我需要转换以下类: package comS309.traxz.data;
import java.util.Collection;
import org.json.JSONException;
import org.json.JSONObject;
public class ExerciseSession {
public String DateCreated;
public String TotalTime;
public String CaloriesBurned;
public String AvgSpeed;
public String SessionName;
public String Distance;
public String SessionType;
public String UserId;
public Collection<LatLon> LatLons;
}
LatLon如下: public class LatLon {
public String LatLonId;
public String Latitude;
public String Longitude;
public String ExerciseSessionId;
public String LLAveSpeed;
public String Distance;
}
所以Class ExerciseSession有一组LatLon对象.现在我需要将ExerciseSession类从java转换为Json格式并将其发送到我的服务器. 我在Android操作系统上这样做,如果这很重要. 我目前的解决方案是: JSONObject ExerciseSessionJSOBJ = new JSONObject();
ExerciseSessionJSOBJ.put("DateCreated",this.DateCreated);
ExerciseSessionJSOBJ.put("TotalTime",this.TotalTime);
ExerciseSessionJSOBJ.put("CaloriesBurned",this.CaloriesBurned);
ExerciseSessionJSOBJ.put("AvgSpeed",this.AvgSpeed);
ExerciseSessionJSOBJ.put("SessionName",this.SessionName);
ExerciseSessionJSOBJ.put("Distance",this.Distance);
ExerciseSessionJSOBJ.put("SessionType",this.SessionType);
ExerciseSessionJSOBJ.put("UserId",this.UserId);
//add the collection
for(LatLon l: LatLons)
{
ExerciseSessionJSOBJ.accumulate("LatLons",l);
}
我不确定这是否有效..我是Json的新手,需要帮助. 解决方法使用Google的GSON库非常容易.这是一个使用示例:Gson gson = new Gson(); String jsonRepresentation = gson.toJson(myComplexObject); 并获得对象: Gson gson = new Gson(); MyComplexObject myComplexObject = gson.fromJson(jsonRepresentation,MyComplexObject.class); http://code.google.com/p/google-gson/ (编辑:安卓应用网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
