【问题描述】：

大家好，我在 android webview 中使用 admob。当我集成 admob 并运行时，它显示以下错误。我的代码如下：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<com.google.ads.AdView
    android:id="@+id/adViews"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="false"
    android:layout_centerHorizontal="true"
    ads:adSize="BANNER"
    ads:adUnitId="ca-123456" >
</com.google.ads.AdView>

<LinearLayout
    android:layout_alignParentTop="true"
    android:layout_above="@id/adView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ProgressBar
        android:id="@+id/progressBar1"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
   />

    <WebView
        android:id="@+id/webView1"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />
</LinearLayout>

在我用作的代码中：

 private InterstitialAd interstitial;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    overridePendingTransition(R.anim.trans_left_in, R.anim.trans_left_out);
    setContentView(R.layout.activity_news);


     interstitial = new InterstitialAd(News.this);
        // Insert the Ad Unit ID
        interstitial.setAdUnitId("ca-app123456");

        //Locate the Banner Ad in activity_main.xml
        AdView adView = (AdView) this.findViewById(R.id.adViews);

        // Request for Ads
        AdRequest adRequest = new AdRequest.Builder()

        // Add a test device to show Test Ads..comment for real app when launching
         .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
         .addTestDevice("CC5F2C72DF2B356BBF0DA198")
                .build();

        // Load ads into Banner Ads
        adView.loadAd(adRequest);

        // Load ads into Interstitial Ads
        interstitial.loadAd(adRequest);

        // Prepare an Interstitial Ad Listener
        interstitial.setAdListener(new AdListener() {
            public void onAdLoaded() {
                // Call displayInterstitial() function
                displayInterstitial();
            }
        });
    }
    public void displayInterstitial() {
        // If Ads are loaded, show Interstitial else show nothing.
        if (interstitial.isLoaded()) {
            interstitial.show();
        }

    web=(WebView)findViewById(R.id.webView1);

    web.setWebViewClient(new WebViewClient());
    pb=(ProgressBar)findViewById(R.id.progressBar1);
    ActionBar ab=getActionBar();
    ColorDrawable cd=new ColorDrawable(Color.parseColor("#000000"));
    ab.setBackgroundDrawable(cd);
    ab.setDisplayHomeAsUpEnabled(true);

    WebSettings ws=web.getSettings();
    ws.setBuiltInZoomControls(true);
    web.setWebViewClient(new WebViewClient());

    web.setWebChromeClient(new WebChromeClient() {
      //showing webview
     }
     }

当我运行代码时，它显示以下错误：

标签： android android-layout android-webview admob

【解决方案1】：

我想您是通过 google play 服务库使用 admob 而不是旧的/已弃用的 admob sdk jar，所以在您的布局中进行更改：

<com.google.ads.AdView
    android:id="@+id/adViews"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="false"
    android:layout_centerHorizontal="true"
    ads:adSize="BANNER"
    ads:adUnitId="ca-123456" >
</com.google.ads.AdView>

到：

<com.google.android.gms.ads.AdView
    android:id="@+id/adViews"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="false"
    android:layout_centerHorizontal="true"
    ads:adSize="BANNER"
    ads:adUnitId="ca-123456"/>

【解决方案2】：

所以 Stacktrace 说 “找不到类 com.google.ads.AdView”

那是因为您可能正在通过 Google Play 服务使用 Admob SDK，这在 8 月 1 日是强制性的。（否则您将无法将应用程序上传到 Play 商店）。因此，您需要使用 com.google.android.gms.ads.AdView 而不是使用 com.google.ads.AdView 。

您可以在官方developer site (click) 上阅读有关将 Admob SDK 迁移到 Google Play 服务的更多信息

编辑：顺便说一句，您必须将 Admob-Banner 布局代码移动到 LinearLayout 下方，否则它将不可见。
