Parse JSON Antwort mit GSON in reterofit

Question

Ich habe die Nachrüstung SDK für die Herstellung von API-Anruf verwendet. Ich habe GSON SDK zum Parsen der Antwort. Ich habe etwas schwierig, die JSON-Antwort zu analysieren. Ich habe die JSON-Antwort geschrieben, die unten analysiert werden soll. Ich muss die Adresszeile Arraylist erhalten.

Ich bekomme Null Daten von der Liste.

{ 
    "QA": { 
     "CreditsUsed": 1, 
     "State": "Results" 
    }, 
    "SearchResult": { 
     "VerifyLevel": "Verified", 
     "Address": { 
      "AddressLine": [{ 
       "LineContent": "None", 
       "Label": {}, 
       "Line": "2500Kearney St" 
      }, { 
       "LineContent": "None", 
       "Label": {}, 
       "Line": {} 
      }, { 
       "LineContent": "None", 
       "Label": {}, 
       "Line": {} 
      }, { 
       "Label": "City name", 
       "Line": "Springfield" 
      }, { 
       "Label": "State code", 
       "Line": "MO" 
      }, { 
       "Label": {}, 
       "Line": "65803-5048" 
      }, { 
       "Label": "Country", 
       "Line": "UNITED STATES OF AMERICA" 
      }], 
      "DPVStatus": "DPVNotConfigured" 
     }, 
     "VerificationFlags": { 
      "StateProvinceChanged": true, 
      "PostCodeCorrected": true 
     } 
    } 
}

Answer 1

ich die json extra behoben haben "" wie unten gezeigt .

"StateTransition":"SearchResults", 

Nach dem Parsen von rektifiziertem json in http://www.jsoneditoronline.org/. Mir ist aufgefallen, dass du in deinem jsonObject noch 2 jsonObject mit den Schlüsseln "CAB" und "Result" hast. In Ihrem zweiten jsonObject haben Sie ein anderes jsonObject mit dem Schlüssel "Address", innerhalb dessen Sie das Array "AddressLine" haben.

SO Bitte korrigieren Sie die komplette pojo DineshValues. Wenn Sie weitere Hilfe benötigen, dann lassen Sie mich wissen, ich komplett POJO hinzufügen wird

UPDATE
Lösung 1-
Wie in Kommentar erwähnt, dass Sie jsonschema2pojo pojo zu erzeugen, verwendet, können Sie diese Klassen halten die könnte einfach den Code und verwenden Sie die folgende Zeile Adresse zu extrahieren

List<AddressLine> addressLine = arg0.getResult().getAddress().getAddressLine() 

Jetzt Adresszeile durchlaufen und die Daten extrahieren, die Sie benötigen.

Hinweis - 1) Stellen Sie sicher, dass arg0 vom Typ class für root JsonObject ist.
2) Ein weiterer Punkt ist wie erwähnt von cricket_007 - Jedes Label und Zeile Attribut sind keine Zeichenfolgen, sie sind Objekte, wie von {}.

Lösung 2-
Sie nur die Address Klasse aus der generierten Klassendatei in Ihrem Projekt behalten und verwenden Sie die folgenden Zeilen Adresse zu extrahieren.

RetrofitRest.getClient().getLogin("1111111" ,obj,new Callback<DineshValues >() { 

    @Override 
     public void success(String arg0, Response arg1) { 
      // TODO Auto-generated method stub 
      JsonObject rootJsonObject = new JsonObject(arg0); 
      JsonObject searchResultJsonObject = rootJsonObject.getJsonObject("SearchResult"); 
      JsonObject addressJsonObject = searchResultJsonObject.getJsonObject("Address") 

      Type listType = new TypeToken<List<AddressLine>>(){}.getType(); 
      List<AddressLine> addressLineList = gson.fromJson(addressJsonObject, listType); 
      //Now iterate the addressLineList to get the address 
      Log.e("size",addressLineList.getSize+""); 

     } 
} 

Answer 2

Bitte versuchen Sie es mit unter POJO,

Adresse

public class Address { 

    @SerializedName("AddressLine") 
    private List<AddressLine> addressLine = new ArrayList<AddressLine>(); 
    @SerializedName("DPVStatus") 
    private String dPVStatus; 

    /** 
    * 
    * @return 
    *  The addressLine 
    */ 
    public List<AddressLine> getAddressLine() { 
     return addressLine; 
    } 

    /** 
    * 
    * @param addressLine 
    *  The AddressLine 
    */ 
    public void setAddressLine(List<AddressLine> addressLine) { 
     this.addressLine = addressLine; 
    } 

    /** 
    * 
    * @return 
    *  The dPVStatus 
    */ 
    public String getDPVStatus() { 
     return dPVStatus; 
    } 

    /** 
    * 
    * @param dPVStatus 
    *  The DPVStatus 
    */ 
    public void setDPVStatus(String dPVStatus) { 
     this.dPVStatus = dPVStatus; 
    } 

}

    /**

    *  The lineContent 
    */ 
    public String getLineContent() { 
     return lineContent; 
    } 

    /** 
    * 
    * @param lineContent 
    *  The LineContent 
    */ 
    public void setLineContent(String lineContent) { 
     this.lineContent = lineContent; 
    } 

    /** 
    * 
    * @return 
    *  The label 
    */ 
    public String getLabel() { 
     return label; 
    } 

    /**

    *  The Label 
    */ 
    public void setLabel(String label) { 
     this.label = label;
