        ArrayList<String> valuesList = new ArrayList<String>();
        ArrayList<Planet> planetList = listAdapter.planetList;
        for (int i = 0; i < planetList.size(); i++) {
            Planet planet = planetList.get(i);
            if (planet.isChecked()) {
                valuesList.add(planet.getName());
                responseText.append("\n" + planet.getName());
            }
        }
        System.out.println("Selected Values List Size : "+valuesList.size());
        String[] valueArray = new String[valuesList.size()];
        for(int j=0;j<valuesList.size();j++){
            valueArray[j]=valuesList.get(j);
        }
        System.out.println("Selected Values Array Size : "+valueArray.length);
