Jor*_*ens 4 android json dictionary object gson
嘻嘻
我很好奇是否有可能将Map转换为JSON,而使用GSON则反之亦然?我放入的对象已经通过GSON从JSON转换为Object.
我正在使用的对象如下所示:
public class Locations{
private List<Location> location;
<-- Getter / Setter -->
public class Location{
<-- Fields and Getters/Setters -->
}
}

假设你使用的是java.util.Map:
Map<Integer, Object> map = new HashMap<>();
map.put(1, "object");
// Map to JSON
Gson gson = new Gson(); // com.google.gson.Gson
String jsonFromMap = gson.toJson(map);
System.out.println(jsonFromMap); // {"1": "object"}
// JSON to Map
Type type = new TypeToken<Map<String, String>>(){}.getType();
Map<String, String> map = gson.fromJson(json, type);
for (String key : map.keySet()) {
System.out.println("map.get = " + map.get(key));
}
