如何將所有json對象值存儲在arraylist中？

我有以下響應...從這個響應我解析bulkprice數組及其對象，現在我想要的是，我需要將所有minqty值存儲在一個arraylist中，並希望將所有這些值轉換爲整數。但我不能夠得到的..如何將所有json對象值存儲在arraylist中？

{"status":"success","clientproduct":[{"pid":"4","name":"kangan pair","unitprice":"1500","boxqty":"1","bulkprice":[{"minqty":"10","price":"1500"},{"minqty":"15","price":"1470"},{"minqty":"20","price":"1460"}]}]}

如果JSONObject的正確返回剛剛INT minimum_qty = jo.getInt（「minqty」）; – M090009

@ M090009然後我需要將它存儲在arraylist .. – chris

@chris你需要在一個arraylist中的所有minqty？ –

試試這個：

ArrayList<Integer> minqtyList = new ArrayList<Integer>(); 

JSONArray array = ck.getJSONArray(BULKPRICE_LIST); 
for (int i = 0; i < array.length(); i++) { 
    JSONObject row = array.getJSONObject(i); 
    int minqty = row.getInt("minqty"); 
    minqtyList.add(minqty); 
}

在你的代碼，你需要這樣的編輯這個部分：

bulkprice = ck.getJSONArray(BULKPRICE_LIST); 
allqtys=new ArrayList<String>(); // initialisation must be outside the loop 

for (int b=0 ; b < bulkprice.length(); b++){ 
    jo = bulkprice.getJSONObject(b); 
    minimum_qty=jo.getString("minqty"); 
    allqtys.add(minimum_qty); 

    System.out.println("All MinQuantitiy"+minimum_qty); 
    System.out.println("MinQuantitiy"+minimum_qty); 

    pricess=jo.getString("price");// here you'll get only the last value. otherwise you need to use a list, like you did with "minqty" 
    System.out.println("Box price "+pricess); 
}

我按照你的第二個代碼編輯..但它不顯示在arraylist – chris

你是什麼意思，「它顯示不在arraylist」？在你的日誌中，我可以看到* minqty *（10,15,20） – Rami

的3個值如果它解決了您的問題，請接受答案。而對於你的問題，我還不知道你想更新unitPrice從1500到1470的位置，如果你談論更新json，你需要用unitprice的新值重新創建客戶端產品JsonArray。 – Rami

我能蘇ggest您使用JSONArray您的JSON值，並通過他們向迭代：

String strJSON = ""; // your string goes here 
List<int> minqtys = new ArrayList<int>(); 

JsonReader rdr = Json.createReader(new StringReader(strJSON)) { 
    JsonObject obj = rdr.readObject(); 
    JsonArray results = obj.getJsonArray("bulkprice"); 
    for (JsonObject result : results.getValuesAs(JsonObject.class)) { 
     int minqty = Integer.parseInt(result.getString("minqty")); 
     minqtys.add(minqty); 
    } 
});

使用此代碼..

String json="{\"status\":\"success\",\"clientproduct\":[{\"pid\":\"4\",\"name\":\"kangan pair\",\"unitprice\":\"1500\",\"boxqty\":\"1\",\"bulkprice\":[{\"minqty\":\"10\",\"price\":\"1500\"},{\"minqty\":\"15\",\"price\":\"1470\"},{\"minqty\":\"20\",\"price\":\"1460\"}]}]}"; 

     String json1="{\"status\":\"success\",\"clientproduct\":[{\"pid\":\"4\",\"name\":\"kangan pair\",\"unitprice\":\"1500\",\"boxqty\":\"1\",\"bulkprice\":[{\"minqty\":\"10\",\"price\":\"1500\"},{\"minqty\":\"15\",\"price\":\"1470\"},{\"minqty\":\"20\",\"price\":\"1460\"}]},{\"pid\":\"6\",\"name\":\"Mala\",\"unitprice\":\"1500\",\"boxqty\":\"1\",\"bulkprice\":\"\"}]}"; 
     JSONObject jsonobj; 
     List<HashMap<String,String>> minqty_list=new ArrayList<HashMap<String,String>>(); 
     try { 
      jsonobj = new JSONObject(json1); 
      JSONArray client_product=jsonobj.getJSONArray("clientproduct"); 
      for(int i=0;i<client_product.length();i++) 
      { 
       JSONObject client_prod=client_product.getJSONObject(i); 
       try 
       { 
       JSONArray bulkprice=client_prod.getJSONArray("bulkprice"); 

       for(int j=0;j<bulkprice.length();j++) 
       { 
        HashMap<String, String> hs=new HashMap<String, String>(); 
        hs.put("bulk",bulkprice.getJSONObject(j).getString("minqty")); 
        minqty_list.add(hs); 
       } 
       }catch(JSONException e) 
       { 
        e.printStackTrace(); 
       } 
      } 
      System.out.println(minqty_list.toString()); 
     } catch (JSONException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     }

在上面的代碼更改爲

JSONArray bulkprice=client_prod.getJSONArray("bulkprice"); 
         for(int j=0;j<bulkprice.length();j++) 
         { 
          minqty_list.add(Integer.parseInt(bulkprice.getJSONObject(j).getString("minqty"))); 
         }

這個

try 
       { 
       JSONArray bulkprice=client_prod.getJSONArray("bulkprice"); 

       for(int j=0;j<bulkprice.length();j++) 
       { 
        HashMap<String, String> hs=new HashMap<String, String>(); 
        hs.put("bulk",bulkprice.getJSONObject(j).getString("minqty")); 
        minqty_list.add(hs); 
       } 
       }catch(JSONException e) 
       { 
        e.printStackTrace(); 
       }

它顯示org.json.JSONException：價值在類型java.lang.String bulkprice不能轉換爲JSONArray – chris

@chris我運行此代碼.. 。它爲你的json字符串工作...如果你正在嘗試用另一個json字符串plz發佈它... –

看到我編輯的代碼在問題..我編輯根據您的答案..它顯示..org.json。 JSONException：在java.lang.String類型的bulkprice處的值不能轉換爲JSONArray – chris

您可以輕鬆地做到這一點，利用Gson。

實施例：

List<CustomObject> myList = gson.fromJson(br, new 
TypeToken<List<CustomObject>>(){}.getType());
