Android-智能横幅广告在纵向模式下不显示在屏幕上

Question

我在我的应用程序中使用广告，并且我已按照此处的教程进行操作:https://developers.google.com/admob/android/banner

如果我在 xml 中将 adSize 设置为“BANNER”，一切正常，但广告在横向模式或大屏幕上看起来不太好。所以现在我正在尝试将 adSize 更改为“SMART_BANNER”，但出于某种原因，横幅仅在横向模式下显示，而在纵向模式下我只有一个白色的广告 View 。我在这里缺少什么？

代码如下:

activity_main.xml:

好的..我发现了问题...

请从您的 Adview 中删除所有边距。 替换这个

<com.google.android.gms.ads.AdView 
 xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/adView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="8dp"
    android:layout_marginEnd="8dp"
    android:layout_marginLeft="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginStart="8dp"
    ads:adSize="SMART_BANNER"
    ads:adUnitId="@string/ad_id"
    ads:layout_constraintBottom_toBottomOf="parent"
    ads:layout_constraintLeft_toLeftOf="parent"
    ads:layout_constraintRight_toRightOf="parent">
</com.google.android.gms.ads.AdView>

为此-

<com.google.android.gms.ads.AdView 
 xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/adView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    ads:adSize="SMART_BANNER"
    ads:adUnitId="@string/ad_id"
    ads:layout_constraintBottom_toBottomOf="parent"
    ads:layout_constraintLeft_toLeftOf="parent"
    ads:layout_constraintRight_toRightOf="parent">
</com.google.android.gms.ads.AdView>

因为横幅现在将占据全宽并且可以显示。问题是，对于边距，它没有足够的宽度来显示......
