ListView onItemClickListener throws null pointer on scrolling

I have a list view where in there are 2 text view places next to each other. Now, this list will have around more than 100 items in it displaying around 10 items in a single page.

Now, as I scroll down the list for all the positions say from position 12 to how much ever it might be, view returns as null.

When I looked for this, got some results of getFirstVisiblePosition(); etc. How ever, I am not very clear on this.

Could any be able to tell me how can I solve this?

Here is my code,

  listview.setOnItemClickListener(new OnItemClickListener() {
     @Override
    public void onItemClick(AdapterView<?> arg,View view, int pos, long arg3) {

         View parentView = (View) view.getParent();
         parentView = listview.getChildAt(pos);
        if (null != parentView) {
                TextView dupid, dupdesc;
                dupid = ((TextView) parentView.findViewById(R.id.dupitemId));
                dupdesc = ((TextView) parentView.findViewById(R.id.dupitemIdDesc));
                String duplicateId = dupid.getText().toString();
                String duplicateDesc = dupdesc.getText().toString();
           }

         }
    });

When I scroll down say to 20 position,

this line 

   parentView = listview.getChildAt(pos);

throws me null.

enter image description here

Can any one help me in figuring out?

Isn't this all you need to do?

listview.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg,View view, int pos, long arg3) {
        TextView dupid, dupdesc;
        dupid = ((TextView) view.findViewById(R.id.dupitemId));
        dupdesc = ((TextView) view.findViewById(R.id.dupitemIdDesc));
        String duplicateId = dupid.getText().toString();
        String duplicateDesc = dupdesc.getText().toString();
    }
});
