原生视频广告

MediaContent

借助原生广告和自定义原生广告格式，您可以访问 MediaContent 对象，该对象用于获取与媒体内容（可以是视频或者图片）相关的信息。该对象也可用于控制视频广告播放和监听播放事件。您可以通过调用 NativeAd.getMediaContent() 来获取 MediaContent 对象。

MediaContent 对象包含视频的宽高比和时长等信息。以下代码段显示了如何获取原生广告的宽高比和时长。

Kotlin

if (myNativeAd.mediaContent.hasVideoContent) {
  val mediaAspectRatio: Float = myNativeAd.mediaContent.aspectRatio
  val duration: Float = myNativeAd.mediaContent.duration
  // ...
}

Java

if (myNativeAd.getMediaContent().getHasVideoContent()) {
  float mediaAspectRatio = myNativeAd.getMediaContent().getAspectRatio();
  float duration = myNativeAd.getMediaContent().getDuration();
  // ...
}

视频事件的回调

如需处理特定视频事件，请编写一个扩展抽象 VideoLifecycleCallbacks 类的类，并对 VideoController 调用 setVideoLifecycleCallbacks()。然后，仅替换所需的回调。

Kotlin

val videoController = myNativeAd.mediaContent.videoController
videoController.videoLifecycleCallbacks = object : VideoController.VideoLifecycleCallbacks {
  override fun onVideoStart() {
    Log.d("MyApp", "Video Started")
  }

  override fun onVideoPlay() {
    Log.d("MyApp", "Video Played")
  }

  override fun onVideoPause() {
    Log.d("MyApp", "Video Paused")
  }

  override fun onVideoEnd() {
    Log.d("MyApp", "Video Ended")
  }

  override fun onVideoMute(boolean isMuted) {
    Log.d("MyApp", "Video Muted")
  }
}

Java

VideoController videoController = myNativeAd.getMediaContent().getVideoController();
videoController.setVideoLifecycleCallbacks(new VideoLifecycleCallbacks() {
  @Override
  public void onVideoStart() {
    Log.d("MyApp", "Video Started");
  }

  @Override
  public void onVideoPlay() {
    Log.d("MyApp", "Video Played");
  }

  @Override
  public void onVideoPause() {
    Log.d("MyApp", "Video Paused");
  }

  @Override
  public void onVideoEnd() {
    Log.d("MyApp", "Video Ended");
  }

  @Override
  public void onVideoMute(boolean isMuted) {
    Log.d("MyApp", "Video Muted");
  }
});
