我遇到了一些Parcelable自定義類的問題，我正在使用這個自定義類來安裝Android應用程序，而我已經設法以非常奇怪的方式解決這個問題。Android Parcelable訂單
我只在幾個特定的情況下從一個parcelable讀取時發生了崩潰（這導致我認爲我的實現並非完全錯誤）。

這是我原來實行的崩潰是在（Ad.java）存在的模型
public class Ad implements Parcelable {
public String author;
public String transporter;
public Image cover_urls;
public String details;
public String id;
public int item_size;
public String object_name;
public Money tips;
public Money price;
public Location where_to_buy;
public String resource_uri;
public Location where_to_deliver;
public Permissions permissions;
public TransportOffer[] transport_offers;
public float fees_lemonway_CB;
public String validation_code;
public Date creation_dtime;
public String accepted_transport_offer_id;
protected Ad(Parcel in) {
author = in.readString();
transporter = in.readString();
details = in.readString();
id = in.readString();
item_size = in.readInt();
object_name = in.readString();
resource_uri = in.readString();
cover_urls = in.readParcelable(Image.class.getClassLoader());
tips = in.readParcelable(Money.class.getClassLoader());
price = in.readParcelable(Money.class.getClassLoader());
permissions = in.readParcelable(Permissions.class.getClassLoader());
transport_offers = in.createTypedArray(TransportOffer.CREATOR);
where_to_buy = in.readParcelable(Location.class.getClassLoader());
where_to_deliver = in.readParcelable(Location.class.getClassLoader());
fees_lemonway_CB = in.readFloat();
validation_code = in.readString();
creation_dtime = (Date) in.readSerializable();
accepted_transport_offer_id = in.readString();
}
public static final Creator<Ad> CREATOR = new Creator<Ad>() {
@Override
public Ad createFromParcel(Parcel in) {
return new Ad(in);
}
@Override
public Ad[] newArray(int size) {
return new Ad[size];
}
};
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(author);
dest.writeString(transporter);
dest.writeString(details);
dest.writeString(id);
dest.writeInt(item_size);
dest.writeString(object_name);
dest.writeString(resource_uri);
dest.writeParcelable(cover_urls, flags);
dest.writeParcelable(tips, flags);
dest.writeParcelable(price, flags);
dest.writeParcelable(permissions, flags);
dest.writeTypedArray(transport_offers, flags);
dest.writeParcelable(where_to_buy, flags);
dest.writeParcelable(where_to_deliver, flags);
dest.writeFloat(fees_lemonway_CB);
dest.writeString(validation_code);
dest.writeSerializable(creation_dtime);
dest.writeString(accepted_transport_offer_id);
}
}的
我設法通過改變讀取爲了解決該問題/寫一些Parcelable屬性。 我現在正在讀/寫where_to_buy和where_to_deliver在cover_urls之前似乎已經解決了問題。
where_to_buy = in.readParcelable(Location.class.getClassLoader());
where_to_deliver = in.readParcelable(Location.class.getClassLoader());
cover_urls = in.readParcelable(Image.class.getClassLoader());
tips = in.readParcelable(Money.class.getClassLoader());
price = in.readParcelable(Money.class.getClassLoader());
permissions = in.readParcelable(Permissions.class.getClassLoader());
transport_offers = in.createTypedArray(TransportOffer.CREATOR);
（在writeToParcel中的順序是相同的，我只是通過不粘貼它在這裏保存幾行）。
這個奇怪的修復工作就像一個魅力，我不知道爲什麼。
有沒有人遇到類似的東西或知道爲什麼包裝/拆包的順序會影響結果？
乾杯！
