Is it possible to store multiple different JSONObject
s into a single JSONArray
? This is the structure, I want to store in a JSONArray
.
[{"value1":1,"value2":900,"value3":1368349},{"value1":2,"value2":1900,"value3":136856},{"value1":3,"value2":600,"value3":136845}]
Here's the code where I am setting JSONObject
and putting it into a JSONArray
if(somecondition) {
// putting values to json object
jsonObj.put("value1", 1);
jsonObj.put("value2", 900);
jsonObj.put("value3", 1368349);
}
for(int i=0;i<=jsonArray.length();i++){
jsonArray.put(jsonObj);
appObj.setJsonAlarmArray(jsonArray);
// appObj is object of Application Class
editor= sharedPrefs.edit();
editor.putString("key", jsonArray.toString());
System.out.println(jsonArray.toString());
editor.commit();
}
Using this code only the last value, which I am setting in JSON object Override to all objects. Any suggestions to achieve this?
From android API Level 19, when I want to instance JSONArray object I put JSONObject directly as parameter like below:
JSONArray jsonArray=new JSONArray(jsonObject);
JSONArray has constructor to accept object.
Once you have put the values into the JSONObject then put the JSONObject into the JSONArray staright after.
Something like this maybe:
jsonObj.put("value1", 1);
jsonObj.put("value2", 900);
jsonObj.put("value3", 1368349);
jsonArray.put(jsonObj);
Then create new JSONObject, put the other values into it and add it to the JSONArray:
jsonObj.put("value1", 2);
jsonObj.put("value2", 1900);
jsonObj.put("value3", 136856);
jsonArray.put(jsonObj);
