Group count is not displaying correctly in listview

Question

I am showing the listview of the group name with count of how many contacts are there in the group.But its not showing correctly.while adding contact to the group ,for one contacts its affecting other group count also and its increasing double also.

Its not showing the correct count of the group,i am checking this only in 2.2 version,because 4.2 this code is working perfectly,but its not working in lower versions

  public void onResume()
             {
              super.onResume();
               getgroup=getAvailableContactGroups();
                  getcount();

                  gAdapter = new GroupAdapter(this, getgroup);

            lv.setAdapter(gAdapter);
    }

class GroupAdapter extends BaseAdapter 
        {  
            private SparseBooleanArray mCheckStates;
            ArrayList<String> group; 


            LayoutInflater mInflater;
            TextView tv,tv1;
            CheckBox cb;
            GroupAdapter(FirstScreenGroupActivity groupActivity, ArrayList<String> group)
            {
                mCheckStates = new SparseBooleanArray(group.size());
                mInflater = (LayoutInflater)FirstScreenGroupActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                this.group = group;


            }
            @Override
            public int getCount() {
                // TODO Auto-generated method stub
                return group.size();
            }

            @Override
            public Object getItem(int position) {
                // TODO Auto-generated method stub
                return position;
            }

            @Override

            }

                    View vi=convertView;
                    if(convertView==null)

                    vi = mInflater.inflate(R.layout.show_groups, null); 
                    tv= (TextView) vi.findViewById(R.id.textView2);
                    tv1= (TextView) vi.findViewById(R.id.groupcount);


                    try
                    {
                    tv.setText(group.get(position));

                    tv1.setText("(" + String.valueOf(groupcount.get(position)) + ")");
                    }
                    catch(IndexOutOfBoundsException e)
                    {
                        Toast.makeText(FirstScreenGroupActivity.this, "catch", 1000).show();
                    }
