这是 HarmonyOS SDK 中 sys.media 的系统资源库（System Resource）的一部分。

你看到的：

media: {
    ohos_app_icon: 130023425,
    ai_recognize: 130023427,
    huawei_id_logo_red: 130023436,
    huawei_id_logo_white: 130023437,
    ...
}

本质上是系统资源ID映射表，类似 Android 的：

android.R.drawable.ic_menu_camera

只不过 HarmonyOS 最终编译后显示成数字资源ID，所以直接点进去只能看到：

130023425
130023427
130023436

而看不到实际图片。

如何查看这些图标？

方法1：在代码中直接使用

例如：

Image($r('sys.media.ai_recognize'))
  .width(48)
  .height(48)

或者：

Image($r('sys.media.huawei_id_logo_red'))

运行到真机或模拟器后即可看到。

方法2：使用资源预览

DevEco Studio 6.x 中：

Resource Manager
↓
sys.media

部分版本支持资源预览。

但目前很多系统资源：

sys.media
sys.color
sys.float

只展示资源名，不展示图片内容。

这是 IDE 的限制。

方法3：查看 SDK 系统资源包

Windows 默认路径：

DevEcoStudio\sdk\default\openharmony\ets\api\@ohos.arkui.drawable.d.ts

或者：

DevEcoStudio\sdk\default\openharmony\previewer\resources

不同版本位置略有不同。

有些 SVG 资源实际上存放在：

openharmony\ets\build-tools\ace-loader\resources

中。

如何获取全部 sys.media 图标列表？

官方目前没有提供完整图标图库页面。

比较方便的方法：

方法1

在项目中输入：

$r('sys.media.

然后：

Ctrl + Space

IDE 会自动列出所有可用资源。

例如：

sys.media.ohos_app_icon
sys.media.ic_back
sys.media.ic_public_cancel
sys.media.ic_public_add
sys.media.ic_public_search
...

方法2（推荐）

直接查看 SDK 中生成的：

sys.d.ts

或：

resource.d.ts

文件。

搜索：

declare namespace media

能看到全部资源名称。

如果想批量查看所有图标

可以写一个简单页面：

@Entry
@Component
struct Demo {
  private icons: string[] = [
    'ai_recognize',
    'AI_circle_viewfinder',
    'AI_keyboard',
    'AI_lightbulb_max'
  ]

  build() {
    List() {
      ForEach(this.icons, (item:string) => {
        ListItem() {
          Row() {
            Image($r(`sys.media.${item}`))
              .width(40)
              .height(40)

            Text(item)
              .margin({ left: 10 })
          }
        }
      })
    }
  }
}

这样运行后就能把图标实际渲染出来。

补充一点：

你列出来的：

ai_recognize
AI_circle_viewfinder
AI_keyboard
AI_lightbulb_max

这些是 HarmonyOS 6.1 新增的 AI 相关系统图标，主要给系统 AI 服务、小艺、AI搜索等场景使用，并不是完整图标库。

真正的系统图标数量实际上有几百个，包括：

返回
搜索
删除
编辑
分享
更多
相机
相册
电话
消息
下载
上传
设置

等公共图标资源。

楼主，帮你找了一圈sdk里面，这些图片放在如下图：
第一批：DevEco Studio\sdk\default\openharmony\previewer\common\resources\resources\base\media

第二批：DevEco Studio\sdk\default\hms\previewer\resources\resources\resources\base\media

vueper 3楼

希望HarmonyOS能继续推出更多实用的功能，满足用户的不同需求。

sys.media框架内置图标库包含多种系统媒体控制图标，如：播放（play）、暂停（pause）、停止（stop）、上一首（previous）、下一首（next）、音量加（volume+）、音量减（volume-）、静音（mute）、麦克风（mic）、扬声器（speaker）、蓝牙（bluetooth）、投屏（cast）等。具体图标名称及资源ID参见官方API文档中MediaControlPanel组件的系统图标枚举。

HarmonyOS Next 中 sys.media 是系统提供的媒体资源集合，你看到的数字是图标对应的资源 ID。内置图标包括 ohos_app_icon（默认华为应用图标）、ai_recognize、AI_circle_viewfinder、AI_keyboard、AI_lightbulb_max 及多种华为 ID 相关 Logo（如 huawei_id_logo_red、huawei_id_logo_white 等）。使用时可写成 $r('sys.media.图标名')，在 DevEco Studio 中输入 $r('sys.media. 会自动提示全部可用图标名称并展示预览，无需关心数字 ID。
