  boolean bulkflag = false;
  ListView reportslistview = (ListView) findViewById(android.R.id.list);
  public class MyAdapter extends SimpleAdapter {
    //private List<Table> tables;
    SharedPreferences prefs;
    private Activity activity;
    String val = "";

    //@SuppressWarnings("unchecked")
    public MyAdapter(Activity context, List<? extends Map<String, String>> tables, int resource, String[] from,
            int[] to) {
        super(context, tables, resource, from, to);
        //this.tables = (List<Table>) tables;
        activity    =   context;
    }

    public View getView(final int position, final View convertView, ViewGroup parent) {
        View row = super.getView(position, convertView, parent);
        if (row == null) 
        {
            LayoutInflater inflater = (LayoutInflater) activity
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            row = inflater.inflate(R.layout.reports_list, null);
        }       

        final CheckBox cBox=(CheckBox)row.findViewById(R.id.cb1);
        if(bulkflag)
        {
            cBox.setVisibility(View.VISIBLE);
        }
        else
        {
            cBox.setVisibility(View.GONE);
        }
        cBox.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {

                if(cBox.isChecked())
                {
                    selectedIds.add(recIdArr.get(reportslistview.getPositionForView(cBox)));
                    //System.out.println("position "+reportslistview.getPositionForView(cBox));
                }
                else
                {
                    selectedIds.remove(recIdArr.get(reportslistview.getPositionForView(cBox)));
                }
            }
        });
        return row;
    }
}

Checking ====>

 for(int i=0;i<selectedIds.size();i++)
 {
    System.out.println("delete multiple"+selectedIds.size()+" "+Integer.parseInt(selectedIds.get(i)));
 }

Declare selectedIds as a global variable
