Apps JSON send string value

[shien]

Hi i am trying to make view that shows only your name but after you click it it shows email and gender. This data was put in JSON file. But now it shows everything and after clicking it also shows everything. Any ideas how to change it?

ArrayList<HashMap<String,String>> contactList = new ArrayList<HashMap<String,String>>();
        
        JSONParser jParser = new JSONParser();
        JSONObject json = jParser.getJSONFromUrl(url);
        try{
        	contacts = json.getJSONArray(TAG_CONTACTS);
        	for(int i = 0; i < contacts.length(); i++)
        	{
        		JSONObject c = contacts.getJSONObject(i);
        		
        		String id = c.getString(TAG_ID);
        		String vardpav = c.getString(TAG_NAME);
        		String email = c.getString(TAG_EMAIL);
        		String lytis = c.getString(TAG_GENDER);
        		String nuoroda = c.getString(TAG_LINK);
        		
        		HashMap<String,String> map = new HashMap<String, String>();
        		
        		map.put(TAG_ID, id);
        		map.put(TAG_NAME, vardpav);
        		map.put(TAG_EMAIL, email);
        		map.put(TAG_GENDER, lytis);
        		map.put(TAG_LINK, nuoroda);
        		contactList.add(map);
        	}
        } catch (JSONException e) {
        	e.printStackTrace();
        }
        ListAdapter adapter = new SimpleAdapter(this, contactList,R.layout.list_item,
        		new String[] {TAG_NAME, TAG_EMAIL, TAG_GENDER, TAG_LINK}, new int[] { R.id.name, R.id.email, R.id.gender, R.id.link});
        
        setListAdapter(adapter);
        
        ListView lv = getListView();
        lv.setOnItemClickListener(new OnItemClickListener(){
        	public void onItemClick(AdapterView<?> parent, View view, int position, long id){
        		String name = ((TextView)view.findViewById(R.id.name)).getText().toString();

        		Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
        		in.putExtra(TAG_NAME, name);
        		in.putExtra(TAG_EMAIL, email);
        		in.putExtra(TAG_GENDER, lytis);
        		in.putExtra(TAG_LINK, nuoroda);
        		startActivity(in);

		    String str;
		    while ((str = in.readLine()) != null) {
		        txtFile.setText(str);
		    	// str is one line of text; readLine() strips the newline character(s)
		    }
		    in.close();
		} catch (MalformedURLException e) {

			System.out.println("CHACHACHA");
