Senden von JSON-Objekten innerhalb des Arrays an Server

Question

Ich bin sehr neu und ich versuche, dynamische Objekte in einem Array durch volley zu senden. Sie können dies auf http://www.jsoneditoronline.org/ überprüfen. Ich fummelte am Codieren, so würde jede Hilfe sehr geschätzt werden. Unten ist ein Ausschnitt aus meinem Code, wo Objekte dynamisch sein würde, wo ich von Spinner Auswahl würde und sie an den Server

[ 
    { 
     "longDescription":"Carrot Cheese Paratha is perfect to attract kids as it is colorful and yummy...", 
     "productName":"CARROT CHEESE PARATHA", 
     "name":"Delicious Kids Meal", 
     "productId":"Monday", 
     "catalogName":"KIDS TIFFIN MENU", 
     "categoryName":"Monday", 
     "subCategoryName":"Long Break", 
     "kidId":47 
    }, 
    { 
     "longDescription":"Freshly cooked Desi Ghee Paratha along with Paneer butter masala", 
     "productName":"Paratha plus paneer butter masala", 
     "name":"Delicious Kids Meal", 
     "productId":"Monday", 
     "catalogName":"KIDS TIFFIN MENU", 
     "categoryName":"Monday", 
     "subCategoryName":"Short Break", 
     "kidId":47 
    }, 
    { 
     "longDescription":"Basmati Rice along with freshly cooked Matar Paneer (cottage Cheese)", 
     "productName":"Matar paneer and Basmati Rice", 
     "name":"Delicious Kids Meal", 
     "productId":"Wednesday", 
     "catalogName":"KIDS TIFFIN MENU", 
     "categoryName":"Wednesday", 
     "subCategoryName":"Short Break", 
     "kidId":47 
    } 
] 

Answer 1

Senden Sie können diese JsonArrayRequest

RequestQueue requestQueue = Volley.newRequestQueue(this); 
    final String jsonString = "your json here"; 
    try { 
     JSONArray jsonArray = new JSONArray(jsonString); 
     JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.POST, url, jsonArray, new Response.Listener<JSONArray>() { 
      @Override 
      public void onResponse(JSONArray response) { 
       // 
      } 
     }, new Response.ErrorListener() { 
      @Override 
      public void onErrorResponse(VolleyError error) { 
       // 
      } 
     }); 
     requestQueue.add(jsonArrayRequest); 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 

Answer 2

Ihre Modell-Klasse tun.

public class test { 

/** 
* longDescription : Carrot Cheese Paratha is perfect to attract kids as it is colorful and yummy... 
* productName : CARROT CHEESE PARATHA 
* name : Delicious Kids Meal 
* productId : Monday 
* catalogName : KIDS TIFFIN MENU 
* categoryName : Monday 
* subCategoryName : Long Break 
* kidId : 47 
*/ 

private String longDescription; 
private String productName; 
private String name; 
private String productId; 
private String catalogName; 
private String categoryName; 
private String subCategoryName; 
private int kidId; 

public String getLongDescription() { 
    return longDescription; 
} 

public void setLongDescription(String longDescription) { 
    this.longDescription = longDescription; 
} 

public String getProductName() { 
    return productName; 
} 

public void setProductName(String productName) { 
    this.productName = productName; 
} 

public String getName() { 
    return name; 
} 

public void setName(String name) { 
    this.name = name; 
} 

public String getProductId() { 
    return productId; 
} 

public void setProductId(String productId) { 
    this.productId = productId; 
} 

public String getCatalogName() { 
    return catalogName; 
} 

public void setCatalogName(String catalogName) { 
    this.catalogName = catalogName; 
} 

public String getCategoryName() { 
    return categoryName; 
} 

public void setCategoryName(String categoryName) { 
    this.categoryName = categoryName; 
} 

public String getSubCategoryName() { 
    return subCategoryName; 
} 

public void setSubCategoryName(String subCategoryName) { 
    this.subCategoryName = subCategoryName; 
} 

public int getKidId() { 
    return kidId; 
} 

public void setKidId(int kidId) { 
    this.kidId = kidId; 
} 

}

VolleyJsonPost Methode von VolleyConnection Klasse, die ich schrieb:

public static void jsonPost(Context context, String url, JSONObject jsonObject, Response.Listener<JSONObject> responceListener, Response.ErrorListener errorListener) 
{ 
    JsonObjectRequest jsonRequest = new JsonObjectRequest(Request.Method.POST,url,jsonObject,responceListener,errorListener); 

    Volley.newRequestQueue(context).add(jsonRequest); 
} 

und Sie auf diese Weise:

VolleyConnection.jsonPost(context, rootUrl, jsonObject, new Response.Listener<JSONObject>() { 
     @Override 
     public void onResponse(JSONObject response) { 


      try { 
       // do stuff 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 
     } 
    }, new Response.ErrorListener() { 
     @Override 
     public void onErrorResponse(VolleyError error) { 
      error.printStackTrace(); 
     } 
    }); 

}
