如何在TextView和ImageView中顯示JSON值

Question

如何在imageview和textview中傳遞JSON值？

我的代碼如下包含三個ImageView（img11,img2,img3）和TextView（txt1,txt2,txt3）。我想在這些視圖中顯示我的JSONArray，其中包含名稱和URL。在我的代碼中沒有ListView。如何在我的TextView和ImageView中顯示我的JSON值？ http連接正常。問題在於解析JSON數組。

JSON：

/////////////// this is my json file//////////// 
    { 
    "worldpopulation": 
    [ 
     { 
     "rank":1, 
     "name": "BREAKFAST", 
     "url": "http://niel986.files.wordpress.com/2012/07/fast-food.jpg" 
     }, 
     { 
     "rank":2, 
     "name": "LUNCH ", 
     "url": "http://www.bubblews.com/assets/images/news/1107772406_1370520219.gif" 
     }, 
     { 
     "rank":3, 
     "name": "SUPPER", 
     "url": "http://2.bp.blogspot.com/_JU_j7jj5TjU/TSBQKRukf1I/AAAAAAAAAs8/X1w5_z6pjwQ 
/s1600/chicken-biryani.jpg" 
     } 
    ] 
} 

代碼：

ImageView img1 = (ImageView) findViewById(R.id.img1); 
    TextView txt1 = (TextView) findViewById(R.id.txt1); 

    ImageView img2 = (ImageView) findViewById(R.id.img2); 
    TextView txt2 = (TextView) findViewById(R.id.txt2); 

    ImageView img3 = (ImageView) findViewById(R.id.img3); 
    TextView txt3 = (TextView) findViewById(R.id.txt3); 

    MenuSelect = Utils.MenuSelect; 

    try { 
     HttpClient client = new DefaultHttpClient(); 
     HttpConnectionParams.setConnectionTimeout(client.getParams(), 15000); 
     HttpConnectionParams.setSoTimeout(client.getParams(), 15000); 
     HttpUriRequest request = new HttpGet(MenuSelect); 
     HttpResponse response = client.execute(request); 
     InputStream atomInputStream = response.getEntity().getContent(); 
     BufferedReader in = new BufferedReader(new InputStreamReader(atomInputStream)); 

     String line; 
     String str = ""; 
     while ((line = in.readLine()) != null) { 
      str += line; 
     } 

     JSONObject json = new JSONObject(str); 
     JSONArray data = json.getJSONArray("worldpopulation"); 

     String Name1 = data.getString("name"); 
     String url1 = person.getString("url"); 
     txt1.setText(Name1); 
     Bitmap bitmap = BitmapFactory.decodeStream((InputStream) new URL(
       url1).getContent()); 
     img1.setImageBitmap(bitmap); 

    } catch (MalformedURLException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     // IOConnect = 1; 
     e.printStackTrace(); 
    } catch (JSONException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    }

我認爲你需要這個

try { 
      JSONObject json = new JSONObject(str); 
      JSONArray data = json.getJSONArray("worldpopulation"); 
      JSONObject jsonOrder = (JSONObject)data.get(0); 
      txt1.setText (jsonOrder.getString("name")); 
      img1.setImageBitmap(/* decoded url input stream*/); 

      JSONObject jsonOrder = (JSONObject)data.get(1); 
      txt2.setText (jsonOrder.getString("name")); 
      img2.setImageBitmap(/* decoded url input stream*/); 

      JSONObject jsonOrder = (JSONObject)data.get(2); 
      txt3.setText (jsonOrder.getString("name")); 
      img3.setImageBitmap(/* decoded url input stream*/); 

     } catch (JSONException e) { 
      e.printStackTrace(); 
     }
