            holder.txtoptiontitle.setText(arrListViewoption_title
                    .get(position));
            holder.txtsubtitle.setText(arrlistViewsub_title.get(position));

            if (value.equals(arrListViewoption_type.get(position)
                    .toString().trim())) {
                checkitem.setVisibility(View.VISIBLE);
                holder.btn_radio.setVisibility(View.GONE);

            }

            checkitem
                    .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

                        @Override

                                boolean isChecked) {
                            // int getPosition = (Integer) view.getTag();
                            // list.get(getPosition).setSelected(view.isChecked());

                            if (view.isChecked()) {

                                checkboxvalue.add(arrlistViewsub_title
                                        .get(position).toString().trim());

                            }

                            Log.i(this.toString(),
                                    "Item" + checkboxvalue.size());

                        }
                    });

            holder.btn_radio
                    .setOnCheckedChangeListener(new OnCheckedChangeListener() {

                        @Override
                        public void onCheckedChanged(
                                CompoundButton buttonView, boolean isChecked) {
                            // TODO Auto-generated method stub

                                // Action Doing here

                            }

Using the convertview is usefull for performancce and fast scrolling but can lead to that kind of problem.

you should reset any set values from the convert view before reusing it. In your case :

boolean wasItemChecked = checkboxvalue.contains(arrlistViewsub_title.get(position).toString().trim());
checkItem.setChecked(wasItemChecked );

if the checkItem state has changed, it reset it to its true state according to the datasource state.

hope that helps.
