Please help me create jSonArray without keys. It should looks like:
"main" : ["one", "two", "three"]
I have tried it with empty key value:
private String generate(String value) {
Gson gson = new Gson();
JsonArray jsonArray = new JsonArray();
JsonObject jsonObject = new JsonObject();
jsonObject.addProperty("", value);
jsonArray.add(jsonObject);
return gson.toJson(jsonArray);
}
Result looks bad..
"main": "[
{\"\":\
"myString value\"}
]"
JsonObject obj = new JsonObject();
JsonArray array = new JsonArray();
array.add(new JsonPrimitive("one"));
array.add(new JsonPrimitive("two"));
array.add(new JsonPrimitive("three"));
obj.add("main", array);
You can do something like:
Gson gson = new Gson();
JsonArray array = new JsonArray();
array.add(new JsonPrimitive("one"));
array.add(new JsonPrimitive("two"));
array.add(new JsonPrimitive("three"));
JsonObject jsonObject = new JsonObject();
jsonObject.add("main", array);;
System.out.println(gson.toJson(jsonObject));
which outputs:
{"main":["one","two","three"]}
[{"iGuestId":["88","89"]},{"iUserId":"2"}] please give solution for thisWhat you are trying to do is just to fill an array with primitive variables, to achieve that you have to change your code like this:
private String generate(String value) {
Gson gson = new Gson();
JsonArray jsonArray = new JsonArray();
jsonArray.add(new JsonPrimitive(value));
return gson.toJson(jsonArray);
}
Sample Code
JSONObject obj = new JSONObject();
JSONArray list = new JSONArray();
list.add("msg 1");
list.add("msg 2");
list.add("msg 3");
obj.put("", list);
You can use this to put an array without key.
