"Whack a checkbox" game with ListView

Programmer Question

I have a ListActivity that was originally using an ArrayAdapter. Each item in my ListView contains a checkbox.

I changed Adapters to a CursorAdapter. Everything is working fine except checkboxes are out of control. For example: When I click the checkbox in position 1, the checkbox in position 4 gets checked. If I click the checkbox in position 1 again, it will check (Ie: When I click the checkbox in position 1, if the checkbox in position 4 is not checked, the checkbox in position 4 will get checked; else, the checkbox in position 1 is checked). Unchecking checkboxes doesn't seem to show any weird behavior. Any ideas why?

Update: It's checking the checkbox backwards based on how many items are on screen. What I mean is, if there are 5 items visible, clicking the 1st one will check the 5th, clicking the 2nd one with check the 4th, clicking the 3rd one will check the 3rd one.

Here is a copy of my CursorAdapter

public class InboxAdapter extends CursorAdapter implements CheckBox.OnCheckedChangeListener {
    private int mCheckedCount = 0;

    public InboxAdapter(Context context, Cursor c) {
        super(context, c);
    }

    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if (buttonView.getId() == R.id.inbox_itemcheck) {
            if (isChecked) {
                mCheckedCount++;
            }
            else {
                mCheckedCount--;
            }
            ActivityInbox.this.showMultiPanel((mCheckedCount > 0) ? true : false);
        }
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        InboxHolder holder = (InboxHolder)view.getTag();

        if (holder.txtDate != null) {
            DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
            Date d = new Date(cursor.getInt(cursor.getColumnIndex("created_on")) * 1000L);
            holder.txtDate.setText(df.format(d));
        }
        if (holder.txtSubject != null) {
            holder.txtSubject.setText(cursor.getString(cursor.getColumnIndex("subject")));
            if (cursor.getInt(cursor.getColumnIndex("read")) == 0) {
                holder.txtSubject.setTypeface(null, Typeface.BOLD);
            }
            else {
                holder.txtSubject.setTypeface(null, Typeface.NORMAL);
            }
        }

        if(holder.txtSummary != null) {
            holder.txtSummary.setText(cursor.getString(cursor.getColumnIndex("summary")));
        }

        if (cursor.getInt(cursor.getColumnIndex("read")) == 0) {
            view.setBackgroundResource(R.drawable.selector_inbox_unread);
        }
        else {
            view.setBackgroundResource(R.drawable.selector_inbox_read);
        }

        if (holder.lMessageType != null) {
            if (cursor.getInt(cursor.getColumnIndex("read")) == 0) {
                holder.lMessageType.setVisibility(View.VISIBLE);
            }
            else {
                holder.lMessageType.setVisibility(View.INVISIBLE);
            }
        }
    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        LayoutInflater inflater = LayoutInflater.from(context);
        View v = inflater.inflate(R.layout.layout_inbox_item, parent, false);

        InboxHolder holder = new InboxHolder();
        holder.txtDate = (TextView) v.findViewById(R.id.inbox_item_date);
        holder.txtSubject = (TextView) v.findViewById(R.id.inbox_item_subject);
        holder.txtSummary = (TextView) v.findViewById(R.id.inbox_item_summary);
        holder.chkSelect = (CheckBox) v.findViewById(R.id.inbox_itemcheck);
        holder.lMessageType = (LinearLayout) v.findViewById(R.id.inbox_messagetype);

        v.setTag(holder);

        if (holder.chkSelect != null) {
            holder.chkSelect.setOnCheckedChangeListener(this);
        }
        return v;
    }

}
