gson

问题 I'm getting responses from my server that look like: { "timestamp" : 1, "some other data": "blah", "result" : { ... } } for a variety of calls. What I want to do client side is: class ServerResponse<T> { long timestamp; T result; } and then deserialize that with GSON or Jackson. I've been unable to do so thanks to type erasure. I've cheated that using subclasses like this: class SpecificResponse extends ServerRequest<SpecificType> {} but that requires a bunch of useless classes to lie around.

问题 I'm new here and I don't very well speak English, but I do my best to explain me. I have some problems with the Post request.

问题 I have a method that gets the strongest Wifi acces points signal, which avialabe is and returns SSID string, all these SSID strings are stored in the raw folder in JSON file: How can I access the file in the raw folder and parse it with Gson to get for example the route_number 6 if the SSID "FR WLAN" is? ssid_number JSON file: { "data": [ { "ssid": "KD Privat", "route_number": 1 }, { "ssid": "KD WLAN Hotspot", "route_number": 4 }, { "ssid": "FR WLAN", "route_number": 6 } ] } WifiJSON class:

问题 I started using the Google Places api by calling the following url https://maps.googleapis.com/maps/api/place/textsearch/json?query=restaurants+in+Sydney&sensor=true&key=AddYourOwnKeyHere I found a post here on stackoverflow that showed the the basic structure of classes I need to to parse the json with gson. Here is what I have so far. public class GoogleMapper { @SerializedName("debug_info") private List<String> debug_info; @SerializedName("html_attributions") private List<String> html

问题 I have the following json: [ { "type": 1, "Steps": { "steps": steps } }, { "type": 2, "HeartRate": { "heartrates": heartRates } } ] The field steps is just an int an heartRates is an array of int's. I want to parse this using gson to two classes. I found a similar question on stackoverflow: How parse json array with multiple objects by gson? and tried it but it didn't work. This is my code: public class DataModels extends ArrayList<DataModels.Container> { public class Container { public int

问题 According to the json specs, escaping " / " is optional. Gson does not do it by default, but I am dealing with a webservice which is expecting escaped " / ". So what I want to send is " somestring\\/someotherstring ". Any ideas on how to achieve this? To make things clearer: if I try to deserialize " \\/ " with Gson, it will send " \\\\/ ", which is not what I want! 回答1: Answer: The Custom Serializer You can write your own Custom Serializer - I have created one which follows the rule that you

问题 I'm trying to use GSON to deserialize some Json to a nice, tidy object. Now, I have managed to get the Json to correctly map to some of the more obvious variables. However, while trying to map some of the Json I came across this: { "this_number": 1, "that_number": 12, "some_string": "String!", "list_of_objects": { "342356676784653234535345": { "random_double": "0.1235667456456", "magic": "29", "health": 1, "price": 7, "point": { "x": 2, "y": 70 } }, "2345263767467354": { "random_double": "0

问题 I'm getting the following error com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $ There are some other solutions out there, but none have worked for me. Most seem to be talking about having to make Call<WordOfTheDay> into Call<List<WordOfTheDay>> , but since the json is not an array that does not help. I believe it's the JSON, but am not sure. JSON {"id":520687,"word":"imbricated","contentProvider":{"name":
