我认为您的 edc 文件中的 EDJE 语法或部件名称在当前的可穿戴 tizen 中不可用。
data.item表示某些数据是从 edje 外部提供的。并且blar_vg_blar意味着efl矢量图形API在其中绘制了一些东西。但矢量图形 API 不在 tizen 可穿戴设备 (2.3.1) 版本中。
基本上，Elementary 的 EDJE 主题与基本小部件代码超级纠缠在一起。基本小部件代码使用 EDC 文件中的硬编码信号和部件名称。
所以基本的主题并不意味着像css. 它具有用于查看和事件的逻辑以及一些用于查看的控制器和数据。
如果你想制作新主题，你可以再次实现在默认主题中实现的所有内容。
最好的简单方法是复制原始文件并进行编辑。所以你必须检查你的目标版本以复制正确的主题。
目前，三星设备中的每个可穿戴 tizen 操作系统都低于 2.3.1。
所以你应该使主题与 tizen 2.3.1 可穿戴配置文件匹配。
这是 tizen 2.3.1 可穿戴配置文件的基本主题。它在真实设备中不一样，因为真实设备可以具有与原始配置文件不同的主题。它与 google 的 android 主题和其他供应商主题的关系相同。
无论如何，您可以参考这是 tizen 2.3.1 可穿戴设备中的默认进度条主题。
我在 EDC 的第一组中用修改的默认样式做了一些简单的例子。
