How to get position of the element of arrayadapter

Imagine that i have a list with a ArrayAdapter like this:

When I long pressed Ubuntu I will go to the Context Menu

Well, my question is how I can get the position in arrayadapter of Ubuntu, when I long pressed and I go to the context menu?

Thanks in advance.

Check out the Creating Menus Dev Guide section Creating a Context Menu.

public boolean onContextItemSelected(MenuItem item){
   AdapterView.AdapterContextMenuInfo contextMenuInfo = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo();
   // ...
}

AdapterView.AdapterContextMenuInfo

If you are able to get the item, you can get the position using getPosition(T Item) which is detailed here and is invoked from an ArrayAdapter.
