Prevent ListView Item refresh when adding another Item dynamically using Android

问题

I am using BaseAdapter to bind Custom ListView. And I am adding Items dynamically. Each Item contains TextView, EditText, Spinner. It is working fine. But now issue is that if user selects any value from Spinner, add some data in EditText and then if he/she adds new item then it clears all values of filled up data.

So, I want to prevent this refresh of already added Items when add new Item. How to do this ?

My Code :

ArrayList<HashMap<String, String>> aaName = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map = null;

map = new HashMap<String, String>();
map.put("Name", Name value);
aaName.add(map);
NameAdapter nameAdapter = new NameAdapter(getActivity(), aaName);
lvName.setAdapter(nameAdapter);

public class NameAdapter extends BaseAdapter {

    public View getView(int position, View convertView, ViewGroup parent) {
    View vi = convertView;
    if (convertView == null)
        vi = inflater.inflate(R.layout.chiefcomment_view, null);

    TextView tvName = (TextView) vi.findViewById(R.id.tvName);
    Spinner spnTime = (Spinner) vi.findViewById(R.id.spnTime);
    EditText etSpecification = (EditText) vi.findViewById(R.id.etSpecification);

    HashMap<String, String> name = new HashMap<String, String>();
    name = data.get(position);

    tvName.setText(name.get("Name"));

    // Time Spinner...
    ArrayList<String> Time = new ArrayList<String>();
    for (int i = 1; i <= 100; i++) {
        Time.add(String.valueOf(i));
    }
    aaTime = new ArrayAdapter<String>(activity, R.layout.small_spinner_view, Time);
    spnTime.setAdapter(aaTime);

    return vi;
    }
}
