I am using JSONArray under the org.json
Package.
My first JSONArray is like:
[["249404","VPR249404"],["249403","VPR249403"],["249391","M249391"]]
and Second
[["249386","M249386"],["249385","M249385(I)"],["249384","I249384"]]
So I'd like to append new JSONArray to my first JSONArray.
I am working on Java and Android. I have hea开发者_如何学Gord about google-gson library, but I don't know whether it can help me or not but I don't want any other dependency in my Android Application.
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;
}
try this:
private JSONArray concatArray(@NotNull JSONArray jsArr1, @NotNull JSONArray jsArr2) {
List<Object> list = jsArr1.toList();
list.addAll(jsArr2.toList());
return new JSONArray(list);
}
Use ...
jarray1.addAll(jarray2);
