I'm new to Java and programming for Android and I've seen a lot of tutorials but I am kinda clueless atm on how to loop through a JSONObject and set it to my class.
Example of JSON data: http://sickbeard.com/api/#history
Class I made:
public Episode(JSONObject obj) {
try {
this.id = Integer.parseInt(obj.getString("episode").toString());
this.tvId = Integer.parseInt(obj.getString("tvdbid").toString());
this.resource = obj.getString("resource").toString();
} catch (NumberFormatException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}
I came as far as this...
ArrayList<Episode> episodeList = new ArrayList<Episode>();
JSONObject data = new JSONObject();
for(int i = 0; i < 2; i++) {
try {
data = response.getJSONObject("data");
episodeList.add(new Episode(data));
} catch (JSONException e) {
e.printStackTrace();
}
}
return null;
// for each entry create new episode :)
} else {
return null;
}

// is = entity.getContent();
ArrayList<String> myList = new ArrayList<String>();
//convert response to string
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
} catch (Exception e) {
Log.e("log_tag", "Error converting result "+e.toString());
}
//parse json data
try{
jArray = new JSONArray(result);
for(int i=0;i<jArray.length();i++){
json_data = jArray.getJSONObject(i);
myList.add(json_data.getString("id"));
Log.i("log_tag","id: " + json_data.getString("id"));
}
}
catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
return myList;
// then u can recieve this myList :
ArrayList<String> get_data_id = postData();
// get_data_id = myList
get_data_id.get(0) - it is first element,
get_data_id.get(1) - it is second element
.... EXAMPLE
json data is : [{"id":"1"},{"id":"2"},{"id":"3"},{"id":"4"},{"id":"5"},{"id":"6"}]
{in loop} myList.add(json_data.getString("id"));
get_data_id.get(0) = 1
get_data_id.get(1) = 2
get_data_id.get(2) = 3
..........
:)
Good Luck

Found it :)
try {
response = new JSONObject(con.query("history", parameters));
JSONArray data = response.getJSONArray("data");
for(int i = 0; i < data.length(); i++) {
try {
episodeList.add(new Episode((JSONObject) data.get(i)));
} catch (JSONException e) {
e.printStackTrace();
}
}
} catch (JSONException e) {
e.printStackTrace();
}
