广告不可见。不刷新广告

Question

我制作了一个免费的安卓游戏，我想给它添加一个横幅。我关注了this tutorial，但我不知道为什么它不起作用。

当我在 LogCat 中的模拟器上运行我的游戏时，我看到一条消息“广告不可见。未刷新广告。”当我在手机上安装游戏时，我也看不到任何广告。

这是我的 main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:ads="http://schemas.android.com/apk/res-auto"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">
  <com.google.android.gms.ads.AdView android:id="@+id/adView"
                         android:layout_width="wrap_content"
                         android:layout_height="wrap_content"
                         ads:adUnitId="hidden"
                         ads:adSize="BANNER"/>
</LinearLayout>

这是 MainActivity.java 中的代码

public class MainActivity extends AndroidApplication {
    private AdView adView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();
        cfg.useGL20 = true;
        cfg.useAccelerometer = true;
        cfg.useCompass = true;

        setContentView(R.layout.main);

        // Look up the AdView as a resource and load a request.
        adView = (AdView)this.findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);

        initialize (new RedSquare(), cfg);
    }

    @Override
    public void onPause() {
      adView.pause();
      super.onPause();
    }

    @Override
    public void onResume() {
      super.onResume();
      adView.resume();
    }

    @Override
    public void onDestroy() {
      adView.destroy();
      super.onDestroy();
    }
}

我发现使用adMob 在文件中明确定义布局可能是一个非常令人头疼的生成器，因为有时它可能会因某些参数和布局组合而变得难以预测。似乎总是有效的是将AdView动态添加到一些LinearLayout。

这应该可行：

final LinearLayout fragLayout = (LinearLayout) inflater.inflate(R.layout.your_layout, container, false);
final AdView adView = new AdView(getActivity());
adView.setAdUnitId("your-admob-id");
adView.setAdSize(AdSize.BANNER);

// Here you'll append the new AdView
final LinearLayout publiView = (LinearLayout) fragLayout.findViewById(R.id.publi);
publiView.addView(adView);

final AdRequest.Builder adReq = new AdRequest.Builder();
// You should include a line like this for testing purposes,
// but only after you've tested whether your AdView works!
// This will prevent your ad being loaded each time you test
// your ad, so it will prevent you being blocked from AdMob.
// You'll find your device_id in the LogCat.
adReq.addTestDevice("your_device_id");

final AdRequest adRequest = adReq.build();
adView.loadAd(adRequest);

---- 编辑----

此实现适用于 Fragments，您可能正在运行 Activity，这就是您收到这些错误的原因。

• 将getActivity()替换为this

• inflater 只是（正如它的名字所说）从布局文件中扩充一个新的LinearLayout。这意味着我已经定义了一个布局，我称之为your_layout 并在LinearLayout 中定义。充气机只是创建了一个 `LinearLayout.在您的情况下，可能没有必要。

我正在添加一个可能对你有用的代码：

final LinearLayout yourLayout = (LinearLayout) findViewById(R.id.your_linearlayout_id_where_you_want_to_put_your_adview);

final AdView adView = new AdView(this);
adView.setAdUnitId("your-admob-id");
adView.setAdSize(AdSize.BANNER);

yourLayout.addView(adView);

final AdRequest.Builder adReq = new AdRequest.Builder();
// You should include a line like this for testing purposes,
// but only after you've tested whether your AdView works!
// This will prevent your ad being loaded each time you test
// your ad, so it will prevent you being blocked from AdMob.
// You'll find your device_id in the LogCat.
adReq.addTestDevice("your_device_id");

final AdRequest adRequest = adReq.build();
adView.loadAd(adRequest);

要在 libgdx 中展示广告，您需要初始化您的应用查看。所以，替换所有这些：

setContentView(R.layout.main);

// Look up the AdView as a resource and load a request.
adView = (AdView)this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);

initialize (new RedSquare(), cfg);

有了这个：

RelativeLayout layout = new RelativeLayout(this);

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
View gameView = initializeForView(new RedSquare(), cfg);

AdView AdView = new AdView(this);
AdView.setAdSize(AdSize.SMART_BANNER);
AdView.setAdUnitId("***"); //The AdUnitId
AdRequest.Builder adRequest = new AdRequest.Builder();
adRequest.addTestDevice("***"); //Your Test device if any
AdView.loadAd(adRequest.build());

layout.addView(gameView);

RelativeLayout.LayoutParams adParams = 
    new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, 
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
adParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
adParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);

layout.addView(AdView, adParams);

setContentView(layout);

您的布局没有什么特别的问题。虽然我可能会将 AdView 的 layout_width 更改为：

android:layout_width="match_parent"

但不清楚是什么

initialize (new RedSquare(), cfg);

在做什么？我怀疑它正在改变布局。
