Return empty row in Custom ArrayAdapter?

when my ListView is being filled by a custom Array Adapter, I check for a certain parameter in the current list item, and if it is false, I want to return an empty row. At the moment, I am doing this by inflating an empty xml file, but that creates ugly list item dividers when a number of items should not be shown, and is obviously not the best way ;-)!

    if (list.get(position).equals("i-dont-want-this-in-the-list-view")){
        View empty=inflater.inflate(R.layout.empty_row, parent, false);
        return(empty);
    }

I have tried to return "null", but it clearly expects a View to be returned. Is there anything I could do without having to filter the list that is being used for the ListView beforehand (I want to keep it intact as I am doing other things with it, too).

Thanks,

Nick

What's about:

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
   //use a global Array to set the rows visible/hidden and return empty rows
   if(disArray[position] == false) return new View(getContext()); 

   ... // continue with your getView() implementation
   return convertView;
}

to update the ListView use

adapter.notifyDataSetChanged();

View.Gone will give u empty list row. try using layout params and set to zero value like this:

FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(0,0); viewholder.programRow.setLayoutParams(layoutParams);

Layoutparams should be used as according to parent viewgroup used

What're in the rows that aren't empty? Images can be replaced by empty, transparent pngs and text views can be set to "", etc.

To fix the issue of line dividers, remove the line dividers from the ListView and put your own in inside the individual items.
