Java Admob ads正在加载但未显示

所以在我的LIBGDX游戏中，我试图弹劾Admob广告

即使在刷新60秒或按下home（主页）按钮并再次进入游戏后，它们仍然可以正常加载，但不会显示

我在这个网站上找到了一些答案，但没有一个有帮助

以下是Android Launcher类的代码：

   public class AndroidLauncher extends AndroidApplication implements AdHander{

        private static final String TAG = "AndroidLauncher";
        protected AdView adView;
        private final int SHOW_ADS = 1;
        private final int HIDE_ADS = 0;

        Handler handler = new Handler(){
            @Override
            public void handleMessage(Message msg) {
                switch (msg.what){
                    case SHOW_ADS:
                        adView.setVisibility(View.VISIBLE);
                        break;
                    case HIDE_ADS:
                        adView.setVisibility(View.GONE);
                        break;
                }
            }
        };


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

            RelativeLayout layout = new RelativeLayout(this);
            AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
            View gameView = initializeForView(new Main(this), config);

            adView = new AdView(this);
            adView.setAdSize(AdSize.SMART_BANNER);

// HERE I IMPLEMENTED ADMOB TEST ID FOR BANNERS
            adView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");
            adView.setBackgroundColor(Color.BLACK);
            adView.setAdListener(new AdListener() {
                @Override
                public void onAdLoaded() {
                    int visibility = adView.getVisibility();
                    adView.setVisibility(AdView.GONE);
                    adView.setVisibility(visibility);
                    Log.i(TAG, "Ad loaded");
                }
            });

            AdRequest.Builder builder = new AdRequest.Builder();
            adView.loadAd(builder.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);

            config.useImmersiveMode = true;
            initialize(new Main(this), config);
        }

        @Override
        public void showAds(boolean show) {
            handler.sendEmptyMessage(show ? SHOW_ADS : HIDE_ADS);
        }
    }

我做错了什么？

检查您的舱单，它应该与此类似：-

@Override
public void showAds(boolean show) {
    Message msg = new Message();
    msg.what = show ? SHOW_ADS : HIDE_ADS;
    handler.sendMessage(msg);
}
