使用GSON JSON包围Android

概述尝试使用下面的2行使用GSON库读取和存储json信封时,应用程序崩溃(请参阅错误日志).解析有什么问题.TypelistType=newTypeToken<ArrayList<MRechercheResult>>(){}.getType();List<MRechercheResult>search_results=newGson().fromJson(envelop,listType);错

尝试使用下面的2行使用GSON库读取和存储Json信封时,应用程序崩溃(请参阅错误日志).解析有什么问题.

Type ListType = new Typetoken<ArrayList<MRechercheResult>>() {}.getType();        List<MRechercheResult>search_results  = new Gson().fromJson(envelop, ListType);

该模型

public class MRechercheResult {    public String ID_profil;    public String ID_customer;    public String profil;    public String profil_photo;    public String email;    public String agenda;    public List<Activite> activite;}public class Activite {    public String day;    public String from;    public String to;}

您可以在此处找到Json信封：

解决方法:

希望对您有所帮助..使用gson时,请务必注意变量名和类型：)

public class MRechercheResult {        public String ID_profil;        public String ID_customer;        public String profil;        public String profil_photo;        public String email;        public Agenda[] agenda;        public Activite[] activite;    }    public class Activite {        public String day;        public String from;        public String to;    }        public class Agenda {        String day;        String from;        String to;    }}
