public class MyListAdapter implements ListAdapter {
    MainActivity mainActivity;
    private ViewHolder holder;
    private String[] scoresToUpdate=new String[1000] ;
    public MyListAdapter(MainActivity mainActivity) {
        this.mainActivity=mainActivity;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return 20;
    }

    @Override
    public Object getItem(int arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public long getItemId(int arg0) {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public int getItemViewType(int arg0) {
        // TODO Auto-generated method stub

    }

    @Override
    public View getView(int arg0, View convertView, ViewGroup arg2) {
        if (convertView == null) {

            holder = new ViewHolder();

            LayoutInflater vi = (LayoutInflater)    
            mainActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = vi.inflate(R.layout.element_in_game, null);

            holder.scoreToUpdate = (EditText) convertView
                    .findViewById(R.id.txt);


            convertView.setTag(holder);

        } else {

            holder = (ViewHolder) convertView.getTag();

        }
        final int tmp_position=arg0;
       holder.scoreToUpdate.setText(scoresToUpdate[tmp_position]);
       holder.scoreToUpdate.addTextChangedListener(new TextWatcher() {

                @Override

                        int before, int count) {
                    scoresToUpdate[tmp_position] = s.toString();
                }

                public void beforeTextChanged(CharSequence s, int start,
                        int count, int after) {

                }

                @Override
