android - android InterstitialAd没有显示

我的应用程序使用了以下InterstitialAd，以下是从Google示例获得的标准编码。但是，我想问一下为什么没有广告展示？ （应用正确显示吐司：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();
        }

最佳答案

插页式广告需要花费一些时间才能加载。您正在检查加载后是否已经准备就绪，因此它肯定还没有准备好。检查您的logcat输出，您可能会看到记录的"Interstitial ad was not ready to be shown."消息。

在调用onReceiveAd()回调之前，插页式广告无法准备就绪。您可以安全地将interstitialAd.show()放在onReceiveAd()回调中，并且插页式广告会立即显示。

另一个用例可能是您想在以后（例如游戏关卡结束时）显示插页式广告。在这种情况下，您可以在关卡的开始处预加载插页式广告，然后在关卡的末尾查询isReady标志以查看插页式广告是否已准备好。
