Read data from JSON Array android

Question

When send email parameters to server and the response is shown as a string below.

[
{
    "nid": "478",
    "field_mc_bacheliers_value": "0",
    "field_mc_defi_collectif_value": "1"
},
{
    "nid": "480",
    "field_mc_bacheliers_value": "0",
    "field_mc_defi_collectif_value": "1"    
}
]

I want to read this response String format into jsonobject. I it is the first time i work with json.

Use JsonArray class. which Parses the json and Create array of JSON Object — Brijesh Thakur, Jun 20 '13 at 09:22
Use [new JSONObject(string)](http://developer.android.com/reference/org/json/JSONObject.html#JSONObject%28java.lang.String%29)... — devconsole, Jun 20 '13 at 09:24
@blackbelt you are right, it is [new JSONArray(string)](http://developer.android.com/reference/org/json/JSONArray.html#JSONArray%28java.lang.String%29) — devconsole, Jun 20 '13 at 09:27

Considering the below extra curly brace removed }

[
{
    "nid": "478",
    "field_mc_bacheliers_value": "0",
    "field_mc_defi_collectif_value": "1"
},
{
    "nid": "480",
    "field_mc_bacheliers_value": "0",
    "field_mc_defi_collectif_value": "1"
}
]

To parse

  JSONArray myListsAll= new JSONArray(myjsonstring);
  for(int i=0;i<myListsAll.length();i++){
  JSONObject jsonobject= (JSONObject) myListsAll.get(i);
  String id=jsonobject.optString("nid");
  String value1=jsonobject.optString("field_mc_bacheliers_value");
  String value2=jsonobject.optString("field_mc_defi_collectif_value");  
  System.out.println("nid="+id);
  System.out.println("value1="+value1);
  System.out.println("value2="+value2); 
  }

Output

nid=478
value1=0
value2=1
nid=480
value1=0
value2=1

Remove this extra curly braces '}'

You can refer below code For the json

[ 
{
  "name" : "Test",
  "id" : 512
}, {
  "name" : "Test2",
  "id" : 573
}, {
  "name" : "Test3",
  "id" : 585
}
]

Parse Like this

ArrayList<String> arrProducts = new ArrayList<String>();

try {
    JSONArray valarray = new JSONArray(jsonstring);
    for (int i = 0; i < valarray.length(); i++) {

        String str = valarray.getJSONObject(i).getString("name");
        arrProducts.add(str);
    }
} catch (JSONException e) {
    Log.e("JSON", "There was an error parsing the JSON", e);
}

Try this

jString=[{"nid":"478","field_mc_bacheliers_value":"0","field_mc_defi_collectif_value":"1"},{"nid":"480","field_mc_bacheliers_value":"0","field_mc_defi_collectif_value":"1"}}]
    jObject = new JSONObject(jString);
   String id = jObject .getString("id");

Hope it helps

It is not valid JSON, you have an extra } at the end.

[
  {
    "nid": "478",
    "field_mc_bacheliers_value": "0",
    "field_mc_defi_collectif_value": "1"
  },
  {
    "nid": "480",
    "field_mc_bacheliers_value": "0",
    "field_mc_defi_collectif_value": "1"
  }
} <-- this is invalid
]
