After programmatically checking checkboxes in recyclerview in android, other random checkboxes getting checked automatically

I have one recyclerview in my android application, listing some records with checkboxes. While selecting records by programatically checking checkboxes, I found that once checked records, other records from recyclerview automatically get selected. And sometimes the previously selected checkbox get unselected automatically

adapter_for_group.java

public class adapter_for_group extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private LayoutInflater layoutInflater;
static List<GetandSet> grpinbuiltnme;
static List<GetandSet> linknmed;
private static Context context;
public static ArrayList<String> listcheck = new ArrayList<>();

public adapter_for_group(Context context, List<GetandSet> links, List<GetandSet> nmelist) {
    this.context = context;
    layoutInflater = LayoutInflater.from(context);
    this.grpinbuiltnme = nmelist;
    this.linknmed = links;
}


@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = layoutInflater.inflate(R.layout.url_recycler, parent, false);
    adapter_for_group.Holder holder = new adapter_for_group.Holder(v);
    return holder;
}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    final adapter_for_group.Holder holder1 = (adapter_for_group.Holder) holder;
    final GetandSet getandSet = linknmed.get(position);
    holder1.name.setText(getandSet.getName());
holder1.checkedclickListener(new Group.ItemCheckedClickListenered() {
        @Override
        public String onCheckedClick(View view, int position) {
            if(listcheck.contains(linknmed.get(position).getName())/*&& dsaf.listcheck1.contains(linklst.get(position).getName())*/){
                listcheck.remove(linknmed.get(position).getName());
            }
            else {
                listcheck.add(linknmed.get(position).getName());
            }
            return null;
        }
    });
}

@Override
public int getItemCount() {
    return linknmed.size();
}

    TextView name;

        for (GetandSet getandSet1 : linknmed) {
            ch[i] = new CheckBox(context);
            ch[i].setId(getandSet1.get_id());
            ll.addView(ch[i]);
            mCheckBoxes.add(ch[i]);
            i++;
        }
        itemView.setTag(itemView);

        try {
            if (grpinbuiltnme != null) {

                            }
                        }
                    }
                }
            }
        } catch (Exception e) {
