I am trying to display parsed jason data to listview

ListViewAdapterForAtomicListItemtype.java

public class ListViewAdapterForAtomicListItemtype extends BaseAdapter {

    // Declare Variables
    Context context;
    LayoutInflater inflater;
    ArrayList<HashMap<String, String>> data;
    HashMap<String, String> resultp = new HashMap<String, String>();

    public ListViewAdapterForAtomicListItemtype(Context context,
            ArrayList<HashMap<String, String>> arraylist) {
        this.context = context;
        data = arraylist;
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    public View getView(final int position, View convertView, ViewGroup parent) {
        // Declare Variables
        TextView name;

        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View itemView = inflater.inflate(R.layout.listview_item_for_atomic_list_item_type, parent, false);
        // Get the position
        resultp = data.get(position);

        // Locate the TextViews in listview_item.xml
        name = (TextView) itemView.findViewById(R.id.textView_id_atomic_list_item_type);

        // Capture position and set results to the TextViews
        name.setText(resultp.get(MainActivity.NAME));


        return itemView;
    }
}
