我有以下代码。我看不到任何广告，但在日志消息中，我看到广告已完成加载。
我所做的只是阅读json并显示数据。我在布局xml中没有任何东西，我正在动态创建所有视图元素....

答案 0 :(得分：3)
您可能遇到问题，因为您正在从#onCreate调用#displayInterstitial。 不应在加载后立即调用#displayInterstitial。
您应该在应用中的自然断点处调用#displayInterstitial。
答案 1 :(得分：0)
尝试在onCreate上对其进行初始化，但只能从事件（例如单击按钮）中调用show（）方法。
您可以使用此代码，id起作用。
@Override
protected void onCreate(Bundle savedInstanceState) {
...
MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713"); //test id
mInterstitialAd = new InterstitialAd(this);
mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712");
mInterstitialAd.loadAd(new AdRequest.Builder().build());
mInterstitialAd.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
// Code to be executed when an ad finishes loading.
}
@Override
public void onAdFailedToLoad(int errorCode) {
// Code to be executed when an ad request fails.
}
@Override
public void onAdOpened() {
// Code to be executed when the ad is displayed.
}
@Override
public void onAdLeftApplication() {
// Code to be executed when the user has left the app.
}
@Override
public void onAdClosed() {
// Code to be executed when when the interstitial ad is closed.
}
});
...
btn_test.setOnClickListener(view -> {
showInterstitial();
});
private void showInterstitial()
{
if (mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
} else {
Log.d("TAG", "The interstitial wasn't loaded yet.");
}
}
