我的应用使用了以下 InterstitialAd，以下是从谷歌示例中获得的标准编码。但是，我想问一下为什么没有广告节目？（应用程序正确显示吐司：在 ReceiveAd 上）

我的 main_first_page 布局底部也有一个广告横幅。这会影响 InterstitialAd 吗？

谢谢！！

public class StartUp extends Activity implements AdListener {

    private InterstitialAd interstitialAd;   
    AdView adView;
    private static final String LOG_TAG = "IQ!";

       public static final  String MY_PUBLISHER_ID = "abc"; 

       @Override
       public void onCreate(Bundle savedInstanceState) 
       {
          super.onCreate(savedInstanceState); // call the superclass's method
          setContentView(R.layout.main_first_page); // inflate the GUI


          Button ButtonNum= (Button) findViewById(R.id.buttonB);
          Button ButtonHeart= (Button) findViewById(R.id.buttonC);
          Button ButtonMath= (Button) findViewById(R.id.buttonD);             

           interstitialAd = new InterstitialAd(this, MY_PUBLISHER_ID); // Create an ad.  
              interstitialAd.setAdListener(this); // Set the AdListener.
              AdRequest adRequest = new AdRequest();
              adRequest.addTestDevice(AdRequest.TEST_EMULATOR);
              interstitialAd.loadAd(adRequest);       

              if (interstitialAd.isReady()) {interstitialAd.show();} 
              else {Log.d(LOG_TAG, "Interstitial ad was not ready to be shown.");}            
       }
/** Called when an ad is clicked and about to return to the application. */
          @Override
          public void onDismissScreen(Ad ad) {
            Log.d(LOG_TAG, "onDismissScreen");
            Toast.makeText(this, "onDismissScreen", Toast.LENGTH_SHORT).show();
          }

/** Called when an ad was not received. */
          @Override
          public void onFailedToReceiveAd(Ad ad, AdRequest.ErrorCode error) {
            String message = "onFailedToReceiveAd (" + error + ")";
            Log.d(LOG_TAG, message);
            Toast.makeText(this, message, Toast.LENGTH_SHORT).show();
          }

/** Called when an ad is clicked and going to start a new Activity that will
           * leave the application (e.g. breaking out to the Browser or Maps
           * application).
           */
          @Override
          public void onLeaveApplication(Ad ad) {
            Log.d(LOG_TAG, "onLeaveApplication");
            Toast.makeText(this, "onLeaveApplication", Toast.LENGTH_SHORT).show();
          }

/* Called when an Activity is created in front of the app (e.g. an
           * interstitial is shown, or an ad is clicked and launches a new Activity).
           */         
        @Override
        public void onPresentScreen(Ad arg0) {
            // TODO Auto-generated method stub          
        }

/** Called when an ad is received. */
        @Override
          public void onReceiveAd(Ad ad) {
            Log.d(LOG_TAG, "onReceiveAd");
            Toast.makeText(this, "onReceiveAd", Toast.LENGTH_SHORT).show();
        }

插页式广告需要时间来加载。您正在检查它是否在加载后直接准备好，所以它肯定还没有准备好。检查您的 logcat 输出，您可能会看到"Interstitial ad was not ready to be shown."您记录的消息。

onReceiveAd()在调用回调之前，插页式广告不会准备好。您可以安全地放置interstitialAd.show()在onReceiveAd()回调中，插页式广告会立即显示。

另一个用例可能是您希望稍后显示插页式广告，例如游戏关卡的结束。在这种情况下，您将在关卡开始时预加载插页式广告，并在关卡isReady结束时查看标志以查看插页式广告是否已准备好。
