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

a little correction: result.length() length - is a method name in this case

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?
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...
Terminal was not parsed to array it was added to an array. What are you trying to achieve?
sorry...if i ve done it in object, can i get the index of each object in for loop?
