+# floating_ui_plugin
+
+该目录是一个本地 Flutter 插件包，当前在项目中主要承担「悬浮 UI」相关的原生能力：
+
+- Android：翻译悬浮窗（系统悬浮窗 / overlay window）+ 录音悬浮条（计时/暂停/关闭）+ 悬浮窗权限检查/跳转。
+- iOS：为系统画中画（PiP）提供可渲染的原生内容 View，并支持动态更新翻译文本。
+
+> 说明：Flutter 包名为 floating_ui_plugin（见本插件 pubspec.yaml），主工程通过 path 依赖引用本目录。
+
+## 主要能力
+
+### 1) Android 翻译悬浮窗（Translation Floating Window）
+
+- 通道：`MethodChannel('floating_window')`
+- 原理：Flutter 调用通道方法 → Android 启动/更新 `FloatingWindowService` → service 通过系统 WindowManager 显示 overlay view。
+- 交互回传：service 会反向调用同一通道，把状态/点击/关闭事件回传给 Flutter。
+
+支持的方法（Flutter → Android）：
+- `enableFloatingWindow`：启动悬浮窗服务（如果已在运行，相当于确保存在）。
+- `disableFloatingWindow`：停止悬浮窗服务。
+- `showFloatingWindow`：显示悬浮窗（当前实现等价于启动服务）。
+- `hideFloatingWindow`：隐藏悬浮窗（stopSelf）。
+- `updateContent(Map)`：更新展示内容。
+- `setPosition({x,y})`：设置悬浮窗位置。
+
+回传的方法（Android → Flutter）：
+- `onFloatingWindowStateChanged({state})`：`hidden|minimized|expanded`
+- `onFloatingWindowClosed()`：用户关闭。
+- `onFloatingWindowClicked()`：用户点击语言区域（service 内部会 bringAppToFront）。
+
+数据协议（updateContent）：
+- `sourceText` / `translatedText`
+- `sourceLanguage` / `targetLanguage`
+- `timestamp`（毫秒时间戳）
+- `isIntermediate`（是否中间态）
+
+对应实现：
+- Android 插件入口：[NativePlugin.kt](file:///Users/liuxiamin/work/flutter_projects/deep_voice/local_plugins/floating_ui_plugin/android/src/main/kotlin/com/example/native_plugin/NativePlugin.kt)
+- 悬浮窗服务：[FloatingWindowService.kt](file:///Users/liuxiamin/work/flutter_projects/deep_voice/local_plugins/floating_ui_plugin/android/src/main/kotlin/com/example/native_plugin/FloatingWindowService.kt)
+
+### 2) Android 悬浮窗权限（Overlay Permission）
+
+- 通道：`MethodChannel('overlay_permission')`
+- 方法：
+  - `hasOverlayPermission`：是否具备 SYSTEM_ALERT_WINDOW
+  - `requestOverlayPermission`：跳转系统页面申请
+
+对应实现：[NativePlugin.kt](file:///Users/liuxiamin/work/flutter_projects/deep_voice/local_plugins/floating_ui_plugin/android/src/main/kotlin/com/example/native_plugin/NativePlugin.kt)
+
+### 3) Android 录音悬浮条（Recording Floating Bar）
+
+- 通道：`MethodChannel('native_plugin')`
+- 原理：Flutter 下发 show/update/hide → Android 启动/更新 `RecordingFloatingService` → service 以 overlay 方式显示一个小型悬浮条。
+
+支持的方法（Flutter → Android）：
+- `showRecordingFloatingBar({duration, recordingType, isPaused})`
+- `updateRecordingFloatingBar({duration, recordingType, isPaused})`
+- `hideRecordingFloatingBar()`
+
+用户操作回传（Android → Flutter）：
+- 事件通道：`EventChannel('native_plugin/recording_floating_actions')`
+- action 字符串：
+  - `togglePause`：点击暂停/继续
+  - `openMeetingRecord`：点击中间区域，拉起 App 并打开录音页
+  - `closeFloatingBar`：关闭悬浮条
+
+对应实现：
+- 服务：[RecordingFloatingService.kt](file:///Users/liuxiamin/work/flutter_projects/deep_voice/local_plugins/floating_ui_plugin/android/src/main/kotlin/com/example/native_plugin/RecordingFloatingService.kt)
+- 事件桥接：[NativePlugin.emitRecordingFloatingAction](file:///Users/liuxiamin/work/flutter_projects/deep_voice/local_plugins/floating_ui_plugin/android/src/main/kotlin/com/example/native_plugin/NativePlugin.kt#L26-L39)
+
+## iOS：PiP 内容 View（Picture-in-Picture Content View）
+
+- 通道：`MethodChannel('native_plugin')`
+- 目标：创建一个用于 PiP 渲染的原生 `UIView`（`PlayerView`），并支持后续更新显示内容。
+
+支持的方法：
+- `createPipContentView()`：返回一个 `viewId`（本质是 PlayerView 的指针值）。
+- `updatePipContentView({viewId?, lang, cn, en})`：更新内容。
+- `disposePipContentView(viewId)`：释放。
+
+对应实现：
+- 插件入口：[NativePlugin.swift](file:///Users/liuxiamin/work/flutter_projects/deep_voice/local_plugins/floating_ui_plugin/ios/Classes/NativePlugin.swift)
+- 具体 UI：[PlayerView.swift](file:///Users/liuxiamin/work/flutter_projects/deep_voice/local_plugins/floating_ui_plugin/ios/Classes/PlayerView.swift)
+
+## 在主工程中的调用链路（现状）
+
+### Android：翻译悬浮窗
+
+- 入口：翻译页控制器 [TranslationController](file:///Users/liuxiamin/work/flutter_projects/deep_voice/lib/modules/translation/controllers/translation_controller.dart)
+  - `toggleFloatingWindow()` → `_enableFloatingWindow()`
+- 管理器：[FloatingWindowManager](file:///Users/liuxiamin/work/flutter_projects/deep_voice/lib/core/services/floating_window_manager.dart)
+  - `enableFloatingWindow()`：先通过 [OverlayPermissionUtil](file:///Users/liuxiamin/work/flutter_projects/deep_voice/lib/core/utils/overlay_permission_util.dart) 请求权限，再调用 `TranslationFloatingWindowApi.enable()`
+  - `_setupMethodCallHandler()`：接收 `onFloatingWindowStateChanged/onFloatingWindowClicked/onFloatingWindowClosed` 并更新状态/路由跳转
+- 内容更新：`TranslationController._updateFloatingWindowWithTranslation()` → `FloatingWindowManager.updateFloatingWindowContent()` → `updateContent(Map)`
+
+### Android：录音悬浮条
+
+- 入口：会议录音控制器 [MeetingRecordController](file:///Users/liuxiamin/work/flutter_projects/deep_voice/lib/modules/meeting/controllers/meeting_record_controller.dart)
+  - `showBackgroundRecordingIndicator()` → `_startAndroidRecordingFloatingBar()` → `NativePlugin.showRecordingFloatingBar()`
+  - 定时器每秒 `updateRecordingFloatingBar()` 更新 duration/isPaused
+  - `_setupRecordingFloatingBarActionListener()` 监听 `recordingFloatingActionStream` 并处理 `togglePause/openMeetingRecord/closeFloatingBar`
+
+### iOS：翻译悬浮显示（PiP）
+
+- 入口同样在 [TranslationController](file:///Users/liuxiamin/work/flutter_projects/deep_voice/lib/modules/translation/controllers/translation_controller.dart)
+  - `_startPip()`：`NativePlugin.createPipContentView()` → 将 viewId 传给第三方 PiP 组件的 `PipOptions.contentView`
+  - `_updateFloatingWindowWithTranslation()`：`NativePlugin.updatePipContentView({viewId, cn, en, lang})`
+
+## 权限与 Manifest
+
+- Android 需要：`android.permission.SYSTEM_ALERT_WINDOW`
+- 本插件自带 AndroidManifest 声明（包含两项 service）：
+  - [android/src/main/AndroidManifest.xml](file:///Users/liuxiamin/work/flutter_projects/deep_voice/local_plugins/floating_ui_plugin/android/src/main/AndroidManifest.xml)
+
+## 平台差异与注意事项
+
+- Android 与 iOS 的“悬浮显示”实现不同：Android 用系统悬浮窗；iOS 走系统 PiP。
+- `createPipContentView/updatePipContentView/disposePipContentView` 仅 iOS 实现；Android 侧没有实现这些 method，请务必用 `Platform.isIOS` 保护调用。
+- `floating_window` / `overlay_permission` / `native_plugin/recording_floating_actions` 都是固定通道名，避免在其他地方重复注册同名通道。
+- 工程 `android/app/src/main/kotlin/com/saitong/voitrans/` 下存在同名通道的旧实现文件（未在 MainActivity 注册），当前实际走的是本插件实现；如后续要启用 app 侧实现，需要先解决通道名冲突与 service 声明问题。
