Multi_checkboxes

In activity called  AttendanceActivity.class,

public static int check_all_status = -1;

//methos called in onCreate()
    private void onClickSetAllAttendance() {
        selectAll.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                if (selectAll.isChecked()) {
                    check_all_status = 1;
                    listAdapter.notifyDataSetChanged();
                } else {
                    check_all_status = 0;
                    listAdapter.notifyDataSetChanged();
                }
            }
        });

    }



And my  adapter class is bellow,

public class InteractiveArrayAdapter extends ArrayAdapter<Model> {

    private final List<Model> list;
    private final Activity context;

    public InteractiveArrayAdapter(Activity context, List<Model> list) {
        super(context, R.layout.list_items_attendance_payment, list);
        this.context = context;
        this.list = list;
    }

    static class ViewHolder {
        protected TextView text;
        protected CheckBox checkbox;

    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        View view = null;
        if (convertView == null) {
            LayoutInflater inflator = context.getLayoutInflater();
            view = inflator.inflate(R.layout.list_items_attendance_payment, null);
            final ViewHolder viewHolder = new ViewHolder();
            viewHolder.text = (TextView) view.findViewById(R.id.name);
            viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
            viewHolder.checkbox
                    .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

                        @Override
                        public void onCheckedChanged(CompoundButton buttonView,
                                boolean isChecked) {
                            AttendanceActivity.listMember.get(position).setSelected(isChecked);
                            Model element = (Model) viewHolder.checkbox
                                    .getTag();
                            element.setSelected(buttonView.isChecked());
                        }
                    });
            view.setTag(viewHolder);
            viewHolder.checkbox.setTag(list.get(position));
        } else {
            view = convertView;
            ((ViewHolder) view.getTag()).checkbox.setTag(list.get(position));
        }
        ViewHolder holder = (ViewHolder) view.getTag();
        holder.text.setText(list.get(position).getName());

        if (AttendanceActivity.check_all_status==1) {
            holder.checkbox.setChecked(true);
        }
        else if(AttendanceActivity.check_all_status==0){
            holder.checkbox.setChecked(false);

        }
        else if(holder.checkbox.isChecked())
        {
            AttendanceActivity.check_all_status= 1;
        }
        else if(!holder.checkbox.isChecked())
        {
            AttendanceActivity.check_all_status= 0;
        }
        else{
            holder.checkbox.setChecked(list.get(position).isSelected());
        }

        return view;
    }
}
