You could just keep track of the previous delete button, since only one is allowed. In the long click listener you can delete the previous button and create a new one.

ImageButton prevDelete = null;

...

list.setOnItemLongClickListener (new OnItemLongClickListener() {
  public boolean onItemLongClick(AdapterView parent, View view, int position, long id)      {
        deleteButton(prevButton); // check if not null in the function
        prevDelete = createButton(view); // draw button at view
        return true;
  }
});

You have probably already implemented the functions createButton and deleteButton.

Try this,

Assuming you're using a Adapter for the list...

    final ImageButton prevButton=null;
    row.setOnLongClickListener(new OnLongClickListener() {          
        @Override
        public boolean onLongClick(View arg0) {
            ImageButton currButton=row.findViewById(R.id.<button_id>);
            currButton.setVisibility(View.VISIBLE);
            if(prevButton!=null)
                prevButton.setVisibility(View.gone);
            prevButton=currButton;
            return true;
        }
    });

The question is pretty confusing... But from what understood i figure out you need to detect a long press on a list item. Have you tried the AdapterView.OnItemLongClickListener.

somelist.setOnItemLongClickListener (new OnItemLongClickListener() {
  public boolean onItemLongClick(AdapterView parent, View view, int position, long id) {
    //do your stuff of showing\hiding button here...
  }
});
