找不到com.google.android.gms.ads.AdView

Question

我已经为此尝试了所有可能的解决方案，但没有任何效果。我一直收到这条消息：

尝试设置广告时！

我更新了我的sdk，更新了所有工具，导入并引用了google-play-services-lib，将其添加到活动下的清单中：

 <activity
        android:name=".MainActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
       <meta-data android:name="com.google.android.gms.version"
       android:value="@integer/google_play_services_version"/>

这是我的xml：

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

另外最重要的是：

     xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"

你可以看到它被引用：

什么都行不通，我做错了什么？

Answer 1

更改：

xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"

为：

xmlns:ads="http://schemas.android.com/apk/res-auto"

Answer 2

对我有用的是在代码中创建它：

AdView mAdView = new AdView(this);
        mAdView.setAdSize(AdSize.BANNER);
        mAdView.setAdUnitId("ca-app-pub-1147729513575655/6913222649");
        AdRequest adRequest = new AdRequest.Builder()
            .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
            .build();
        if(mAdView.getAdSize() != null || mAdView.getAdUnitId() != null)
        mAdView.loadAd(adRequest); 
       // else Log state of adsize/adunit
    ((RelativeLayout)findViewById(R.id.adView)).addView(mAdView );
