可打包协议需要一个名为CREATOR的Parcelable.Creator对象（我确实有CREATOR）

Question

我正在尝试将Parcelable数据从一种意图传递到另一种意图，这是我得到的错误：

08-31 14:12:22.709: E/AndroidRuntime(9931): FATAL EXCEPTION: main
08-31 14:12:22.709: E/AndroidRuntime(9931): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.matejsoftware.cardscoretracker/com.matejsoftware.cardscoretracker.Igra}: android.os.BadParcelableException: Parcelable protocol requires a Parcelable.Creator object called  CREATOR on class com.matejsoftware.cardscoretracker.Novaigra$Player

事情是：我确实有Parcelable.Creator对象。我将在下面发布整个Parcelable代码：

public class Player implements Parcelable{
    String name;
    int score;
    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeInt(score);
    }

    public Player(Parcel source){
        score = source.readInt();
        name = source.readString();
    }

    public Player(int score, String name){
        this.score = score;
        this.name = name;
    }
}

public class MyCreator implements Parcelable.Creator<Player> {

    @Override
    public Player createFromParcel(Parcel source) {
        return new Player(source);
    }

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

}

创建者有什么问题吗？单击按钮以开始下一个活动时，应用程序崩溃。

这是我在第二个活动中“检索” Parcelable数据的方式：

//global variable
ArrayList<Player> playersParceledData;

//This is in onCreate
playersData = getIntent();
playersParceledData = playersData.getParcelableArrayListExtra("parceledData");

另外，这就是我将类对象放入ParcelableArrayListExtra的方式：

Player newPlayer = new Player(0, text);
playersParceledData.add(newPlayer);
zacniIgro.putParcelableArrayListExtra("parceledData", playersParceledData);

从包裹中读取的顺序与您输入的顺序不同。

在writeToParcel()你第一次把字符串，但在HeatFriendDetail(Parcel in)，你先读整数。这不是正确的方法，因为顺序或读/写很重要。

以下是在与包裹之间进行数据读写的正确顺序的代码（另请参见此链接）：

public class FriendDetail implements Parcelable {

    private String full_name;
    private int privacy;

    public HeatFriendDetail(Parcel in) {
        this.full_name = in.readString();
        this.privacy = in.readInt();
    }

    public HeatFriendDetail() {

    }

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

        dest.writeString(this.full_name);
        dest.writeInt(this.privacy);
    }

    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public HeatFriendDetail createFromParcel(Parcel in) {
            return new HeatFriendDetail(in);
        }

        public HeatFriendDetail[] newArray(int size) {
            return new HeatFriendDetail[size];
        }
    };

    // GETTER SETTER//
}
