Question

出于演示目的，该应用程序只有一项活动可以提供：

您点击一个按钮，查看奖励视频，您将获得任何奖励。

问题

如何加载视频？根据我所看到的情况，您只能拨打mAd.loadAd()一次。共有3个视频，每个视频都有自己的AD UNIT ID。每个广告单元都可以拥有自己的监听器，但只有一个视频加载，所以它并不重要...

尝试加载多个视频时

例如：

mAd1.loadAd("AD_UNIT_1", new AdRequest.Builder().build());
mAd2.loadAd("AD_UNIT_2", new AdRequest.Builder().build());
mAd3.loadAd("AD_UNIT_3", new AdRequest.Builder().build());

仅导致最后一个视频被加载，这在日志中显示：

W/Ads: Loading already in progress, saving this object for future refreshes.

的onCreate（）

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mAd1 = MobileAds.getRewardedVideoAdInstance(this);
    mAd2 = MobileAds.getRewardedVideoAdInstance(this);
    mAd3 = MobileAds.getRewardedVideoAdInstance(this);

    listeners...

    mAd1.loadAd() etc
}

感谢您的帮助

编辑：很明显我在想这个问题是错的。我有5个以上的广告区域，每个区域都会播放奖励视频并给予不同的奖励（例如，一个给出硬币，一个给出一个等级，等等......）。没有理由加载5个视频。我应该在onCreate()中加载一个，以便在需要时准备好，然后在项目获得奖励后再次加载，以便下次准备好。

所以问题仍然存在，如果只有一个视频，一个广告区域被加载onCreate()，那么我该如何追踪要给予的奖励？

这是一个简单的解决方案......

<强> MainActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mAd = MobileAds.getRewardedVideoAdInstance(this);

    mAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {

        @Override
        public void onRewarded(RewardItem rewardItem) {
            switch(Constants.currentAd) {
                case("REWARD1"):
                    //do something
                    Constants.currentAd = "";
                    break;

                case("REWARD2"):
                    //do something
                    Constants.currentAd = "";
                    break;

                case("REWARD3"):
                    //do something
                    Constants.currentAd = "";
                    break;
            }
        }
    });

   mAd.loadAd("REWARDED_VIDEO_UNIT_ID", new AdRequest.Builder().build());
}

public void showRewardedVideo() {
        if (mAd.isLoaded()) {
            mAd.show();
        }
    }

<强> Constants.java

public class Constants {
    public static String currentAd = "";
}

点击按钮后显示广告

rewardButton1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Constants.currentAd = "REWARD1";
                dismiss();
                ((MainActivity) getActivity()).showRewardedVideo();
            }
        });

REWARDED_VIDEO_UNIT_ID是AdMob中获奖视频的一个广告单元...删除其余部分。不需要其他单位，你可以在听众中追踪你喜欢的任何内容。
