在新活动中无法检索额外的数据

问题描述

当我在Recycler View内单击CardView时，我已将Parcelable实现为要在活动之间传递的对象。唯一的问题是对象（ResultsHelperClass）在收到意图后总是具有修改后的值。

此刻我完全被困住了，因为我似乎找不到问题。

我作为附加对象传入的对象具有正确的值，但是无论我如何尝试接收它，它的值始终都会更改。

我的ResultsHelperClass

public class ResultsHelperClass implements Parcelable {

    int  localscore,visitorscore,teamId;
    String teamName,locallogoUrl,visitorlogoUrl,local,date;

      //Constructor
public ResultsHelperClass(String locallogoUrl,String visitorlogoUrl,String local,String date,int teamId,int localscore,int visitorscore,String teamName) {
    this.localscore = localscore;
    this.visitorscore = visitorscore;
    this.teamName = teamName;
    this.teamId = teamId;
    this.locallogoUrl = locallogoUrl;
    this.visitorlogoUrl = visitorlogoUrl;
    this.local = local;
    this.date = date;
}

    //Constructor
    public ResultsHelperClass() {
        this.localscore = 0;
    this.visitorscore = 0;
    this.teamId = 0;
    this.teamName = "";
    this.locallogoUrl = "";
    this.visitorlogoUrl = "";
    this.local = "";
    this.date = "";
    }

    protected ResultsHelperClass(Parcel in) {
        localscore = in.readInt();
        visitorscore = in.readInt();
        teamId = in.readInt();
        teamName = in.readString();
        locallogoUrl = in.readString();
        visitorlogoUrl = in.readString();
        local = in.readString();
        date = in.readString();
    }

    public static final Creator<ResultsHelperClass> CREATOR = new Creator<ResultsHelperClass>() {
        @Override
        public ResultsHelperClass createFromParcel(Parcel in) {
            return new ResultsHelperClass(in);
        }

        @Override
        public ResultsHelperClass[] newArray(int size) {
            return new ResultsHelperClass[size];
        }
    };

    //Getters
    public int getLocalscore() {
        return localscore;
    }

    public int getVisitorscore() {
        return visitorscore;
    }

    public String getTeamName() {
        return teamName;
    }

    public int getTeamId() {
        return teamId;
    }


    public String getLocal() {
        return local;
    }

    public String getDate() {
        return date;
    }

    public String getLocallogoUrl() {
        return locallogoUrl;
    }

    public String getVisitorlogoUrl() {
        return visitorlogoUrl;
    }

    //Setters
    public void setLocalscore(int localscore) {
        this.localscore = localscore;
    }

    public void setVisitorscore(int visitorscore) {
        this.visitorscore = visitorscore;
    }

    public void setTeamName(String teamName) {
        this.teamName = teamName;
    }

    public void setTeamId(int teamId) {
        this.teamId = teamId;
    }

    public void setLocallogoUrl(String locallogoUrl) {
        this.locallogoUrl = locallogoUrl;
    }

    public void setVisitorlogoUrl(String visitorlogoUrl) {
        this.visitorlogoUrl = visitorlogoUrl;
    }

    public void setLocal(String local) {
        this.local = local;
    }

    public void setDate(String date) {
        this.date = date;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writetoParcel(Parcel dest,int flags) {

        dest.writeString(teamName);
        dest.writeString(locallogoUrl);
        dest.writeString(visitorlogoUrl);
        dest.writeString(local);
        dest.writeString(date);
        dest.writeInt(localscore);
        dest.writeInt(visitorscore);
        dest.writeInt(teamId);

    }

    @Override
    public String toString() {
        return "ResultsHelperClass{" +
                "localscore=" + localscore +
                ",visitorscore=" + visitorscore +
                ",teamId=" + teamId +
                ",teamName='" + teamName + '\'' +
                ",locallogoUrl='" + locallogoUrl + '\'' +
                ",visitorlogoUrl='" + visitorlogoUrl + '\'' +
                ",local='" + local + '\'' +
                ",date='" + date + '\'' +
                '}';
    }
}

我先打印所选项目，然后再将其发送到Extra Intent：

@Override
    public void onGameClick(int position) {

        Intent in = new Intent(this,Team.class);
        System.out.println(listResults.get(position));
        in.putExtra("game",listResults.get(position));
        startActivity(in);
    }

这将为所选项目打印正确的值：

I / System.out：ResultsHelperClass {localscore = 0，visitorscore = 0，teamId = 1，teamName ='SéniorMasculí'，locallogoUrl ='https：//pitudev.com/sacabaneta/rivals/sacabaneta.jpg”， visitorlogoUrl ='https：//www.pitudev.com/sacabaneta/rivals/sonservera.jpg'，本地='1'，日期='2020-08-16 18：30：00.000000'

在新活动（团队）中，我这样做是从所选项目中检索数据：

if（getIntent（）。hasExtra（“ game”））{

    ResultsHelperClass selected_game = getIntent().getParcelableExtra("game");
    System.out.println(selected_game);

}

这将打印以下值：

I / System.out：ResultsHelperClass {localscore = 15，visitorscore = 15269971，teamId = 6881390，teamName ='null'，locallogoUrl ='null'，visitororlogoUrl ='null'，local ='null'，date =' null'}

这对我来说毫无意义，因为我已经检查过我传递了正确的值...如果有人可以帮助我，我将非常感激...谢谢

解决方法

已修复...

问题是writeToParcel（）和ResultsHelperClass（Parcel in）属性需要以相同的顺序...

希望这对以后的人有帮助！
