random checkbox getting checked when scrolling down the list view

I'm trying to implement CheckBox with OnClickListener . The examples available are all on OncheckedchangeListener .

Once I select one CheckBox , and I scroll down the ListView , random CheckBox are getting checked. no idea why?

 holder.checkbox.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                    CheckBox checkbox = (CheckBox) v;
                    ClaimList claimList = (ClaimList) checkbox.getTag();
                    claimList.setChecked(checkbox.isChecked());
                }

You need to use ViewHolder in ListView Adapter also need to add boolean flag for selected item in getter setter Class

Check this link : Listview with Checkbox

I had the same problem. I solved it by overriding this two method in adapter class.

@Override
public int getViewTypeCount() {
          return getCount();
}

@Override
public int getItemViewType(int position) {

 return position;
}

Hope this helps!
