原生视频广告

MediaContent

原生广告和自定义原生广告格式 让发布商能够 MediaContent 该对象用于获取媒体内容相关信息，内容可以是 视频或图片。它还用于控制视频广告播放和监听 播放事件。您可以通过调用MediaContent NativeAd.getMediaContent()。

MediaContent 对象包含宽高比和 视频的时长。以下代码段展示了如何获取宽高比和 原生广告的持续时间。

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

要处理特定视频事件，请编写一个类来扩展抽象 VideoLifecycleCallbacks 类，以及调用 setVideoLifecycleCallbacks() 在 VideoController 上。然后，仅替换您关注的回调。

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")
  }
}
