將AdMob添加到Android應用程序：AdView

Question

我從最終將廣告投放到我的應用程序中脫穎而出（我認爲）。但是在1行發生崩潰。參見代碼：

public class ... extends ListActivity { 
/** Called when the activity is first created. */ 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    //setContentView(R.layout.main); 
    String[] rmenu = getResources().getStringArray(R.array.root_menu); 
    if (rmenu != null) { 
     setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, rmenu)); 
    } 
    setContentView(R.layout.main); 
    // 
    // Admob Code 
    // Create the adView 
    AdView av = new AdView(this, AdSize.BANNER, "publisher_id"); 
    // Lookup your LinearLayout assuming it’s been given 
    // the attribute android:id="@+id/mainLayout" 
    LinearLayout layout = (LinearLayout)findViewById(R.id.mainLayout); 
    // Add the adView to it 
    layout.addView(av); 
    // Initiate a generic request to load it with an ad 
    av.loadAd(new AdRequest()); 
} 

崩潰發生在行：layout.addView（av）;

我有一個adview添加到上面引用的佈局文件（mainLayout）。 我將添加XML代碼以及下面：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/mainLayout" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:background="#000000" > 

<adView 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:textColor="#FFFFFF" 
    android:text="Loading..." /> 

</LinearLayout> 

任何幫助，將不勝感激！或者只是一個手指在正確的方向。

固定。

好吧，我不再發生崩潰，我看到廣告在大約幾分鐘後彈出！

這是我做的。在本教程http://code.google.com/mobile/ads/docs/android/fundamentals.html您將看到第一步是將SDK JAR添加到您的項目中。我剛開始使用新的JAR文件，名爲「googleadmobadssdkandroid」。我仍然有可用的更老的下載，標題爲「admob-sdk-android_20101109」，並且我將BOTH JAR文件添加到我的項目中，上面的代碼現在可以工作。

Answer 1

你的LinearLayout似乎缺少在下面第二行：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res/your.package.name"

然後，讓你添加的Jar到您的構建路徑，並且它位於您的「庫」文件夾？

最後，我有時會忘記在res創建attrs.xml文件/值
