TabView와 MapView가 함께 작동하지 않는 이유는 무엇입니까?

Question

2 탭이있는 간단한 tabView가 있습니다. 첫 번째 탭에서 몇 가지 listview를 보여주고, 두 번째로는지도를 보여주고 싶습니다. 하지만 내가하려고하면 내 앱이 고장났다. 내가 응용 프로그램을 실행하면 내가 그 오류의이

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); 
    } 

} 

:

내 tabview 코드가

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. 
    } 
}

하지만 난 정말 MapPlaceActivity을 가지고, 그것에서 코드가

내 레이아웃 파일 (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" 
/> 

내 매니페스트 파일 :

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
      package="com.example" 
      android:versionCode="1"

    <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"

       <category android:name="android.intent.category.LAUNCHER"/> 
      </intent-filter> 
     </activity> 
     <activity android:name=".Pref" 
        android:label="@string/settings_label"

     <activity android:name=".MainActivity" 
        android:theme="@android:style/Theme.Light.NoTitleBar">

     <activity android:name=".MapPlaceActivity" 
        android:label="@string/map_tab"

     <activity android:name=".ListActivity"

    </application> 
</manifest> 

Answer 1

난 당신이 매니페스트 파일에서 응용 프로그램 태그 내부의 용도를 라이브러리 줄을 추가해야 할 것 같아요. 당신이

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