AdMob 广告未在 Android SDL 应用中正确显示

Question

我在我的应用中实施 AdMob 广告时遇到了问题。我正在使用SDL和本机代码。广告是在这样的onCreate方法中创建的：

@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);
}

我认为这段代码是正确的，因为广告位于屏幕上，但不可见。我可以触摸屏幕上应显示广告的位置，然后浏览器开始打开，因此广告实际上已加载。

在以下情况下，广告将正确显示：

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

我正在考虑一些刷新方法，但找不到解决此问题的方法。我试过的这个方法：

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？

更新

我检查了我的 logcat 输出，但我没有看到任何奇怪的东西：

在第 16 行，广告开始请求，在第 28 行有一条消息，表明广告已完成加载，但未显示在屏幕上。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，不知道是不是跟这个有关系？

Answer 1

我只是通过设置背景颜色来解决它：

adView.loadAd(request);
adView.setBackgroundColor(Color.TRANSPARENT);

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