                Log.e(TAG, "onAdFailedToLoad BannerAd - ErrorCode = $errorCode")
            }

            override fun onAdClosed() {

我忘了在网址中添加“ @ ”符号 ads:adUnitId="string/mainactivity_banner_ad_unit_id"位于activity_test.xml布局中

我很沮丧。这是正确的XML布局代码

<android.support.constraint.ConstraintLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   xmlns:ads="http://schemas.android.com/apk/res-auto"
   tools:context=".Activities.TestActivity">

   <com.google.android.gms.ads.AdView
    android:id="@+id/adViewTest"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="visible"
    ads:adSize="BANNER"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    ads:adUnitId="@string/mainactivity_banner_ad_unit_id" 
    app:layout_constraintBottom_toBottomOf="parent"
    />
</android.support.constraint.ConstraintLayout>
