下面是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>

在这里我的课

and here my class

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

感谢你对anwsering。

thank your for anwsering.

编辑：添加其它的XML布局文件相同的错误

add an other XML Layout File same Error

推荐答案

在 NullPointerException异常在 onMeasure 查看时 AD浏览报图形布局是一个已知的问题。这将是固定的下一个主要版本。

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

在此期间，编辑原始的XML或code定义的 AD浏览报工作得很好。

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