Dibujé un cajón de navegación personalizado con ListView y encabezado, pero cuando desplazo la Lista, la casilla de verificación en la Lista se desmarca.

En segundo lugar, cuando hago clic en el botón de reinicio en la parte del encabezado, quiero que todas las casillas de verificación en la Vista de lista no estén marcadas. He intentado esto para que funcione, pero no pude encontrar ninguna solución.

Los fragmentos son

public class NavigationDrawer extends Fragment{
   @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.filter_navigation_drawer, container,false);
        drawerListView= ( ListView ) view.findViewById( R.id.listDrawer );
        drawerListView.setOnItemClickListener(new FilterDrawerItemClickListener());

        dataList.add(new FilterDrawerItem("sample1",true));
        dataList.add(new FilterDrawerItem("sample2",true));
        dataList.add(new FilterDrawerItem("sample3",true));
        dataList.add(new FilterDrawerItem("sample4",true));
        dataList.add(new FilterDrawerItem("sample5",true));
        dataList.add(new FilterDrawerItem("sample2",true));
        dataList.add(new FilterDrawerItem("sample2",true));
        dataList.add(new FilterDrawerItem("sample2",true));
        dataList.add(new FilterDrawerItem("sample2",true));

        adapter = new FilterCustomDrawerAdapter(getActivity(), R.layout.drawer_filter,dataList,drawerStatus);
        drawerListView.setAdapter(adapter);
        adapter.getFilterList();

        resetBtn = (TextView)view.findViewById(R.id.filterby_reset);
        if(resetBtn != null){
            resetBtn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    application.setFilterStatus("reset");
                    for(int i=0; i<dataList.size(); i++){
                       dataList.get(i).setCheckBoxId(false);
                    }
                    adapter.notifyDataSetChanged();
                    // this.onCreateView();
                }
            });
        }

        return view;
    }
}

FilterCustomDrawerAdapter.java

    Context context;

    List<Integer> filterList = new ArrayList<Integer>();
    DrawerStatus drawerStatus;
    StataApplication application = StataApplication.getInstance();

    HashMap<Integer, Boolean> checked;   // newly added code

    public FilterCustomDrawerAdapter(Context context, int layoutResourceID,
                                     List<FilterDrawerItem> listItems,DrawerStatus drawerStatus) {

    }

    @Override

        // TODO Auto-generated method stub

        final FilterDrawerItemHolder drawerHolder;
        View view = convertView;

        if (view == null) {
            LayoutInflater inflater = ((Activity) context).getLayoutInflater();
            drawerHolder = new FilterDrawerItemHolder();

            view = inflater.inflate(layoutResID, parent, false);
            drawerHolder.ItemName = (TextView) view.findViewById(R.id.drawer_filterName);
            drawerHolder.checkBox = (CheckBox) view.findViewById(R.id.drawer_cbox);

            view.setTag(drawerHolder);
        } else {
            drawerHolder = (FilterDrawerItemHolder) view.getTag();
        }

        FilterDrawerItem dItem = (FilterDrawerItem) this.drawerItemList.get(position);

        drawerHolder.ItemName.setText(dItem.getItemName());
        TextView resetView = (TextView)view.findViewById(R.id.filterby_reset);
        CheckBox checkBox = (CheckBox) view.findViewById(R.id.drawer_cbox);

        // Newly added code
        Boolean isChecked = checked.get(position);
        checkBox.setChecked(isChecked == null ? false : isChecked);

      // if(application.getFilterStatus() != null) {
           if(checkBox.isChecked()){
               drawerHolder.checkBox.setChecked(false);
           }
      // }

        checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
                if (isChecked) {
                    filterList.add(new Integer(position));
                    checked.put(position, true);
                } else {
                    filterList.remove(new Integer(position));
                    checked.put(position, false);
                }
            }
        });

        drawerHolder.checkBox.setTag(position);
        Log.d("FILTER_LIST_SIZE",String.valueOf(filterList.size()));

        return view;
    }

    private static class FilterDrawerItemHolder {
        TextView ItemName;
        CheckBox checkBox;
    }

    public List<Integer> getFilterList(){
        return filterList;
    }
}

En la imagen a continuación, cuando desplazo la lista y si selecciono la casilla de verificación sample1 y sample 2, se desmarcará al desplazarse. y también al hacer clic en el botón de reinicio en el encabezado, quiero que todas mis casillas estén desmarcadas ... No puedo hacer que esto funcione ...

 resetBtn.setOnClickListener(new View.OnClickListener() {

                        adapterDataList.get(i).setCheckBoxId(false);
