我的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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000000"
    android:orientation="vertical" >
<com.google.ads.AdView android:id="@+id/ad"
                           android:layout_width="wrap_content"
                           android:layout_height="wrap_content"
                           ads:adSize="SMART_BANNER"
                           ads:adUnitId="@string/admob_unit_id"
                           ads:testDevices="@string/test_device"
                           ads:loadAdOnCreate="true"/>

</LinearLayout>

谁能告诉我我在哪里犯错？

如果您仔细查看您发布的日志，在第 6 行您会注意到googleads.g.doubleclick.net解析为127.0.0.1. 这通常意味着hosts您手机上的文件已被篡改，目的是阻止您所有应用中的广告。

如果你在模拟器上运行它，你的模拟器的hosts文件被篡改了，或者你的计算机的操作系统hosts文件被篡改了。你应该检查一下。
