Question

I have the following array response from a server to an android app.

[
{"1":
[{"name":"IEEE Meeting"},{"date":"2012-04-24 10:30:00"},{"Room":"ZACH102"},{"descr":"Final Meeting"},{"D":0.0057}]},
{"2":
[{"name":"Senior Design Demo"},{"date":"2012-04-24 16:30:00"},{"Room":"ZACH111A"},{"descr":"Demo"},{"D":0.019}]}
]

I perform a conversion to a JSONArray after receiving the response.

arr = new JSONArray(sb.toString());

How would I go about extracting the individual elements of name, date, room and so on?

Answer 1

So basically, its of this order
Array of objects 1, 2
– Each object 1, 2 has an array of different objects name, date, etc.

1. Convert the whole data in to a string.
2. Create a new JSONArray(string).
3. Loop over the array. (you’ll get the count using length()).
4. Get the first object by using getJSONObject().
5. Get the array in the first object using getJSONArray.
6. Now using length() again you’ll get the number of JSONObjects in it.
7. Loop over the num of objects and call get JSONObject() first followed by getString() or getDouble().
8. Repeat over the list of other objects and repeat step 4 – 7.
