原生视频广告

MediaContent

借助原生广告，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。

Java

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

Kotlin

if (myNativeAd.getMediaContent().hasVideoContent()) {
  val mediaAspectRatio: Float = myNativeAd.getMediaContent().getAspectRatio()
  val duration: Float = 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。

Java

myNativeAd.getMediaContent().getVideoController()
        .setVideoLifecycleCallbacks(new VideoLifecycleCallbacks() {

  /** Called when video playback first begins. */
  @Override
  public void onVideoStart() {
    // Do something when the video starts the first time.
    Log.d("MyApp", "Video Started");
  }

  /** Called when video playback is playing. */
  @Override
  public void onVideoPlay() {
    // Do something when the video plays.
    Log.d("MyApp", "Video Played");
  }

  /** Called when video playback is paused. */
  @Override
  public void onVideoPause() {
    // Do something when the video pauses.
    Log.d("MyApp", "Video Paused");
  }

  /** Called when video playback finishes playing. */
  @Override
  public void onVideoEnd() {
    // Do something when the video ends.
    Log.d("MyApp", "Video Ended");
  }

  /** Called when the video changes mute state. */
  @Override
  public void onVideoMute(boolean isMuted) {
    // Do something when the video is muted.
    Log.d("MyApp", "Video Muted");
  }
});

Kotlin

myNativeAd.getMediaContent().getVideoController().setVideoLifecycleCallbacks {

  /** Called when video playback first begins. */
  override fun onVideoStart() {
    // Do something when the video starts the first time.
    Log.d("MyApp", "Video Started")
  }

  /** Called when video playback is playing. */
  override fun onVideoPlay() {
    // Do something when the video plays.
    Log.d("MyApp", "Video Played")
  }

  /** Called when video playback is paused. */
  override fun onVideoPause() {
    // Do something when the video pauses.
    Log.d("MyApp", "Video Paused")
  }

  /** Called when video playback finishes playing. */
  override fun onVideoEnd() {
    // Do something when the video ends.
    Log.d("MyApp", "Video Ended")
  }

  /** Called when the video changes mute state. */
  override fun onVideoMute(boolean isMuted) {
    // Do something when the video is muted.
    Log.d("MyApp", "Video Muted")
  }
}
