我的 Andorid 应用程序可以离线和在线使用.它在在线模式下显示广告.在离线模式下工作并且用户打开互联网连接的情况下，我想知道广告是否已加载.如果没有，那么我会加载一个新广告.我查看了 AdMob API(AdView 类)，但找不到可以执行此操作的内容.

My Andorid app works offline and online. It displays ads when it is in online mode. In a scenario where it is working in offline mode and user switches the internet connectivity on, I want to know if the ad is already loaded. If not, then I would load a new ad. I looked at AdMob API (AdView class) but could not find something that does this.

根据@Hounshell 的回答，这是我的 AdListener 的实现.但是这里实现的方法都没有得到执行.

Here is the implementation of my AdListener according to the answer from @Hounshell. But none of the methods implemented here are getting executed.

        adView.setAdListener(new AdListener() {

        @Override
        public void onReceiveAd(Ad arg0) {
            Toast.makeText(act, "Ad received",Toast.LENGTH_LONG).show();
        }

        @Override
        public void onPresentScreen(Ad arg0) {
        }

        @Override
        public void onLeaveApplication(Ad arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onFailedToReceiveAd(Ad arg0, ErrorCode arg1) {
            Toast.makeText(act, "Failed to receive Ad",Toast.LENGTH_LONG).show();
        }

        @Override
        public void onDismissScreen(Ad arg0) {
            // TODO Auto-generated method stub

        }
    });

以及覆盖 AdView 的 main.xml 的一部分

And part of main.xml that covers the AdView

<FrameLayout 
                    android:layout_width="fill_parent"
                    android:layout_height="50dp"
                    >
                <com.google.ads.AdView
                    xmlns:ads="http://schemas.android/apk/lib/com.google.ads"
                    android:id="@+id/adView"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"
                    ads:adSize="BANNER"
                    ads:adUnitId="xxxxxxxxxxxxxxxx"
                    ads:loadAdOnCreate="true" />
                </FrameLayout>

推荐答案

来自 https://developers.google/mobile-ads-sdk/docs/android/intermediate#adlistener

AdView.setAdListener(new AdListener() {
      // Implement AdListener
    });

您的 AdListener 的 onReceiveAd() 将在广告可用时调用，onFailedToReceiveAd() 将在广告不可用时调用，并带有解释原因的代码(包括网络不可用和未填充)

Your AdListener's onReceiveAd() will be called when an ad is available, onFailedToReceiveAd() will be called whan an ad isn't available with a code explaining why (including network not available and no fill)
