I need some help here. I am still new in android developer.

Here is example of the data

strAPI_TERMINAL= "{ 'terminal': { 'id': 2, 'fmt_id': 'fmt0002', 'terminal_type': 'multiple' }}"

I need to parse this object data to JSONArray

Here what i ve done...

JSONObject jsonObject = new JSONObject(strAPI_TERMINAL);
JSONArray terminal_array = new JSONArray();
JSONArray t_array = terminal_array.put(jsonObject);

When I Log out the data...yes it has been parse to array just like this

t_array[{"terminal":{"fmt_id":"fmt0002","id":2,"terminal_type":"multiple"}]

But When I wanna use it to get the "terminal" data using this...

JSONArray TERMINAL_JSON=new JSONArray(t_array.getJSONObject(i).getString("terminal").toString());

It says:

Error:Value {"id":2,"fmt_id":"fmt0002","terminal_type":"multiple"}

Anyone please help me???

thanks for any help...

Try out parse JSON as below:

JSONObject obj1 = new JSONObject(strAPI_TERMINAL);
 try {
  JSONArray result = obj1.getJSONArray("terminal");
for(int i=0;i<=result.length();i++)
 {
    String Id=result.getString("fmt_id");
      String terminalType=result.getString("terminal_type");
 }
 } catch (JSONException e) {
     e.printStackTrace();
}

Hope this will help you.

Thanks

As Josnidhin said, 'terminal' is a JSON Object. If you want it to be an array, you need to make it so in the first place (notice the array brackets):

strAPI_TERMINAL= "{ 'terminal': [{ 'id': 2, 'fmt_id': 'fmt0002', 'terminal_type': 'multiple' }]}"

Are you really just trying to iterate through the keys in the terminal object? If so, maybe you would want to check out this post: How to iterate over a JSONObject?

According to your code't_array' is an array of JSONObject. To access each item in 't_array' you will need to get each item as JSONObject and then access the values of that JSONObject.

The value of 'terminal' is a json object you cant convert it to json array just like that.

To access the value of 'terminal' do something like the following

t_array.getJSONObject(i).getJSONObject("terminal");

The above code will return the following as JSONObject

{ 'id': 2, 'fmt_id': 'fmt0002', 'terminal_type': 'multiple' }

  • Yes...but when i doing for loop it repeated..because i cannot take the index of the data...not like JSONArray..i can use index to get the exact data...any idea? – Nik Faris Aug 29 '13 at 03:38
  • And also...the terminal is already parse to Array if you see the log t_array[{"terminal":{"fmt_id":"fmt0002","id":2,"terminal_type":"multiple"}]...but i am not sure it is really converted or not... – Nik Faris Aug 29 '13 at 03:40
  • Terminal was not parsed to array it was added to an array. What are you trying to achieve? – Josnidhin Aug 29 '13 at 03:52
  • sorry...if i ve done it in object, can i get the index of each object in for loop? – Nik Faris Aug 29 '13 at 03:55
