p>这是另一段文本。</p>
    <img src="" alt="这是一个空链接的图片">
</div>

布局有问题，所有的控件高度由match_parent改成match_content，使用Text，Button类组件时开发时先添加占位字符看看效果

这个日志可以发个带颜色那种的吗？一般红色的是问题所在

好的！麻烦大神帮忙看一下。。。。，

我没看明白，靠别的大神了，

好吧！辛苦了，

欢迎开发小伙伴们进来帮帮楼主

HarmonyOS 鸿蒙Next测试运行时出现界面空白的情况，可能由以下几种原因引起：

  1. 系统资源加载异常：在测试过程中，系统可能因为资源文件加载失败或损坏，导致界面无法正常显示。这可能是由于测试环境的配置问题，或者是系统文件在更新过程中被破坏。

  2. UI框架初始化失败：鸿蒙系统的UI框架负责界面的渲染和显示。如果框架在初始化过程中遇到问题，如内存不足、依赖服务未启动等，都可能导致界面空白。

  3. 权限或安全策略限制：在测试环境中，可能由于权限设置不当或安全策略过于严格，导致系统无法访问必要的资源或执行必要的操作，从而影响界面的正常显示。

  4. 软件兼容性问题：如果测试的应用或服务与鸿蒙系统的当前版本不兼容，也可能导致界面显示异常。

  5. 硬件或驱动问题：在某些情况下，硬件故障或驱动程序问题也可能影响系统的正常显示功能。

针对这些问题，可以尝试重新配置测试环境、检查系统日志以定位问题根源，并确保所有组件和服务的版本兼容性。如果问题依旧没法解决请联系官网客服，官网地址是 https://www.itying.com/category-93-b0.html 。
