如何知道是否AdMob的广告已经被加载 [英] How to know if AdMob ad has been loaded

问题描述

我的Andorid应用程序可以离线和在线。它显示的广告，当它处于联机模式。 在这样一个场景，它是工作在离线模式，用户在切换互联网连接，我想知道是否已经装入该广告。如果没有，那么我会加载一个新的广告。我看着AdMob的API（AD浏览报班），但无法找到的东西，做到这一点。

下面是执行我的 AdListener 据@Hounshell答案。但是，没有方法在这里实现都得到执行。

  adView.setAdListener（新AdListener（）{

        @覆盖
        公共无效onReceiveAd（广告为arg0）{
            Toast.makeText（法，广告收，Toast.LENGTH_LONG）.show（）;
        }

        @覆盖
        公共无效于presentScreen（广告为arg0）{
        }

        @覆盖
        公共无效onLeaveApplication（广告为arg0）{
            // TODO自动生成方法存根

        }

        @覆盖
        公共无效onFailedToReceiveAd（广告为arg0，错误code ARG1）{
            Toast.makeText（行为，无法接受广告，Toast.LENGTH_LONG）.show（）;
        }

        @覆盖
        公共无效onDismissScreen（广告为arg0）{
            // TODO自动生成方法存根

        }
    }）;
 

和main.xml中的一部分，涵盖了AD浏览报

 ＆LT;的FrameLayout
                    机器人：layout_width =FILL_PARENT
                    机器人：layout_height =50dp
                    ＆GT;
                ＆LT; com.google.ads.AdView
                    的xmlns：广告=htt​​p://schemas.android.com/apk/lib/com.google.ads
                    机器人：ID =@ + ID / AD浏览报
                    机器人：layout_width =FILL_PARENT
                    机器人：layout_height =FILL_PARENT
                    广告：adSize =大旗
                    广告：adUnitId =XXXXXXXXXXXXXXXX
                    广告：loadAdOnCreate =真/＆GT;
                ＆LT; /的FrameLayout＆GT;
 

解决方案

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

  AdView.setAdListener（新AdListener（）{
      //实现AdListener
    }）;
 

您AdL​​istener的 onReceiveAd（）时，广告可会叫， onFailedToReceiveAd（）将被称为焕广告不可用code解释为什么（包括网络无法使用，没有填充）

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.

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

        }
    });

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.com/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>

解决方案

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

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

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)
