Mointy :
I have a JsonArray as a string with multiple JsonObjects in it. Since I am not a java developer I am a little bit confused, since it is so complicated to convert JsonObjects into strings and strings into JsonObjects.
I have this JsonArray as a string.
[{
"id":"XXXX-XXXX-XXXX-XXXX-XXXX",
"name":"Name"
},{
"id":"XXXX-XXXX-XXXX-XXXX-XXXX",
"name":"Name"
}]
It changes and I don't know what data it includes.
Goal: I need to convert the json string into JsonArray so I can work with. I tried gson but I only got empty objects.
What I tried:
Gson g = new Gson();
JSONObject jsons[] = g.fromJson(JsonString, JSONObject[].class);
Output:
Log.e ( "JSON", Integer.toString(jsons.length)); ---> 2 (Right!)
Log.e ( "JSON", jsons[0].toString()); ---> { } empty Object
Demetrio :
You have to use JsonArray instead of JsonObject[].
Sample code:
String json = "[{ " +
" \"id\":\"XXXX-XXXX-XXXX-XXXX-XXXX\", " +
" \"name\":\"Name\" " +
"},{ " +
" \"id\":\"XXXX-XXXX-XXXX-XXXX-XXXX\", " +
" \"name\":\"Name\" " +
"}]";
Gson gson = new Gson();
JsonArray array = gson.fromJson(json,JsonArray.class);
System.out.println(array);
Output:
[{"id":"XXXX-XXXX-XXXX-XXXX-XXXX","name":"Name"},{"id":"XXXX-XXXX-XXXX-XXXX-XXXX","name":"Name"}]
If you want to work with a JsonObject[] you could do something like this:
JsonArray array = gson.fromJson(json,JsonArray.class);
JsonObject[] objects = new JsonObject[array.size()];
for(int i=0;i<array.size();i++)
objects[i] = array.get(i).getAsJsonObject();
for(JsonObject x : objects)
System.out.println(x);
Output:
{"id":"XXXX-XXXX-XXXX-XXXX-XXXX","name":"Name"}
{"id":"XXXX-XXXX-XXXX-XXXX-XXXX","name":"Name"}
