Convert normal Java Array or ArrayList to Json Array in android

Question

Is there any way to convert a normal Java array or ArrayList to a Json Array in Android to pass the JSON object to a webservice?

Answer 1

example key = "Name" value = "Xavier" and the value depends on number of array you pass in

 try
      {
      JSONArray jArry=new JSONArray();
      for (int i=0;i<3;i++)
      {
       JSONObject jObjd=new JSONObject();
       jObjd.put("key", value);
       jObjd.put("key", value);
       jArry.put(jObjd);
      }
      Log.e("Test", jArry.toString());
      }
 catch(JSONException ex)
     {

     }

Code

List<String>a = new ArrayList<String>();
a.add("so 1");
a.add("so 2");
a.add("so 3");
JSONArray jray = new JSONArray(a);

System.out.println(jray.toString()); 

output

["so 1","so 2","so 3"]
