You can set an expand/collapse listener on the MenuItem like this:

menuItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
    @Override
    public boolean onMenuItemActionExpand(MenuItem item) {
        return true;
    }

    @Override
    public boolean onMenuItemActionCollapse(MenuItem item) {
        return true;
    }
});

This listener was introduced with API level 14, so for backwards compatibility you have to use the v4 support library. If you do then you have to set the expand/collapse listener like this:

MenuItemCompat.setOnActionExpandListener(this.searchItem, new MenuItemCompat.OnActionExpandListener() {

    @Override
    public boolean onMenuItemActionExpand(MenuItem item) {
        return true;
    }

    @Override
    public boolean onMenuItemActionCollapse(MenuItem item) {
        return true;
    }
});
