Android - 包裹:无法编组价值
问题描述:
我正在尝试使用 Parcelable 通过活动传递数据.这是我的代码:
I'm trying to pass data through activities with Parcelable. This is my code :
public class Player implements Parcelable {
public static final Parcelable.Creator<Player> CREATOR = new Parcelable.Creator<Player>() {
public Player createFromParcel(Parcel in) {
return new Player(in);
}
public Player[] newArray(int size) {
return new Player[size];
}
};
private String name;
private List<Card> listCards;
public Player(String namePlayer) {
name = namePlayer;
listCards = new ArrayList<>();
}
private Player(Parcel in) {
// This order must match the order in writeToParcel()
name = in.readString();
in.readList(listCards, null);
// Continue doing this for the rest of your member data
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeList(listCards);
}
每当我运行此代码时,都会出现错误:
Whenever I run this code, I get the error :
java.lang.RuntimeException: Parcel: unable to marshal value com.antoinedelia.lebarbu_versionalcool.Card@ec54bb
您知道可能是什么问题吗?
Do you have any idea what could be the problem?
谢谢
答
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeList(listCards);
}
因为Card
类没有实现Parcelable
,所以你不能做writeList/readList
.它仅适用于 Parcelable
对象列表.
Since Card
class does not implement Parcelable
you cannot do writeList/readList
. It is only applicable for List of Parcelable
Objects.
