How to build ActionBar with collapsible search view with single action item visible, when search view is expanded? To be more descriptive, this is what I need:

enter image description here Note that there are other menu items and android:uiOptions="splitActionBarWhenNarrow" is defined in AndroidManifest.xml.

I tried to set up custom search item layout:

menu.xml

<item
    android:id="@+id/menu_search"
    android:actionLayout="@layout/actionbar_search"
    android:icon="@drawable/action_search"
    android:showAsAction="always|collapseActionView"
    android:title="@string/search" />

actionbar_search.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="right"
    android:orientation="horizontal" >

    <com.actionbarsherlock.widget.SearchView
        android:id="@+id/search_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:iconifiedByDefault="false"
        android:queryHint="@string/search_hint" />

    <ImageButton
        android:id="@+id/add_item"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        style="@style/Widget.Sherlock.ActionButton"
        android:src="@drawable/content_new"/>

</LinearLayout>

But by default search view takes all available width and button is not visible. I don't know how to force SearchView to fill all available space between app icon and menu item. All I found is android:maxWidth property, but

android android-actionbar searchview
