我确定我错过了xml布局文件中的内容，但我无法将其视为初学者。
聚苯乙烯。这里的布局是：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".AllJokes" >
<ListView
android:id="@+id/allJokesList"
android:layout_height="wrap_content"
android:layout_width="match_parent">
</ListView>
</RelativeLayout>
我应该在其中声明一些内容吗？请给我一个线索！

您无法向adapterview添加视图
答案 1 :(得分：2)
你的问题是
ListView layout = (ListView) findViewById(R.id.allJokesList);
layout.addView(adView);
您需要在适配器中添加adView http://googleadsdeveloper.blogspot.co.il/2012/03/embedding-admob-ads-within-listview-on.html
答案 2 :(得分：1)
请勿尝试将AdView添加为ListView中的元素。这是一个痛苦的食谱，因为它将与您的其他需求不同的项目完全不同。
在ListView的上方或下方添加它自己的元素。
而是在ListView
之上或之下创建LinearLayout<LinearLayout android:id="@+id/adViewContainer
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
然后将onCreate的这一部分更改为
// Add the AdView to the view hierarchy. The view will have no size
// until the ad is loaded.
final ViewGroup adViewContainer = (ViewGroup) findViewById(R.id.adViewContainer);
adViewContainer.addView(adView);
