ActionBar Sherlock涵蓋所有屏幕

Question

我剛剛在我的Android應用程序中實現了Sherlock的ActionBar。

問題是：正如您從圖像中看到的那樣，加載到MainActivity中的Google Maps API v2的SupportMapFragment完全覆蓋了actionBar。我已經做了一些測試：加載一個不同的片段，例如一個簡單的SherlockListFragment，但結果完全相同，並且不要設置setListNavigationCallbacks（因爲問題可能是我的自定義SpinnerAdapter），但actionBar總是覆蓋所有屏幕，甚至沒有任何文字。

從我的應用程序的一些代碼：

Main.java

public class Main extends SherlockFragmentActivity implements ActionBar.OnNavigationListener 
{ 
private static final String STATE_SELECTED_NAVIGATION_ITEM = "selected_navigation_item"; 
private FragmentMappa fMappa; 
private FragmentLinee fLinee; 
private FragmentAtmInforma fAtm; 

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    fMappa = new FragmentMappa(); 
    fLinee = new FragmentLinee(); 
    fAtm = new FragmentAtmInforma(); 
    setContentView(R.layout.activity_main); 

    int IdFixedHeader = -1; 
    Utils.ImpostaActionBar(IdFixedHeader, this); 

    getSupportFragmentManager().addOnBackStackChangedListener(getListener()); 
    getSupportFragmentManager().beginTransaction().replace(R.id.MainContainer, fMappa).commit(); 
    new downloadUtils().execute(0, this, true); 
} 

Utils.java

public static void ImpostaActionBar(int IdFixedHeader, SherlockFragmentActivity Act, String StrFixHead) { 
    // Set up the action bar to show a dropdown list. 
    ActionBar actionBar = Act.getSupportActionBar(); 
    actionBar.setDisplayShowTitleEnabled(false); 
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST); 
    ArrayList<VoceListaMenuNav> Voci = new ArrayList<VoceListaMenuNav>(); 
    Voci.add(new VoceListaMenuNav(Act.getString(R.string.title_mappa), R.drawable.btn_show_map)); 
    Voci.add(new VoceListaMenuNav(Act.getString(R.string.title_linee), R.drawable.btn_compass_tilt)); 
    Voci.add(new VoceListaMenuNav(Act.getString(R.string.title_percorso), R.drawable.fer)); 
    Voci.add(new VoceListaMenuNav(Act.getString(R.string.title_preferiti), R.drawable.btn_show_map)); 
    Voci.add(new VoceListaMenuNav(Act.getString(R.string.title_AtmInforma), R.drawable.btn_show_map)); 
    // Set up the dropdown list navigation in the action bar. 
    actionBar.setListNavigationCallbacks(new AdapterListaMenuNav(Act.getSupportActionBar().getThemedContext(), Voci, IdFixedHeader, StrFixHead), (OnNavigationListener) Act); 
    actionBar.setSelectedNavigationItem(IdFixedHeader); 
} 

styles.xml

<resources xmlns:android="http://schemas.android.com/apk/res/android"> 
<style name="AppTheme" parent="Theme.Sherlock.Light.DarkActionBar"> 
    <!-- All customizations that are NOT specific to a particular API-level can go here. --> 
    <item name="android:windowActionBarOverlay">true</item> 
    <item name="android:windowActionModeOverlay">true</item> 
    <item name="android:actionBarStyle">@style/ActionBar</item> 
</style> 

<color name="GrigioSemiTrasp">#af000000</color> 

    <style name="ActionBar" parent="Widget.Sherlock.Light.Spinner.DropDown.ActionBar"> 
    <item name="android:background">@color/GrigioSemiTrasp</item> 
</style> 
</resources> 

我的自定義適配器：

public class AdapterListaMenuNav extends BaseAdapter 
{ 
@Override 
public View getView(int arg0, View arg1, ViewGroup parent) { 
    View rowView = arg1; 
    if (rowView == null) 
    { 
     rowView = inflater.inflate(R.layout.list_item_menu_nav_top, null); 
     ViewHolderListaGenerica viewHolder = new ViewHolderListaGenerica(); 
     viewHolder.Titolo = (TextView) rowView.findViewById(R.id.ListaMenuNavTitolo); 
     rowView.setTag(viewHolder); 
    } 
    if (FixedHeader == -1) 
    { 
     ViewHolderListaGenerica holder = (ViewHolderListaGenerica)rowView.getTag(); 
     VoceListaMenuNav f = LisVoci.get(arg0); 
     holder.Titolo.setText(f.Titolo); 
     return rowView; 
    } 
    else 
    { 
     ViewHolderListaGenerica holder = (ViewHolderListaGenerica)rowView.getTag(); 
     VoceListaMenuNav f = LisVoci.get(FixedHeader); 
     holder.Titolo.setText(f.Titolo); 
     return rowView; 
    } 
} 

Context Ctx; 
ArrayList<VoceListaMenuNav> LisVoci; 
LayoutInflater inflater; 
int FixedHeader; 

public AdapterListaMenuNav(Context Cont, ArrayList<VoceListaMenuNav> ListaVoci, int IdFixedHeader, String StrFxHeader) 
{ 
    LisVoci = ListaVoci; 
    inflater = (LayoutInflater)Cont.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    Ctx = Cont; 
    FixedHeader = IdFixedHeader; 
} 

@Override 
public int getCount() { 
    return LisVoci.size(); 
} 

@Override 
public Object getItem(int arg0) { 
    return null; 
} 

@Override 
public long getItemId(int arg0) { 
    return 0; 
} 

@Override 
public View getDropDownView(int arg0, View arg1, ViewGroup arg2) { 
    View rowView = arg1; 
    if (rowView == null) 
    { 
     rowView = inflater.inflate(R.layout.list_item_menu_nav, null); 
     ViewHolderListaGenerica viewHolder = new ViewHolderListaGenerica(); 
     viewHolder.Titolo = (TextView) rowView.findViewById(R.id.ListaMenuNavTitolo); 
     viewHolder.Immagine = (ImageView) rowView.findViewById(R.id.ListaMenuNavImage); 
     rowView.setTag(viewHolder); 
    } 

    ViewHolderListaGenerica holder = (ViewHolderListaGenerica)rowView.getTag(); 
    VoceListaMenuNav f = LisVoci.get(arg0); 
    holder.Titolo.setText(f.Titolo); 
    holder.Immagine.setImageResource(f.IdImage); 
    return rowView; 
} 

}

我在努力尋找出任何東西，終於可以回答自己。問題來自於ABS風格的繼承。正確的代碼是：

<style name="ActionBar" parent="Widget.Sherlock.Light.ActionBar"> 
.... 
</style>
