            // TODO Auto-generated method stub

            View vi = convertView;
            final int as=position;
            if (convertView == null) { // if it's not recycled, initialize some
                // attributes
                LayoutInflater  inflater = (LayoutInflater) activity
                        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                vi = inflater.inflate(R.layout.grid_item, null);
                holder = new ViewHolder();

                holder.textheader = (TextView) vi.findViewById(R.id.item1);
                holder.textcpu = (TextView) vi.findViewById(R.id.item2);
                holder.text_modified_date = (TextView) vi.findViewById(R.id.item4);
                holder.text_cpu = (TextView) vi.findViewById(R.id.item3);
                holder.text_checkbox=(CheckBox)vi.findViewById(R.id.checkBox1);
                vi.setTag(holder);

                holder.text_checkbox.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        if (holder.text_checkbox.isClickable()) {

Try below code

public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        View vi = convertView;
        final int as=position;
        if (convertView == null) { // if it's not recycled, initialize some
            // attributes
            LayoutInflater  inflater = (LayoutInflater) activity
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            vi = inflater.inflate(R.layout.grid_item, null);
            holder = new ViewHolder();

            holder.textheader = (TextView) vi.findViewById(R.id.item1);
            holder.textcpu = (TextView) vi.findViewById(R.id.item2);
            holder.text_modified_date = (TextView) vi.findViewById(R.id.item4);
            holder.text_cpu = (TextView) vi.findViewById(R.id.item3);
            holder.text_checkbox=(CheckBox)vi.findViewById(R.id.checkBox1);
            vi.setTag(holder);

        } else {
            holder = (ViewHolder) vi.getTag();
        }          


             holder.text_checkbox.setOnCheckedChangeListener(new OnCheckedChangeListener() 
             {          
              public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)      
                {                                  
                if(isChecked)
                {
                      // do your stuff
                      itemChecked.set(as, true);
                        packages=as;
                }
                else
                {
                      // do your stuff
                      itemChecked.set(as, false);
                }       

        }
    });

if(itemChecked.size() != 0 && itemChecked.get(position))
        holder.text_checkbox.setChecked(true);
    else
        holder.text_checkbox.setChecked(false);
