Concatenate JSONArrays
I would try something like this:
private JSONArray concatArray(JSONArray arr1, JSONArray arr2)
throws JSONException {
JSONArray result = new JSONArray();
for (int i = 0; i < arr1.length(); i++) {
result.put(arr1.get(i));
}
for (int i = 0; i < arr2.length(); i++) {
result.put(arr2.get(i));
}
return result;
}
I don't have a compiler right now to test, but you can give it a try and see if it works (or, at least, it gives you an idea of how to do it).
EDIT
This version could concat multiple arrays (concatArray(arr1, arr2, arr3)
):
private JSONArray concatArray(JSONArray... arrs)
throws JSONException {
JSONArray result = new JSONArray();
for (JSONArray arr : arrs) {
for (int i = 0; i < arr.length(); i++) {
result.put(arr.get(i));
}
}
return result;
}
