android searchview setOnActionExpandListener on Honeycomb 3.2

Question

I'm developing an app for Android 3.2 and greater with android-support-v4. I need to implement OnActionExpandListener for "intercept" when SearchView in the actionbar is expanded and when is collapsed. My code for Android 4.0 and higher it's ok, but for 3.2 no.

menu.xml

<item android:id="@+id/menu_search"
    android:title="@string/menu_search"
    android:icon="@android:drawable/ic_menu_search"
    android:showAsAction="collapseActionView|always"
    android:actionViewClass="android.widget.SearchView" />

MyActivity.java

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.reader, menu);

    final MenuItem searchMI = menu.findItem(R.id.menu_search);
    if(searchView == null) {
        //searchView = (SearchView) searchMI.getActionView();
        searchView = (SearchView) MenuItemCompat.getActionView(searchMI);
        searchView.setOnQueryTextListener(this);
        searchView.setOnSuggestionListener(this);
        searchView.setOnCloseListener(new OnCloseListener() {

            @Override
            public boolean onClose() {
                //some code
                return false;
            }
        });
    }


    int currentapiVersion = android.os.Build.VERSION.SDK_INT;
    if (currentapiVersion <= android.os.Build.VERSION_CODES.HONEYCOMB_MR2) {
        MenuItemCompat.setShowAsAction(searchMI, MenuItemCompat.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW | MenuItemCompat.SHOW_AS_ACTION_ALWAYS);
        MenuItemCompat.setOnActionExpandListener(searchMI, new OnActionExpandListener() {

            /* (non-Javadoc)
             * @see android.support.v4.view.MenuItemCompat.OnActionExpandListener#onMenuItemActionExpand(android.view.MenuItem)
             */
            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                Toast.makeText(getApplicationContext(), "onMenuItemActionExpand", Toast.LENGTH_SHORT).show();
                return true;
            }

            /* (non-Javadoc)
             * @see android.support.v4.view.MenuItemCompat.OnActionExpandListener#onMenuItemActionCollapse(android.view.MenuItem)
             */
            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                Toast.makeText(getApplicationContext(), "onMenuItemActionExpand", Toast.LENGTH_SHORT).show();
                return true;
            }
        });
    } else {
        searchMI.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {

            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                Toast.makeText(getApplicationContext(), "MenuItem#onMenuItemActionExpand", Toast.LENGTH_SHORT).show();
                return true;
            }

            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                Toast.makeText(getApplicationContext(), "MenuItem#onMenuItemActionExpand", Toast.LENGTH_SHORT).show();
                return true;
            }
        });
    }
}

Why, for Honeycomb, methods of listener is not invoked?

Thank you so much.

For MenuItemCompat.setOnActionExpandListener to work you should add "collapseActionView" added in the menu item - for example -

<item android:id="@+id/action_search"
          android:icon="@drawable/ic_action_search"
          android:title="@string/action_search"
          app:showAsAction="ifRoom|collapseActionView"
          app:actionViewClass="android.support.v7.widget.SearchView" />

And in the onCreateOptionsMenu you can use it this way -

MenuItemCompat.setOnActionExpandListener(menu_search,
            new OnActionExpandListener()
            {
                @Override
                public boolean onMenuItemActionCollapse(MenuItem item)
                {
                    // Do something when collapsed
                    return true; // Return true to collapse action view
                }

                @Override
                public boolean onMenuItemActionExpand(MenuItem item)
                {
                    // Do something when expanded
                    return true; // Return true to expand action view
                }
            });
