This is an example for how to handle dynamic key for response. Here A and B are dynamic keys it can be anything
Response
{
"response": [
{
"A": [
{
"name": "Tango"
},
{
"name": "Ping"
}
],
"B": [
{
"name": "Jon"
},
{
"name": "Mark"
}
]
}
]
}Java code
// ResponseData is raw string of response
JSONObject responseDataObj = new JSONObject(responseData);
JSONArray responseArray = responseDataObj.getJSONArray("response");
for (int i = 0; i < responseArray.length(); i++) {
// Nodes ArrayList<ArrayList<String>> declared globally
nodes = new ArrayList<ArrayList<String>>();
JSONObject obj = responseArray.getJSONObject(i);
Iterator keys = obj.keys();
while(keys.hasNext()) {
// Loop to get the dynamic key
String currentDynamicKey = (String)keys.next();
// Get the value of the dynamic key
JSONArray currentDynamicValue = obj.getJSONArray(currentDynamicKey);
int jsonArraySize = currentDynamicValue.length();
if(jsonArraySize > 0) {
for (int ii = 0; ii < jsonArraySize; ii++) {
// NameList ArrayList<String> declared globally
nameList = new ArrayList<String>();
if(ii == 0) {
JSONObject nameObj = currentDynamicValue.getJSONObject(ii);
String name = nameObj.getString("name");
System.out.print("Name = " + name);
// Store name in an array list
nameList.add(name);
}
}
}
nodes.add(nameList);
}
