How to get checkbox value in the nested Click structure.

I have a ListView with CheckBox on it. and i am using Custom Adapter to populate the ListView. And I am binding the checkbox data using viewHolder

private static class PlanetArrayAdapter extends ArrayAdapter<Planet>
    {

        private LayoutInflater inflater;

        public PlanetArrayAdapter(Context context, List<Planet> planetList)
        {
            super(context, R.layout.simplerow, R.id.rowTextView, planetList);
            // Cache the LayoutInflate to avoid asking for a new one each time.
            inflater = LayoutInflater.from(context);
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent)
        {
            // Planet to display
            Planet planet = (Planet) this.getItem(position);

            // The child views in each row.
            CheckBox checkBox;


            // Create a new row view
            if (convertView == null)
            {
                convertView = inflater.inflate(R.layout.simplerow, null);

                // Find the child views.

                checkBox = (CheckBox) convertView.findViewById(R.id.CheckBox01);

                // Optimization: Tag the row with it's child views, so we don't
                // have to
                // call findViewById() later when we reuse the row.
                convertView.setTag(new PlanetViewHolder(textView, checkBox));

                // If CheckBox is toggled, update the planet it is tagged with.
                checkBox.setOnClickListener(new View.OnClickListener()
                {
                    public void onClick(View v)
                    {
                        CheckBox cb = (CheckBox) v;
                        Planet planet = (Planet) cb.getTag();
                        planet.setChecked(cb.isChecked());
                    }
                });
            }
            // Reuse existing row view
            else
            {
                // Because we use a ViewHolder, we avoid having to call
                // findViewById().
                PlanetViewHolder viewHolder = (PlanetViewHolder) convertView
                        .getTag();
                checkBox = viewHolder.getCheckBox();

            }

            // Tag the CheckBox with the Planet it is displaying, so that we can
            // access the planet in onClick() when the CheckBox is toggled.
            checkBox.setTag(planet);

            // Display planet data
            checkBox.setChecked(planet.isChecked());


            return convertView;
        }

    }

But the Problem is I am showing this as TabHost in vertical orientation. And one of the tab click i am showing this Listview.

So I am unable to get the click event in click event.

Or Suggest any better way to get this done.
