#鸿蒙通关秘籍#如何将本地播放器的状态信息通知ArkWeb内核？

当应用接管网页的媒体播放后，需要将本地播放器的状态信息传递给ArkWeb内核。可以通过NativeMediaPlayerHandler对象进行这些状态的报告：

typescript // 自定义的播放器状态监听类 class ActualNativeMediaPlayerListener { handler: webview.NativeMediaPlayerHandler;

constructor(handler: webview.NativeMediaPlayerHandler) { this.handler = handler; }

onPlaying() { this.handler.handleStatusChanged(webview.PlaybackStatus.PLAYING); } onPaused() { this.handler.handleStatusChanged(webview.PlaybackStatus.PAUSED); } onDurationChanged(duration: number) { this.handler.handleDurationChanged(duration); } onBufferedTimeChanged(buffered: number) { this.handler.handleBufferedEndTimeChanged(buffered); } onTimeUpdate(time: number) { this.handler.handleTimeUpdate(time); } onEnded() { this.handler.handleEnded(); } onVideoSizeChanged(width: number, height: number) { this.handler.handleVideoSizeChanged(width, height); } }

在播放器创建时，实例化这个监听器并绑定给播放器：

typescript @Entry @Component struct WebComponent { controller: webview.WebviewController = new webview.WebviewController();

build() { Column() { Web({ src: 'www.example.com', controller: this.controller }) .enableNativeMediaPlayer({ enable: true, shouldOverlay: false }) .onPageBegin((event) => { this.controller.onCreateNativeMediaPlayer((handler: webview.NativeMediaPlayerHandler, mediaInfo: webview.MediaInfo) => { // instantiate the listener and bind it to the player's events let nativeMediaPlayerListener: ActualNativeMediaPlayerListener = new ActualNativeMediaPlayerListener(handler); // return the actual native player back to ArkWeb kernel return null; }); }) } } }
