在Android中的選項卡中打開谷歌地圖不工作

Question

我想打開一個谷歌地圖應用程序，我在一個選項卡，但它沒有工作，它不斷收到強制關閉消息，當我運行它。我創建的主要活動文件[TabtestingActivity]它創建的標籤[HelloGoogleActivity類包含地圖代碼，不受標籤工作正常]

public class TabstestingActivity extends TabActivity { 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    Resources res = getResources(); 
    TabHost tabHost = getTabHost(); // The activity TabHost 
    TabHost.TabSpec spec; // Reusable TabSpec for each tab 
    Intent intent; // Reusable Intent for each tab 

     intent = new Intent().setClass(this, HelloGoogleActivity.class); 

    spec = tabHost.newTabSpec("tabOne"); 
    spec.setContent(intent); 
    spec.setIndicator("Tab One",res.getDrawable(R.drawable.tabselect)); 
    tabHost.addTab(spec); 
     tabHost.setCurrentTab(0); 
    } 
} 

如果我創建一個類只有一個文本它，它工作正常標籤，但是當我添加地圖類時，它停止工作。 這是我的main.xml：

<?xml version="1.0" encoding="utf-8"?> 
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@android:id/tabhost" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 
<LinearLayout 
android:orientation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" > 

<TabWidget 
android:id="@android:id/tabs" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" /> 
<FrameLayout 
android:id="@android:id/tabcontent  
android:layout_width="fill_parent" 
android:layout_height="fill_parent" > 

<RelativeLayout 
      xmlns:android="http://schemas.android.com/apk/res/android" 
      android:orientation="vertical" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"> 

    <com.google.android.maps.MapView 
    android:id="@+id/mapview" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:clickable="true" 
    android:apiKey="my key" 
    android:layout_weight="1"/> 
</RelativeLayout> 
</FrameLayout> 

</LinearLayout> 
</TabHost> 

有沒有問題，我的main.xml？

這是logcat的：

Answer 1

跟蹤是很清楚，

"10-26 00:47:10.207: ERROR/AndroidRuntime(303): Caused by: java.lang.IllegalArgumentException: MapViews can only be created inside instances of MapActivity." 

不能使用的MapView一個MapActivity之外。
