我正在开发Tizen Native Wearable App。
我想更改进度条的颜色，所以我按照以下链接进行操作：
我知道为了改变Tizen中任何小部件的颜色，我需要使用“主题”，但我无法让它工作。 这就是我所做的：
在 app_main.c 中，我有：
static bool _on_create_cb(void *user_data)
{
uib_app_manager_get_instance()->initialize();
char resource_path[PATH_MAX];
app_get_resource("edje/progressbar_custom.edj", resource_path, (int)PATH_MAX);
elm_theme_extension_add(NULL, resource_path);
return true;
}
在 res 文件夹中，我创建了一个文件夹 edje ，然后在 res / edje 中我创建了一个文件 progressbar_custom.edc < / EM> progressbar_custom.edc 的内容是第一个链接中给出的答案。
然后在我的进度条对象中设置样式：
...
Evas_Object* pb;
pb = elm_progressbar_add(parent);
elm_object_style_set(pb, "custom_progress");
...
当我启动应用时，进度条不会显示。 我想问题是 progressbar_custom.edc 的内容，因为我认为它来自移动设备，而不是可穿戴设备。每个教程都说要复制“默认样式”的内容，但我不知道这个“默认样式”在哪里！
任何帮助都是赞成的，谢谢！
答案 0 :(得分：0)
我认为edc文件中的EDJE语法或部件名称在当前的可穿戴设备中无法使用。
data.item表示从edje外部提供的一些数据。
而blar_vg_blar意味着efl矢量图形API在那里画了一些东西。
但是矢量图形API不是tizen wearable的版本（2.3.1）。
基本上，小学的EDJE主题与基本小部件代码超级纠缠。基本小部件代码在EDC文件中使用硬编码信号和部件名称。
所以小学的主题并不意味着像css这样的另一个主题。
它具有查看和事件的逻辑以及用于查看的一些控制器和数据。
如果你想创建新主题，你可以再次实现在默认主题中实现的所有内容。
最简单的方法是复制原始文件并进行编辑。因此，您必须检查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操作系统都在2.3.1之下。
所以你应该使用tizen 2.3.1可穿戴的个人资料进行主题匹配。
this是tizen 2.3.1可穿戴资料的基本主题。 它在真实设备中并不相同，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是相同的关系。
无论如何，你可以在tizen 2.3.1 wearable中引用this默认进度条主题。
我在EDC的第一组中使用修改后的默认样式做了一些简单的例子。
