Question

私は、次のJSONを、持っている次のように

for (int i = 0; i < response.length(); i++) { 
        try { 
//      Toast.makeText(getActivity(), response.toString(), Toast.LENGTH_SHORT).show(); 
         JSONObject value = response.getJSONObject(i); 
         JSONObject statutory_mappings = value.getJSONObject("statutory_mappings"); 
         Iterator<String> keys = statutory_mappings.keys(); 
         while (keys.hasNext()) { 
          String key = (String) keys.next(); 
          JSONObject statMap = statutory_mappings.getJSONObject(key); 

          //iterate geography id's in case if there comes any necessity 
          JSONArray geography_ids = statMap.getJSONArray("geography_ids"); 
          JSONObject approval_status = statMap.getJSONObject("approval_status"); 
          String approval_status_text = statMap.getString("approval_status_text"); 
          JSONArray compliance_names = statMap.getJSONArray("compliance_names"); 
          String statutory_nature_name = statMap.getString("statutory_nature_name"); 
          String country_id = statMap.getString("country_id"); 
          String domain_name = statMap.getString("domain_name"); 
          String industry_names = statMap.getString("industry_names"); 
          String is_active = statMap.getString("is_active"); 
          String statutory_nature_id = statMap.getString("statutory_nature_id"); 
          JSONArray statutory_ids = statMap.getJSONArray("statutory_ids"); 
          String country_name = statMap.getString("country_name"); 
          JSONArray industry_ids = statMap.getJSONArray("industry_ids"); 
          JSONArray geography_mappings = statMap.getJSONArray("geography_mappings"); 
          JSONArray compliances = statMap.getJSONArray("compliances"); 
          String compliance_id = statMap.getString("compliance_id"); 
          JSONArray inner_statutory_mappings = statMap.getJSONArray("statutory_mappings"); 
          String domain_id = statMap.getString("domain_id"); 

          String logs = geography_ids + ""+ approval_status + " "+approval_status_text + " "+ compliance_names + " "+ statutory_nature_name + " "+country_id + " "+domain_name + " "+ industry_names + " "+is_active + " "+statutory_ids + " "+statutory_nature_id + " "+ country_name + " "+industry_ids + " "+ geography_mappings + " "+compliances + " "+compliance_id + " "+inner_statutory_mappings + " "+domain_id; 

          Toast.makeText(getActivity(),geography_ids.toString(),Toast.LENGTH_SHORT).show(); 
         } 
        } catch (Exception e) { 
         e.printStackTrace(); 
        } 
       } 

問題はイムができないということです、それを解析しようとしている

イムそれを解析することができます。 geography_idsは印刷されますが、承認ステータスやその他の値は印刷されません。どうしてこんなことに？私は何かの論理を欠いていますか？

Answer 1

問題1あなたのJSONは、この形式は

：あなたはこのアレイの上itterateしようとするので、あなたが得る

[ 
    "GetStatutoryMappingsSuccess", 
    {...} 
] 

を1 Exeption：1番目の要素ではない org.json.JSONException: JSONArray[0] is not a JSONObject.ので、 JsonObjectではなくStringです。あなたがより良いだけではなく、ループ

---

問題2

のための JSONObject value = new JSONArray(json).getJSONObject(1);を使用したい理由は、

インサイド2番目のオブジェクトは、あなたが

{ 
    "statutory_mappings": { 
     "5": { 
      "approval_status": 0, 
      ... 
     } 
    } 
} 

を持っており、あなたの解析コードは動作するはずです"approval_status"はの整数なので、

の代わりに

JSONObject approval_status = statMap.getJSONObject("approval_status"); 

は次のようになります。

int approval_status = statMap.getInt("approval_status"); 

// Same problem for: 

int country_id = statMap.getInt("country_id"); 
boolean is_active = statMap.getBoolean("is_active"); 
int statutory_nature_id = statMap.getInt("statutory_nature_id"); 
int domain_id = statMap.getInt("domain_id"); 

---

問題3

はcompliance_idに問題があるとJSONがこの

"compliances": [ 
    { 
     // ... some fields here 
     "compliance_id": 13 
    }, 
    { 
     // ... some fields here 
     "compliance_id": 14 
    }, 
    ... 
] 

のように見えるので、印刷にも意味がありませんあなたのログ文字列にcompliancesとあなたが本当に配列内のAACH要素のcompliance_idを取得したいあなたは、この

JSONArray compliancesArr = statMap.getJSONArray("compliances"); 
for(int i = 0; i < compliancesArr.length();i++){ 
    JSONObject compliancesObj = compliancesArr.getJSONObject(i); 
    int compliance_id = compliancesObj.getInt("compliance_id"); 
} 

---

PSのようにそれらの上にitterateする必要があります。 GsonまたはJacksonは、解析コードをもっと簡単にします。
