原生影片廣告

MediaContent

原生廣告會提供 MediaContent 物件存取權，用於取得媒體內容 (可能是影片或圖片) 的相關資訊。也用於控制影片廣告播放，並監聽播放事件。您可以呼叫 NativeAd.getMediaContent() 取得 MediaContent 物件。

MediaContent 物件包含影片的顯示比例和長度等資訊。下列程式碼片段顯示如何取得原生廣告的顯示比例和時間長度。

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();
  // ...
}

影片事件的回呼

如要處理特定影片事件，請編寫可擴充抽象 VideoLifecycleCallbacks 類別的類別，並在 VideoController 上呼叫 setVideoLifecycleCallbacks()。然後只覆寫您在意的回呼。

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");
  }
});
