这是xml文件

<RelativeLayout xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/backgroundapp"
android:orientation="vertical" >



<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_alignParentBottom="true"
  android:orientation="vertical"
  android:gravity="bottom"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">

    <ListView android:id="@id/android:list"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:cacheColorHint="#00000000"
    android:textColor="#FFFFFF"/>

    <Button
    android:id="@+id/add_main_btn"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:text="@string/add_serie" />

</LinearLayout>



<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads" android:layout_alignParentTop="true" android:id="@+id/ad_layout" android:orientation="vertical" android:gravity="top" android:layout_width="fill_parent" android:layout_height="fill_parent">

    <com.google.ads.AdView android:id="@+id/adView" android:layout_width="wrap_content" android:layout_height="wrap_content" ads:adUnitId="a15086a2a707a22" ads:adSize="BANNER" ads:loadAdOnCreate="true" />

</LinearLayout>

</RelativeLayout>

这里是我的班级

adView = new AdView(this, AdSize.BANNER, MY_AD_UNIT_ID);
    LinearLayout layout = (LinearLayout)findViewById(R.id.adView);
    layout.addView(adView);
    adView.loadAd(new AdRequest());

感谢您的回复.

添加另一个 XML 布局文件相同的错误

        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:text="@string/add_serie" />

    <ListView
        android:id="@id/android:list"

        android:layout_alignParentLeft="true"
        android:cacheColorHint="#00000000"
        android:textColor="#FFFFFF" >

    </ListView>

    <com.google.ads.AdView 
    android:id="@+id/adView" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"

已解决的问题 Admob 6.2.1 有一个针对 Android 4.1.2 的错误，将 Api 布局设置为 10 或更低，有新的错误消息但不影响程序或广告

Problem solved Admob 6.2.1 has a bug for Android 4.1.2 set the Api layout to 10 or lower, have new error messages but doesnt effect the programm or ad

推荐答案

onMeasure 中的NullPointerException 在查看AdView 图形布局时一个已知问题.它将在下一个主要版本中修复.

The NullPointerException in onMeasure when viewing an AdView the graphical layout is a known issue. It will be fixed for the next major release.

与此同时，编辑原始 XML 或在代码中定义 AdView 工作正常.

In the meantime, editing the raw XML or defining an AdView in code works just fine.
