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")
}
}
