    @OnClick(R.id.group_delete)    
    void deleteGroup() {

    AlertDialog.Builder dialog4 = new AlertDialog.Builder(PreviewActivity.this);

    LayoutInflater inflater2 = getLayoutInflater();
    View convertView2 = (View) inflater2.inflate(R.layout.alert_dialog_delete_group, null);
    dialog4.setView(convertView2);

    ListView listView2 = (ListView) convertView2.findViewById(R.id.listViewGroup);

    final List<Item> groupList = this.getGroup();

    CustomAdapter listAdapter2 = new CustomAdapter(getBaseContext(), groupList);

    // listAdapter2.notifyDataSetChanged();

    convertView2.setTag(dialog4);

 //   SparseBooleanArray sp = listView2.getCheckedItemPositions();

    listView2.setOnItemClickListener((AdapterView<?> adapterView, View view, int position, long l) -> {
        // Get user selected item.
        Object itemObject = adapterView.getAdapter();

        Item itemDto = (Item) itemObject;

        CheckBox itemCheckbox = (CheckBox) convertView2.findViewById(R.id.checkMark5);


        listAdapter2.setCheckedItem(position);





    });


    ImageView delete = (ImageView) convertView2.findViewById(R.id.del_group);
    delete.setOnClickListener((View view) -> {

        CheckBox itemCheckbox = (CheckBox) convertView2.findViewById(R.id.checkMark5);

        Iterator<String> it = listAdapter2.getCheckedItems().values().iterator();
        for (int i=0;i<listAdapter2.getCheckedItems().size();i++){
            //Do whatever
       //                String result = "";

       //                ArrayList<String> resultList = new ArrayList<String>();
       //                for (int y = 0; y < resultList.size(); y++) {
       //                        result += String.valueOf(resultList.get(i)) + "\n";
       //                    }

    //                    }


                listAdapter2.getItem(Integer.parseInt(it.next()));
            }

        //   List<Item> resultList = listAdapter2.getCheckedItems();

    //                    for (int i = 0; i < resultList.size(); i++) {
    //                        result += String.valueOf(resultList.get(i)) + "\n";
    //                    }

    //                    listAdapter2.getCheckedItemPositions().toString();
    //

Item Class:

Custom Adapter :::

public class CustomAdapter extends BaseAdapter {

    return convertView;
