Android进阶篇Parcelable包裹类

Bundle传递数据的时候，我们会发现传递Serializable集合会抛出IO异常。

这个时候我们就必须使用Parcelable包裹类。

Message.java:

public class Message implements Parcelable{
    @DatabaseField(generatedId = true,unique=true)
    int id;
    @DatabaseField
    private String Mid;//消息ID
    private MessageContent Content;//消息内容
    @DatabaseField
    private String Functionid;//消息类型Id
    @DatabaseField
    private String Sendtime;//发送时间
    @DatabaseField
    private String Tid;//发送者ID”
    @DatabaseField
    private String Tname;//发送者姓名
    
    public String getMid() {
        return Mid;
    }
    public void setMid(String mid) {
        Mid = mid;
    }
    public MessageContent getContent() {
        return Content;
    }
    public void setContent(MessageContent content) {
        Content = content;
    }
    public String getMtypeid() {
        return Functionid;
    }
    public void setMtypeid(String mtypeid) {
        Functionid = mtypeid;
    }
    public String getSendtime() {
        return Sendtime;
    }
    public void setSendtime(String sendtime) {
        Sendtime = sendtime;
    }
    public String getTid() {
        return Tid;
    }
    public void setTid(String tid) {
        Tid = tid;
    }
    public String getTname() {
        return Tname;
    }
    public void setTname(String tname) {
        Tname = tname;
    }
    
    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        // TODO Auto-generated method stub
        dest.writeString(Mid);
        dest.writeSerializable(Content);
        dest.writeString(Functionid);
        dest.writeString(Sendtime);
        dest.writeString(Tid);
        dest.writeString(Tname);
    }
    
    public static final Parcelable.Creator<Message> CREATOR = new Parcelable.Creator<Message>() {

        @Override
        public Message createFromParcel(Parcel source) {
            // TODO Auto-generated method stub
            Message msg = new Message();   
            msg.Mid = source.readString();
            msg.Content = (MessageContent) source.readSerializable();
            msg.Functionid = source.readString();
            msg.Sendtime = source.readString();
            msg.Tid = source.readString();
            msg.Tname = source.readString();
            return msg;   
        }

        @Override
        public Message[] newArray(int size) {
            // TODO Auto-generated method stub
            return null;
        }
    };  
}

Messages.java:

public class Messages implements Parcelable{
    private static final long serialVersionUID = 1L;
    
    private String Result;//错误码  0为返回成功 非0为返回失败
    private String Message;//错误描述
    private List<Message> Messages;
    
    public List<Message> getMessages() {
        return Messages;
    }

    public void setMessages(List<Message> messages) {
        Messages = messages;
    }

    public String getResult() {
        return Result;
    }

    public void setResult(String result) {
        Result = result;
    }

    public String getMessage() {
        return Message;
    }

    public void setMessage(String message) {
        Message = message;
    }

    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        // TODO Auto-generated method stub
        dest.writeString(Result);
        dest.writeString(Message);
        dest.writeList(Messages);
    }
    
    public static final Parcelable.Creator<Messages> CREATOR = new Parcelable.Creator<Messages>() {

        @Override
        public Messages createFromParcel(Parcel source) {
            // TODO Auto-generated method stub
            Messages messages =  new Messages();
            messages.Result = source.readString();
            messages.Message = source.readString();
            messages.Messages =  source.readArrayList(Message.class.getClassLoader());
            return messages;
        }

        @Override
        public Messages[] newArray(int size) {
            // TODO Auto-generated method stub
            return null;
        }

    };
}
