I am trying to get the values from a JSON response. I got everything to work, except extracting an array from the following string:
{"o":"1.18988","h":"1.18993","l":"1.18963","c":"1.18993"}
I know GSON is trying to parse it because I get this error:
Exception in thread "main" java.lang.IllegalStateException: Not a JSON Array: {"o":"1.18988","h":"1.18993","l":"1.18963","c":"1.18993"}
I am using the following code to attempt to parse it:
final JsonElement midElement = obj.get("mid");
final JsonArray midArray = midElement.getAsJsonArray();
for(Object rate : midArray){
final JsonObject rateObj = (JsonObject)rate;
final JsonElement openElement = rateObj.get("o");
open = openElement.getAsFloat();
final JsonElement highElement = rateObj.get("h");
high = highElement.getAsFloat();
final JsonElement lowElement = rateObj.get("l");
low = lowElement.getAsFloat();
final JsonElement closeElement = rateObj.get("c");
close = closeElement.getAsFloat();
}
First of all it doesn't look like a valid JSON array. It should look like this
[{"o":"1.18988","h":"1.18993","l":"1.18963","c":"1.18993"}]
Try this following code to parse it in JSON format.
JSONObject jsonObject = new JSONObject(jsonString);
JSONArray jsonArray = jsonObject.getJSONArray("mid");
for (int i = 0; i < jsonArray.length(); i++) {
jsonArray.getJSONObject(i).getString("o");
}
Then convert it your preferred data form.
