從mysql中的json請求創建自定義列表視圖

Question

嘿傢伙我試圖在我的應用程序中創建一個自定義ListView，通過json請求加載數據fdrom mysql數據庫。我使用的

android.R.id.simple_list_item_1 

，但現在我已經創建了具有2個textviews的名稱和價格我自己的自定義XML文件。 我的代碼是

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; 
    } 

我想在TextView的1和價格的TextView 2 提前顯示股票的名稱的任何幫助將welcomed.Thanks！

你應該嘗試這樣

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);
