Changing sherlock action bar menu item background Color in android

Question

I'm using sherlocklibrary to show action bar in my application,it works fine but when i put background image for the header a black area appears at the right side (See the snapshot). How can change the background color of the menu button or at least fill parent the header image. And i'm updating this image at run time according to the user choice. This is my title bar layout.

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/headerLinear"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >


    <ImageView
        android:id="@+id/logo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
         />

    <TextView
        android:id="@+id/title"
        style="@style/titleStyle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_toLeftOf="@+id/logo"
        android:maxLength="30"
        android:ellipsize="end"
        android:text="@string/login_en" />

</RelativeLayout>

And i put this code in my activity:

            BitmapDrawable bg = (BitmapDrawable)  getResources().getDrawable(R.drawable.bg_striped_split);

    getSupportActionBar().setBackgroundDrawable(bg);

    LayoutInflater inflater = LayoutInflater.from(this);
    View customView = inflater.inflate(R.layout.title_bar, null);

    RelativeLayout header = (RelativeLayout) customView.findViewById(R.id.headerLinear);



    header.setBackgroundDrawable(R.drawable.header);
