Access ActionView on Android ActionBar

I have a problem getting the actionview from a menu item used in an actionbar. I'm using Actionbarsherlock for compatibility reasons.

I'm using this code in onCreateOptionMenu:

        menu.add("Search")
        .setIcon(R.drawable.ic_search)
        .setActionView(R.layout.collapsible_edittext)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);

The ActionView i set is just an EditText from XML which will "fill_parent" in terms of width. As i couldn't find a way to access this edittext to register an event handler i tried to inflate "R.layout.collapsible_edittext" in oncreateoptionsmenu (and later in onOptionsItemSelected) adding the result as acitonview. After i did this i could access the edittext but it didn't take the full width in my actionbar anymore after the icon was clicked.

Any hints how to access the ActionView properly?

EditText layout

<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:singleLine="true"
          android:hint="Search"/>

Code

 private EditText search;


  private TextWatcher filterTextWatcher = new TextWatcher() {
        public void afterTextChanged(Editable s) {
        }

        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }

        public void onTextChanged(CharSequence s, int start, int before, int count) {
            //... your logic here    
        }
    };

@Override
    public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
        menu.add(0, 3, 3, R.string.ac_search  ).setIcon(R.drawable.ic_action_search).setActionView(R.layout.action_search).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
        return super.onCreateOptionsMenu(menu);
    }


  @Override
    public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item) {
        switch (item.getItemId()){

            case 3:
                search = (EditText) item.getActionView();
                search.addTextChangedListener(filterTextWatcher);
                break;

        }
        return true;
    }
