我正在尝试将 admob 奖励视频广告集成到我的网络视图应用程序中。我该如何使用javascript来解决这个问题？

我已经加载了视频，但对如何在使用 javascript 单击按钮时显示视频感到困惑。

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

@Override
public void onRewarded(RewardItem reward) {
    Toast.makeText(this, "onRewarded! currency: " + reward.getType() + "  amount: " +
            reward.getAmount(), Toast.LENGTH_SHORT).show();
    // Reward the user.
}

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

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

@Override
public void onRewardedVideoAdFailedToLoad(int errorCode) {
    Toast.makeText(this, "onRewardedVideoAdFailedToLoad", Toast.LENGTH_SHORT).show();
}

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

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

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

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

public class MyJavaScriptInterface {

    @JavascriptInterface // this annotation is important
    public void startRewardVideoAndroidFunction(String paramFromJS) {
        if (mRewardedVideoAd.isLoaded()) {
                mRewardedVideoAd.show();
        }
    }
}

当在页面上单击一个按钮时，我需要运行一个调用 java 方法的 javascript 函数。
