Question

JSON數組通過名稱獲得JSON對象我有JSON解析這樣

名稱

• 品牌

• 值RECOM

  • 值
  • 價值b

• MPN

• 值RECOM
  • 值的
  • 值b

我可以顯示在列表視圖中該值（品牌和MPN）。我想如果點擊品牌，它會在列表中顯示價值推薦（值爲a和b）。如果我點擊mpn，它也會在列表中顯示來自名稱2的值推薦值（值a和b）。任何人都可以給我建議？感謝

這是我的JSON解析

array (
    'features' => 
    array (
    'Recommendations' => 
     array (
     'id' => 
     'NameRecommendation' => 
     array (
      0 => 
      array (
      'Name' => 'Brand', 
      ),  
      'ValueRecommendation' => 
      array (
       0 => 
       array (
       'Value' => 'Unbranded/Generic', 
       ), 

       1 => 
       array (
       'Value' => 'Canon', 
       ), 

       2 => 
       array (
       'Value' => 'Nikon', 
       ), 

      ), 
    1 => 
      array (
      'Name' => 'MPN', 
      ), 
       'ValueRecommendation' => 
      array (
       0 => 
       array (
       'Value' => 'mpn1', 
       ), 

       1 => 
       array (
       'Value' => 'aas', 
       ), 

       2 => 
       array (
       'Value' => 'aab', 
       ), 

Answer 1

檢查這個url 並與-name

Answer 2

jsonobject讀取的總數據可以在JSONArray對象閱讀本

這裏是例子

JSONArray jsonArr = new JSONArray(jsonStr); // this is you string as formatted in json array if not parse by this construct it will throw the jsonparseexception 

現在通過迭代器遍歷此json的每個對象

for(int i=0;i<jsonArr.length();i++){ 
    JSONObject jsonObj = jsonArr.get(i).getJsonObject("value recom"); 
    String a = jsonObj.getString("a"); // here is your data for a object 
    String b = jsonObj.getString("b"); // here is your data for b object 
} 

Answer 3

當使用谷歌gson。

var getRowData = 
[{ 
    "dayOfWeek": "Sun", 
    "date": "11-Mar-2012", 
    "los": "1", 
    "specialEvent": "", 
    "lrv": "0" 
}, 
{ 
    "dayOfWeek": "Mon", 
    "date": "", 
    "los": "2", 
    "specialEvent": "", 
    "lrv": "0.16" 
}]; 

    JsonElement root = new JsonParser().parse(request.getParameter("getRowData")); 
    JsonArray jsonArray = root.getAsJsonArray(); 
    JsonObject jsonObject1 = jsonArray.get(0).getAsJsonObject(); 
    String dayOfWeek = jsonObject1.get("dayOfWeek").toString(); 

使用上的ListView傑克遜

JsonFactory f = new JsonFactory(); 
       ObjectMapper mapper = new ObjectMapper(); 
      JsonParser jp = f.createJsonParser(getRowData); 
      // advance stream to START_ARRAY first: 
      jp.nextToken(); 
      // and then each time, advance to opening START_OBJECT 
     while (jp.nextToken() == JsonToken.START_OBJECT) { 
      Map<String,Object> userData = mapper.readValue(jp, Map.class); 
      userData.get("dayOfWeek"); 
      // process 
      // after binding, stream points to closing END_OBJECT 
     }
