AdMob广告未正确显示在Android SDL应用程序中

Question

我在应用程序中实现AdMob广告时遇到了一个问题。我使用SDL和本机代码。广告是在onCreate方法中创建的，如下所示：

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    Log.v("SDL", "onCreate():" + mSingleton);
    super.onCreate(savedInstanceState);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    SDLActivity.initialize();
    mSingleton = this;
    mSurface = new SDLSurface(getApplication());
    mLayout = new RelativeLayout(this);
    adView = new AdView( this );
    adView.setAdUnitId("ca-app-pub-XXXXXXXXXXXXXXXX/XXXXXXXXXX");
    adView.setAdSize(AdSize.BANNER);
    request = new AdRequest.Builder()
    .addTestDevice("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX")
    .build();
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
    params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    adView.loadAd(request);
    mLayout.addView(mSurface);
    mLayout.addView(adView, params);
    setContentView(mLayout);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

我认为这个代码是正确的，因为广告位于屏幕上，但它是不可见的。我可以触摸广告所在位置的屏幕，浏览器开始打开，所以广告实际上已经加载。

然后广告将显示正确时：

• 是时候刷新了（在AdMob帐户上设置，我设置了30秒）
• 当Activity类调用onPause和onResume方法时，我退出应用程序，然后继续

我在考虑一些刷新方法，但找不到任何方法来解决这个问题。我尝试过的方法：

adView.refreshDrawableState();
adView.setActivated( true );
adView.setEnabled( true );
adView.setFocusable( true );
adView.setHovered( true );
adView.showContextMenu();

我不知道还能做什么。有什么建议吗？

我已经检查了我的logcat输出，但我没有发现任何奇怪的地方：

在第16行，广告开始了一个请求，在第28行，有一条消息表明广告已经完成加载，但它没有显示在屏幕上。60秒后，启动另一个请求（第37行），完成后，广告出现在屏幕上。最后一行有一条消息说nativeOnDraw失败了，我不知道这是否与此有关？

Answer 1

我只通过设置背景色就解决了这个问题：

adView.loadAd(request);
adView.setBackgroundColor(Color.TRANSPARENT);
mLayout.addView(mSurface);
mLayout.addView(adView, params);

Answer 2

你能试着改变这个顺序吗？

adView.loadAd(request);
mLayout.addView(mSurface);
mLayout.addView(adView, params);

收件人：

mLayout.addView(mSurface);
mLayout.addView(adView, params);
adView.loadAd(request);

因为您的视图未添加到ViewGroup中，所以第一次运行时可能会出现问题。问题是，AdMob非常聪明，它会检查AdView和家长是否可见。所以，因为你当时没有父母，所以它会安排在X秒后检查。这就是为什么你会在一段时间后看到。
