"2": [{ "m_id": "149", "m_flag": "1", "m_type": "2", "m_name": "\u30da\u30fc

问题 I have the json: {"test": [{"param1": "param"}], "test2": "test", "test3": "test2"} how can I get fromGson to parse the arrays in a json correctly so that it populates the arrays into an array of a particular object type. So test should map to TestObject[] test; test2 -> String test2; test3 -> String test3; I tried gson.fromJson(response, TestData.class); that gave me an error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line

问题 I have the following json string: [ { "question" : { "questionId" : 1109, "courseId" : 419 }, "tags" : ["PPAP", "testtest"], "choices" : [{ "choiceId" : 0, "questionId" : 0 }, { "choiceId" : 0, "questionId" : 0 } ] } ] How do I make question, tags, and choices into separate objects using GSON? Currently I only use fromJson and can only convert a JSON string if it only contains 1 type of object. 回答1: You can have following classes class Question{ questionId; //specify data type courseId; }

问题 What is the best way from the given JSON to generate List of SimpleTestClass type where there's a new SimpleTestClass object for the values in the recipients array in the JSON with code set as well. public class SimpleTestClass{ String code; String recipient; } JSON payload: { "code": 123, "recipients": [ "888888", "222222" ] } 回答1: If JSON structure does not fit to POJO model you need to write custom deserialiser or create a new POJO model which fits JSON and after deserialisation process

问题 I'm calling a web service that returns JSON. Within that JSON I have a property that holds a URL. But the colon (:) within that URL is making Gson throw a gson.stream.MalformedJsonException error. I know these keys and values should be wrapped JSON returned by web service: { ID=15; Code=ZPFgNr; UserName=https://www.google.com/accounts/o8/id?id=xxxxxx; //<--problem FirstName=Joe } My Java: resultData=((SoapObject) result).getProperty(0).toString(); User response = gson.fromJson(resultData,

问题 I am starting to look at google's Gson. The following code errors as it is entered in that the Gson in the last line is not recognised. The imports are ok so what am I missing? import com.google.gson.*; import com.google.gson.stream.*; public class BuildJsonObject { Gson myGson = new Gson(); } 回答1: Did you add the GSON Jar to your build path? Right Click (Project) -> Build Path -> Configure Build Path... -> Go To 'Libraries' Tab -> Click 'Add External JARs...' then select the GSON jar file?

问题 I want to use GSON to decode an array of maps in which the keys are not Strings. I know that the JSON type does not allow for objects to be used as keys, so I was hoping it is possible to have GSON work recursively to decode Strings. Java public class Reader { static class Key { int a; int b; } static class Data { HashMap<Key, Integer> map; } public static void read() { Gson gson = new Gson(); String x = "[{\"map\": { \"{\\\"a\\\": 0, \\\"b\\\": 0}\": 1 }}]"; Data[] y = gson.fromJson(x, Data[

问题 I’m using Gson and Universal Image Loader. I used this project like a template (you need change version to run it, it shows in tutorial): tutorial: https://www.youtube.com/watch?v=X2mY3zfAMfM link to this project: https://github.com/hishamMuneer/JsonParsingDemo I aded images in nested part of JSON and created listView in second activity to display it. { "movies": [ { "movie": "Avengers", "cast": [ { "name": "Robert Downey Jr.", "image": "www.mywebsite.com/img2.png" }, { "name": "Chris Evans",

问题 I have a top level scala class something like below: FinalOutput.scala: class FinalOutput extends Serializable { @BeanProperty var userId: String = _ @BeanProperty var tenantId: String = _ @BeanProperty @SerializedName("type") var dataType: String = _ @BeanProperty var data: FinalData = _ @BeanProperty var userCreatedDate: String = _ } FinalData.scala : class FinalData extends Serializable { @BeanProperty var list1: ArrayBuffer[DataType1] = _ @BeanProperty var list2: ArrayBuffer[DataType2] =

问题 Ok I have a json coming in that looks like this: {count:xxx, important:[{...}]} All I care about is the important object. Is there anything I can do with a custom deserializer or anything where I can just have GSON deserialize that important json object? Also the way I want the deserialized object to look is like this: List<Important> = Gson.fromJson(arg0, new TypeToken<ArrayList<Important>>(){}.getType() ); 回答1: Yes, you can use the JsonParser class from the Gson library to read it as a
