How to display custom view in ActionBar?

Question

I want to display custom search in actionbar (I'm using ActionBarSherlock for that).

I got that:

But I want make custom layout (edittext field) to occupy the entire available width.

I've implemented custom layout as suggested here.

There is my custom layout search.xml:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     style="?attr/actionButtonStyle"     android:layout_width="fill_parent"     android:layout_height="match_parent"     android:layout_gravity="fill_horizontal"     android:focusable="true" >      <FrameLayout         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_gravity="center_vertical|fill_horizontal" >          <EditText             android:id="@+id/search_query"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:layout_gravity="left|center"             android:background="@drawable/bg_search_edit_text"             android:imeOptions="actionSearch"             android:inputType="text" />          <ImageView             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_gravity="right|center_vertical"             android:src="@drawable/ic_search_arrow" />      </FrameLayout>  </LinearLayout> 

And in MyActivity:

ActionBar actionBar = getSupportActionBar(); actionBar.setDisplayHomeAsUpEnabled(true); actionBar.setDisplayShowCustomEnabled(true); actionBar.setDisplayShowTitleEnabled(false); actionBar.setIcon(R.drawable.ic_action_search);  LayoutInflater inflator = (LayoutInflater) this .getSystemService(Context.LAYOUT_INFLATER_SERVICE); View v = inflator.inflate(R.layout.search, null);  actionBar.setCustomView(v); 

How can I make custom layout to occupy all the available width of actionBar?

Help, please.

There is a trick for this. All you have to do is to use RelativeLayout instead of LinearLayout as the main container. It's important to have android:layout_gravity="fill_horizontal" set for it. That should do it.
