我想在我的应用程序中包含一个 admob 横幅，但我收到了这个奇怪的错误。任何帮助都深表感谢。
这是xml代码
<com.google.ads.AdView android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="bottom"
ads:adUnitId="..."
ads:adSize="BANNER"
/>
在活动中，我写了以下代码
adview = (AdView)findViewById(R.id.adView);
adview.setVisibility(View.VISIBLE);
AdRequest re = new AdRequest();
adview.loadAd(re);
在 Logcat 中，我收到以下错误
Not enough space to show ad! Wants: <480, 75>, Has: <0, 800>
我怀疑肯定还有其他问题，因为我将 AdView 的宽度设置为“wrap_content”
在 xml 文件的图形视图中有这个警告
当我点击这个错误时，我看到有一个 java.lang.UnsupportedOperationException
如果您想进一步调查这里是完整的异常堆栈跟踪
