请原谅我的无知，我是编程的新手。不确定如何将AdMob AdView与ListView集成到我的应用中。当我尝试使用此代码运行它时，应用程序会一直崩溃：
这是我的主要活动xml：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:background = "@drawable/ocean_three"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.google.ads.AdView android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adUnitId="123456789"
ads:adSize="BANNER"
ads:loadAdOnCreate="true"/>
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="@null"
android:dividerHeight="0dp"
android:listSelector="@drawable/list_selector">
</ListView>
</LinearLayout>
这里是logcat：
