sticky row in listview in activity

Question

Just one row in my listview should be sticky .Not sections or section with alphabets in stickyheaders.I really appreciate any help w.r.t listview sticky one row within activity and not fragment.How do I do that ? I really appreciate any help.Thanks in Advance. Using code like :

class MyAsyncTask extends
        AsyncTask<String, Integer, ArrayList<HashMap<String, String>>> {

    // Hashmap for ListView
    ArrayList<HashMap<String, String>> UploadsList = new ArrayList<HashMap<String, String>>();

    @Override
    protected void onPreExecute() {
        // Showing progress dialog before sending http request
        pDialog = new ProgressDialog(this);
        pDialog.setMessage("Please wait..");
        pDialog.setIndeterminate(true);
        pDialog.setCancelable(false);
        pDialog.show();        }

    @Override
    protected ArrayList<HashMap<String, String>> doInBackground(
            String... params) {

        // Creating JSON Parser instance
        JSONParser jParser = new JSONParser();

        // getting JSON string from URL
        JSONObject json = jParser.getJSONFromUrl(url);

        try {
            // Getting Array of Uploads
            uploads = json.getJSONArray(TAG_UPLOADS);

            // looping through All Uploads
            for (int i = 0; i < uploads.length(); i++) {
                JSONObject c = uploads.getJSONObject(i);

                // Storing each json item in variable
                String id = c.getString(TAG_ID);
                String name = c.getString(TAG_NAME);
                String date = c.getString(TAG_DATE);

                // creating new HashMap
                HashMap<String, String> map = new HashMap<String, String>();

                // adding each child node to HashMap key => value
                map.put(TAG_ID, id);
                map.put(TAG_NAME, name);
                map.put(TAG_DATE, date);

                // adding HashList to ArrayList
                UploadsList.add(map);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

        return UploadsList;
    }

    @Override
    protected void onPostExecute(ArrayList<HashMap<String, String>> result) {

        pDialog.dismiss();

        ListAdapter adapter = new SimpleAdapter(this, result,
                R.layout.list_item,
                new String[] { TAG_NAME, TAG_ID, TAG_DATE }, new int[] {
                R.id.name, R.id.id, R.id.date });

        setListAdapter(adapter);
    }
}

I wrote this code for Json... Hope this will solve your puzzle.. And you like this...

            data = new ArrayList<String>();
            for (int ak = 1; ak < 20; ak++) {
                data.add("Row " + ak);

            ListView lv = (ListView) findViewById(R.id.listView1);

        }

        class CustomAdapter extends ArrayAdapter<String> {

            public CustomAdapter(Context context, int resource) {

            }

            @Override
            public View getView(int position, View convertView, ViewGroup parent) {

                TextView tv = new TextView(getApplicationContext());
                tv.setTextSize(20);
                tv.setText(getItem(position + 1));
                return tv;
            }

            @Override
            public int getCount() {

                return data.size() - 1;
            }

            @Override
