i'm defining my own list adapter and i want an image inside it to be shown OR hidden based on a value what i've noticed that its always invisible or visible disregarding the value

Here's my code , this code is inside the getView method

singleRow=data.get(position);
     readit = singleRow.getRead();
    Log.i("readit","" + readit );
    //NotificationID=singleRow.getId();
    holder.title.setText(singleRow.getAttach_title());
    holder.date.setText( singleRow.getAttach_created());
    holder.dueDate.setVisibility(ImageView.INVISIBLE);
    holder.course.setText(singleRow.getCourse_title());

    if(readit==1)
            {
                //holder.read.setImageResource(IGNORE_ITEM_VIEW_TYPE);
                holder.read.setVisibility(ImageView.INVISIBLE);
            }
            else
             {
              holder.read.setImageResource(R.drawable.unread);
             }
