我需要轉換以下類:
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 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;
}
是以Class ExerciseSession有一組LatLon對象.現在我需要将ExerciseSession類從java轉換為Json格式并将其發送到我的伺服器.
我在Android作業系統上這樣做,如果這很重要.
我目前的解決方案是:
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);
}
我不确定這是否有效..我是Json的新手,需要幫助.
在此先感謝您的幫助!
