我刚刚在我的 Android 应用程序中实现了 Sherlock 的 ActionBar。

问题是：从图片中可以看出，我在 MainActivity 中加载的 Google Maps API v2 SupportMapFragment 完全被 actionBar 覆盖。我已经做了一些测试：加载一个不同的片段，例如一个简单的 SherlockListFragment，但结果是完全一样的，并且不要设置 setListNavigationCallbacks（因为问题可能是我的自定义 SpinnerAdapter）但 actionBar 总是涵盖所有屏幕，即使里面没有任何文字。

我的应用程序中的一些代码：

主.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);
}

实用程序.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);
}

样式.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>

我的自定义适配器：

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;
}

}

我努力寻找任何东西，终于可以回答自己了。问题出在 ABS 样式继承自什么。正确的代码是：

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