我有着名的BadParcelableException，但我看不出问题出在哪里，这是我的Parcelable课：

public class PaymentInfoViewModel implements Parcelable {

    private long idEstablishment;
    private String nameEstablishment;
    private int cardNumber;
    private double cardTotalValue;
    private String cardTotalValueDesc;
    private byte tipPercentage;

    public PaymentInfoViewModel() {
    }

    private static final Parcelable.Creator<PaymentInfoViewModel> CREATOR = new Parcelable.Creator<PaymentInfoViewModel>() {
        @Override
        public PaymentInfoViewModel createFromParcel(Parcel source) {
            return new PaymentInfoViewModel(source);
        }

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

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

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeLong(idEstablishment);
        dest.writeString(nameEstablishment);
        dest.writeInt(cardNumber);
        dest.writeDouble(cardTotalValue);
        dest.writeString(cardTotalValueDesc);
        dest.writeByte(tipPercentage);
    }

    public PaymentInfoViewModel(Parcel source) {
        setIdEstablishment(source.readLong());
        setNameEstablishment(source.readString());
        setCardNumber(source.readInt());
        setCardTotalValue(source.readDouble());
        setCardTotalValueDesc(source.readString());
        setTipPercentage(source.readByte());
    }
//getters/setters

}

它放在这里，在我的适配器内点击事件：

    PaymentInfoViewModel p = new PaymentInfoViewModel();
    p.setIdEstablishment(item.getIdEstablishment());
    p.setNameEstablishment(item.getName());
    p.setTipPercentage((byte)0);
    p.setCardTotalValueDesc("");
    p.setCardTotalValue(0);
    p.setCardNumber(0);

    Intent intent = new Intent(context, CardNumberActivity.class);
    intent.putExtra(ConstantsUtils.PARAM_INTENT_PAYMENT_INFO, p);

    context.startActivity(intent);

以及我如何尝试上课：

PaymentInfoViewModel paymentInfoViewModel = getIntent().getParcelableExtra(ConstantsUtils.PARAM_INTENT_PAYMENT_INFO);

我以前检查过这些链接，但找不到解决方案：

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

将对象从 Activity 传递给另一个时出错（使用 Parcelable）

编辑：这是错误（当我尝试时发生getParcelableExtra）：

如果您还不知道，您可能会对 Parceler 库感兴趣（尽管您现在已经解决了您的问题）：https ://github.com/johncarl81/parceler

（如果我有声誉，我会发表评论）

经过几个小时的工作并尝试了很多东西，我终于设法修复了它，而且它真的很简单，该属性CREATOR无法拥有它的访问器private，我将其更改为public并且它有效！

在我的情况下

我只是简单地删除了旧的 Parcelable 接口代码并实现了新的 Parcelable 接口代码。

它对我有用..

*编辑

确保您的 Parcelable 类是静态的。
