Xamarin searchview OnActionExpandListener

Issue

I am struggling finding how to implement this Java code in Xamarin. I have tried searchView.Close += delegate { }; but it doesn't work.

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;
        }
    });

Solution

Thanks for your answer, it didn't work at first, I had an exception

This is not supported use menuitemcompat.setonactionexpandlistener()

I had to do this instead

At the top of my file :

using MenuItemCompat = Android.Support.V4.View.MenuItemCompat;

In OnCreateOptionsMenu() when I create the search view.

IMenuItem searchItem = menu.FindItem(Resource.Id.searchItem);
MenuItemCompat.SetOnActionExpandListener(searchItem, new ExpandListener(this));

And finally the listener class

class ExpandListener : Java.Lang.Object, MenuItemCompat.IOnActionExpandListener
{
    Context context;

    public ExpandListener(Context pContext)
    {
        context = pContext;
    }
    public bool OnMenuItemActionCollapse(IMenuItem item)
    {
        //MyStuff with context
        return true;
    }

    public bool OnMenuItemActionExpand(IMenuItem item)
    {
        //Stuff
        return true;
    }
}
