【问题描述】：

我正在尝试使用 WebView 实施 AdMob 广告。对于我的一生，我无法展示任何东西，即使在日志中也是如此。几乎就像根本没有调用广告一样 - 我的 AdMob 帐户没有显示任何请求。起初我认为 WebView 只是占用了布局中的所有空间，但现在我又开始怀疑自己了，因为我没有看到任何与广告相关的 LogCat 输出。

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
      android:orientation="vertical"
      android:layout_
      android:layout_>
      <com.google.ads.AdView android:id="@+id/adView"
                 android:layout_
                 android:layout_
                 ads:adUnitId="[myIDishere]"
                 ads:adSize="BANNER"
                 ads:testDevices="[myhashishere]"
                 ads:loadAdOnCreate="true"/>
  <WebView
        android:id="@+id/webView"
        android:layout_
        android:layout_ />

  </LinearLayout>

然后是我的主要活动：

public class MainActivity extends Activity 



//StartServicesCheck


private boolean checkPlayServices() 
      int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
      if (status != ConnectionResult.SUCCESS) 
        if (GooglePlayServicesUtil.isUserRecoverableError(status)) 
          showErrorDialog(status);
         else 
          Toast.makeText(this, "This device is not supported.", 
              Toast.LENGTH_LONG).show();
          finish();
        
        return false;
      
      return true;
     

    void showErrorDialog(int code) 
      GooglePlayServicesUtil.getErrorDialog(code, this, 
          REQUEST_CODE_RECOVER_PLAY_SERVICES).show();
    

    static final int REQUEST_CODE_RECOVER_PLAY_SERVICES = 1001;

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) 
      switch (requestCode) 
        case REQUEST_CODE_RECOVER_PLAY_SERVICES:
          if (resultCode == RESULT_CANCELED) 
            Toast.makeText(this, "Google Play Services must be installed.",
                Toast.LENGTH_SHORT).show();
            finish();
          
          return;
      
      super.onActivityResult(requestCode, resultCode, data);
    



//EndServicesCheck

private WebView mWebview ;

@Override
public void onBackPressed() 
    if(mWebview.canGoBack() == true)
        mWebview.goBack();
    else
        super.onBackPressed();
    



public class BannerExample extends Activity 
      @Override
      public void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Look up the AdView as a resource and load a request.
        AdView adView = (AdView)this.findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);
      
    


@Override
public void onCreate(Bundle savedInstanceState) 

    super.onCreate(savedInstanceState);

    mWebview  = new WebView(this);

    mWebview.getSettings().setjavascriptEnabled(true); // enable javascript
    mWebview.getSettings().setBuiltInZoomControls(true);

    if(android.os.Build.VERSION.SDK_INT >= 11) 
        mWebview.getSettings().setDisplayZoomControls(false);
    

    final Activity activity = this;

    mWebview.setWebViewClient(new WebViewClient() 
        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) 
            Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
        
    );

    mWebview .loadUrl("[webpagehere]");
    setContentView(mWebview );


    mWebview.setWebViewClient(new WebViewClient()

        @Override
        public void onPageFinished(WebView view, String url) 
            // TODO Auto-generated method stub
            super.onPageFinished(view, url);
            mWebview.scrollTo(681, 100);
        

    
    );

我的编码本身有问题吗？我有点倾向于这种方式，因为我没有看到请求或日志输出。

【问题讨论】：

等一下，你的代码搞砸了。您已经在 MainActivity 中定义了 Banner 活动？只创建一个活动..

【参考方案1】：

将WebView 更改为以下内容。你的AdView 被WebView 隐藏了：

<WebView
    android:id="@+id/webView"
    android:layout_
    android:layout_
    android:weight="1" />

我还建议将 AdView 的宽度设置为 match_parent 和 adSize 为 "SMART_BANNER" SMART_BANNER 广告会根据设备的方向和宽度自动调整大小。

编辑

我刚刚浏览了您的代码。它有很多小错误。将其更改为以下内容：

public class MainActivity extends Activity 



//StartServicesCheck

@Override
public void onCreate(Bundle savedInstanceState) 

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
AdView adView = (AdView)this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);
mWebview  = (WebView) findViewById(R.id.webview);

mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
mWebview.getSettings().setBuiltInZoomControls(true);

if(android.os.Build.VERSION.SDK_INT >= 11) 
    mWebview.getSettings().setDisplayZoomControls(false);


final Activity activity = this;

mWebview.setWebViewClient(new WebViewClient() 
    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) 
        Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
    
);

mWebview .loadUrl("[webpagehere]");
setContentView(mWebview );


mWebview.setWebViewClient(new WebViewClient()

    @Override
    public void onPageFinished(WebView view, String url) 
        // TODO Auto-generated method stub
        super.onPageFinished(view, url);
        mWebview.scrollTo(681, 100);
    


);




private boolean checkPlayServices() 
  int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
  if (status != ConnectionResult.SUCCESS) 
    if (GooglePlayServicesUtil.isUserRecoverableError(status)) 
      showErrorDialog(status);
     else 
      Toast.makeText(this, "This device is not supported.", 
          Toast.LENGTH_LONG).show();
      finish();
    
    return false;
  
  return true;
 

void showErrorDialog(int code) 
  GooglePlayServicesUtil.getErrorDialog(code, this, 
      REQUEST_CODE_RECOVER_PLAY_SERVICES).show();


static final int REQUEST_CODE_RECOVER_PLAY_SERVICES = 1001;

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
  switch (requestCode) 
    case REQUEST_CODE_RECOVER_PLAY_SERVICES:
      if (resultCode == RESULT_CANCELED) 
        Toast.makeText(this, "Google Play Services must be installed.",
            Toast.LENGTH_SHORT).show();
        finish();
      
      return;
  
  super.onActivityResult(requestCode, resultCode, data);




//EndServicesCheck

private WebView mWebview ;
@Override
public void onBackPressed() 
    if(mWebview.canGoBack() == true)
        mWebview.goBack();
    else
        super.onBackPressed();
    

PS：对不起，缩进搞砸了：P

【讨论】：

我刚刚进行了所有这些更改，但我仍然没有看到它:( 在 logcat 我仍然没有看到任何提及尝试加载的广告.. :(

感谢您的帮助，非常感谢。因此，我实施了您的更改，应用程序立即崩溃。 Logcat 声明：06-18 11:36:54.380: E/AndroidRuntime(27310): Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.ads.AdView" on path: DexPathList[[zip file "/data/app/com.iamthesquidward.ferris-14.apk"],nativeLibraryDirectories=[/data/app-lib/com.iamthesquidward.ferris-14, /vendor/lib, /system/lib]]。我假设它找不到任何 AdMob 引用，即使我尝试将 jar 复制到库并引用 Play Services SDK

确保您已正确添加 Google Play 服务，并将您的 adview 替换为 Play 服务中的一个，即 com.google.android.gms.ads.AdView。检查此链接：developers.google.com/mobile-ads-sdk/docs/admob/fundamentals
