我正在使用 WebView 并且我已经设置了所有内容。如果用户访问名为 X 的网站，广告就会出现。如果用户关闭广告而不跟踪它，我希望 WebView 页面后退一步。我怎样才能做到这一点？本想把它加到onRewardedVideoAdClosed()端，但是视频播放成功的用户也退了一步。

  @Override
public void onRewardedVideoAdClosed() { 
    Toast.makeText(getActivity(), "Reklam sayfası kapatıldı.", Toast.LENGTH_SHORT).show();
    loadRewardedVideoAd();
    webView.goBack(); //doesn't work
}

 private void loadRewardedVideoAd() { 
    mRewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917",
            new AdRequest.Builder().build());
}


@Override
public void onRewarded(RewardItem reward) {
    Toast.makeText(getActivity(), "Başarılı! İçerik görüntüleme hakkı kazandınız. " ,/*+ reward.getType() + "  amount: " + reward.getAmount(),*/ Toast.LENGTH_SHORT).show();
    // Reward the user.

}

@Override
public void onRewardedVideoAdLeftApplication() {
    Toast.makeText(getActivity(), "onRewardedVideoAdLeftApplication", Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoAdClosed() {
    Toast.makeText(getActivity(), "Reklam sayfası kapatıldı.", Toast.LENGTH_SHORT).show();
    loadRewardedVideoAd();
}

@Override
public void onRewardedVideoAdFailedToLoad(int errorCode) {
    Toast.makeText(getActivity(), "Reklam yükelmesi başarısız oldu.", Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoAdLoaded() {
    Toast.makeText(getActivity(), "Geçiş reklamları hazır.", Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoAdOpened() {
    Toast.makeText(getActivity(), "Geçiş reklamı açıldı.", Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoStarted() {
    Toast.makeText(getActivity(), "Geçiş reklamı başladı.", Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoCompleted() {
    Toast.makeText(getActivity(), "Reklam bitti.", Toast.LENGTH_SHORT).show();
}

@Override
public void onResume() {
    mRewardedVideoAd.resume(getActivity());
    super.onResume();
}

@Override
public void onPause() {
    mRewardedVideoAd.pause(getActivity());
    super.onPause();
}

@Override
public void onDestroy() {
    mRewardedVideoAd.destroy(getActivity());
    super.onDestroy();
}

您可以简单地记住，如果用户获得了奖励。下面的代码基于新的 API，但是用旧的 API 实现这个想法应该很简单。

        RewardedAdCallback adCallback = new RewardedAdCallback() {
            boolean rewardEarned = false;

            @Override
            public void onRewardedAdOpened() {
                // Ad opened.
            }

            @Override
            public void onRewardedAdClosed() {
                loadAd();
                showResponse(rewardEarned ? R.string.rewardEarned : R.string.adAborted);
            }

            @Override
            public void onUserEarnedReward(@NonNull RewardItem reward) {
                rewardEarned = true;
            }

            @Override
            public void onRewardedAdFailedToShow(int errorCode) {
                // Ad failed to display
            }
        };
