Android ActionBar图标和向上指示器

Question

尝试显示操作栏向上指示器时，它会在图标旁边显示为白色空白方块。我有一个动作栏的自定义主题。我试图将背景设置为绿色，然后将图标与向上箭头设置

我的Styles.xml中的

<style name="Theme.Base" parent="@android:style/Theme.Holo">
<item name="android:background">@color/white</item>
<item name="android:windowBackground">@color/white</item>
<item name="android:actionBarStyle">@style/Theme.Base.ActionBar</item>

<style name="Theme.Base.ActionBar" parent="@android:style/Widget.Holo.ActionBar">
<item name="android:homeAsUpIndicator">@color/blue</item>
<item name="android:background">@color/green</item>
<item name="android:icon">@drawable/icon</item>

在我班级的顶部，我设置了主题

         [Activity(Label = "My Activity", Theme = "@style/Theme.Base", NoHistory = true)]
public class Login : Activity

在我的活动中

        #region ActionBar MENU
    /// <summary>
    /// Creating the menu
    /// </summary>
    /// <param name="menu">the menu to create</param>
    /// <returns>boolean</returns>
    public override bool OnCreateOptionsMenu(IMenu menu)
    {
        var inflater = MenuInflater;
        inflater.Inflate(Resource.Menu.MapItems, menu);

        ActionBar.SetDisplayShowHomeEnabled(true);
        ActionBar.SetDisplayHomeAsUpEnabled(true);
        ActionBar.SetHomeButtonEnabled(true);
        ActionBar.SetDisplayShowTitleEnabled(false);
        //Hide menu items you dont require
        menu.FindItem(Resource.Id.MyAccount).SetVisible(false);

        return base.OnCreateOptionsMenu(menu);
    }

    /// <summary>
    /// On Menu Item Click
    /// </summary>
    /// <param name="featureId">The feature Id</param>
    /// <param name="item">The item selected</param>
    /// <returns>boolean</returns>
    public override bool OnMenuItemSelected(int featureId, IMenuItem item)
    {
        switch (item.ItemId)
        {
            case (Constants.Home):
                StartNewActivity(typeof(Map.Map));
                break;
        }
        return base.OnMenuItemSelected(featureId, item);
    }

    #endregion

我无法改变颜色，但白色方格现在消失了。删除背景设置为白色有助于:-)并设置父主题

parent="@android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">


 <style name="Theme.Base" parent="@android:style/Theme.Holo">
<item name="android:windowBackground">@color/white</item>
<item name="android:actionBarStyle">@style/Theme.Base.ActionBar</item>

  <style name="Theme.Base.ActionBar" parent="@android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:homeAsUpIndicator">@color/blue</item>
<item name="android:background">@color/green</item>
<item name="android:titleTextStyle">@style/Theme.Base.ActionBar.TitleTextStyle</item>
