Hey guys i am trying to create a custom ListView in my application that loads data fdrom mysql database by json request. i used the

android.R.id.simple_list_item_1

but now i have created my own custom xml file which has 2 textviews for the name and the price. My code is

public void ListDrwaer() {
        List<Map<String, String>> stocksList = new ArrayList<Map<String, String>>();

        try {
            JSONObject jsonResponse = new JSONObject(jsonResult);
            JSONArray jsonMainNode = jsonResponse.optJSONArray("metoxes");
            TextView tv1 = (TextView)findViewById(R.id.textView1);
            TextView tv2 = (TextView)findViewById(R.id.textView2);

            for (int i = 0; i < jsonMainNode.length(); i++) {
                JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
                String name = jsonChildNode.optString("name");
                String price = jsonChildNode.optString("price");
                stocksList.add(createStockList(name, price));
            }


        } catch (JSONException e) {
            Toast.makeText(getApplicationContext(), "Error" + e.toString(),
                    Toast.LENGTH_SHORT).show();
        }
        String[] from = { "name", "price" };
        int[] to = { R.id.textView1, R.id.textView2 };

        SimpleAdapter simpleAdapter = new SimpleAdapter(this, stocksList,
                R.layout.list_item,
                from, to);
        listView.setAdapter(simpleAdapter);
    }

    private HashMap<String, String> createStockList(String name, String price) {
        HashMap<String, String> stockNameNo = new HashMap<String, String>();
        stockNameNo.put("name", name);
        stockNameNo.put("price", price);
        return stockNameNo;
    }

you should try like this

String[] from = { "name", "price" };
int[] to = { R.id.textView1, R.id.textView2 };

SimpleAdapter adapter = new SimpleAdapter(this, list,
    R.layout.list_item, from, to);
setListAdapter(adapter);

see this example for more information
