java - Interstitial Ad 的 Listener 的 onAdLoaded() 不会运行

Question

interstitial.setAdListener(new AdListener(){
    public void onAdLoaded(){
        display();
    }
});

我尝试使用调试器，第一行运行了，但第二行根本没有运行。这是我在 onCreate 方法中初始化广告的方式:

interstitial = new InterstitialAd(this);
interstitial.setAdUnitId("******************************");
AdRequest adRequest = new AdRequest.Builder().build();
interstitial.loadAd(adRequest);

和 InterstitialAd interstitial; 在类内部的方法之外。 AdUnitId 被故意抹去。

Answer 1

onAdLoaded() 方法之前是否缺少@override
