爲什麼TabView和MapView不能一起工作？

我有一個簡單的tabView，有2個選項卡。在第一個標籤中，我顯示了一些listview，第二個我想顯示地圖。但是，當我嘗試是我的應用程序壞了。爲什麼TabView和MapView不能一起工作？

還有就是我TabView的代碼：

public class MainActivity extends TabActivity { 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     Resources res = getResources(); 

     TabHost tabHost = getTabHost(); 
     Intent i = getIntent(); 

     Intent intentList = new Intent().setClass(this, ListActivity.class); 
     intentList.putExtra(StartActivity.SEARCH_KEY, i.getStringExtra(StartActivity.SEARCH_KEY)); 
     TabHost.TabSpec tabSpecList = tabHost.newTabSpec("List").setContent(intentList).setIndicator(res.getString(R.string.list_tab)); 

     Intent intentMap = new Intent().setClass(this, MapPlaceActivity.class); 
     TabHost.TabSpec tabSpecMap = tabHost.newTabSpec("Map").setContent(intentMap).setIndicator(res.getString(R.string.map_tab)); 

     tabHost.addTab(tabSpecList); 
     tabHost.addTab(tabSpecMap); 
     tabHost.setCurrentTab(0); 
    } 

}

當我運行應用程序，我有一個很錯誤：

07-27 14:12:23.676: ERROR/dalvikvm(19527): Could not find class 'com.example.MapPlaceActivity', referenced from method com.example.MainActivity.onCreate

     at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:607) 
     at dalvik.system.NativeStart.main(Native Method)

但是我真的有MapPlaceActivity，有一個從它的代碼：

public class MapPlaceActivity extends MapActivity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.map); 
     MapView mapView = (MapView) findViewById(R.id.mapview); 
     mapView.setBuiltInZoomControls(true); 
    } 

    @Override 
    protected boolean isRouteDisplayed() { 
     return false; //To change body of implemented methods use File | Settings | File Templates. 
    } 
}

還有我的佈局文件（map.xml）：

<?xml version="1.0" encoding="utf-8"?> 
<com.google.android.maps.MapView 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/mapview" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:clickable="true" 
     android:apiKey="Hiden key" 
/>

我的清單文件：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
      package="com.example" 
      android:versionCode="1" 
      android:versionName="1.0"> 
    <uses-sdk android:minSdkVersion="8"/> 
    <uses-permission android:name="android.permission.INTERNET" /> 
    <uses-library android:name="com.google.android.maps"/> 
    <application android:label="@string/app_name"> 

     <activity android:name=".StartActivity" 
        android:label="@string/app_name" 
        android:theme="@android:style/Theme.Light.NoTitleBar"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN"/> 
       <category android:name="android.intent.category.LAUNCHER"/> 
      </intent-filter> 
     </activity> 
     <activity android:name=".Pref" 
        android:label="@string/settings_label" 
        > 
     </activity> 
     <activity android:name=".MainActivity" 
        android:theme="@android:style/Theme.Light.NoTitleBar"> 
     </activity> 
     <activity android:name=".MapPlaceActivity" 
        android:label="@string/map_tab" 
        android:theme="@android:style/Theme.Light.NoTitleBar"> 
     </activity> 
     <activity android:name=".ListActivity" 
      android:theme="@android:style/Theme.Light.NoTitleBar"> 
     </activity> 

    </application> 
</manifest>

發表您的清單文件，你可以給下面的標籤！ – KMI 2012-07-27 11:23:02

應該加在裏面.... – KMI 2012-07-27 11:29:52

非常感謝。它有幫助。 – Andrew 2012-07-27 11:31:22

我想你需要添加使用庫線的應用標籤內的清單文件。

此外，如果你想

<supports-screens 
android:anyDensity="true" 
android:resizeable="true" 
android:largeScreens="true" />
