java - 在 Android 中设置委托(delegate)

Question

我需要完成以下任务:

AdBuddiz.RewardedVideo.setDelegate(delegate);

此 SDK 的文档显示“委托(delegate)必须实现以下接口(interface)”:

interface AdBuddizRewardedVideoDelegate {
  void didComplete();    // user fully watched the video, give the reward here 

  // optional
  void didFetch();       // a video is ready to be displayed
  void didFail(AdBuddizRewardedVideoError error); // SDK was unable to fetch or show a video
  void didNotComplete(); // an error happened during video playback
}

我熟悉 iOS 中的委派，但我不熟悉它在 Java/Android 中的工作原理。任何帮助表示赞赏。

Answer 1

我不熟悉你正在使用的类，但看起来你只需要实现这个接口(interface)。您可以使用匿名类来完成此操作。类似的东西

myRewardVideo.setDelegate(new AdBuddizRewardedVideoDelegate() {

    @Override
    public void didComplete() {
        // write what you want to happen here.
    }

    @Override
    public void didFetch() {
        // write what you want to happen here.
    }

    @Override
    public void didFail(AdBuddizRewardedVideoError error) {
        // write what you want to happen here.
    }

    @Override
    public void didNotComplete() {
        // write what you want to happen here.
    }
});

最后 3 个方法是可选的，因此如果您不希望在这些情况下发生任何事情，您可以删除这些方法。
