Question

我已为Parcelable实施了RealEstateAd界面。但是，我的数据在活动之间的每次转移中都会被破坏。

初始数据（将传递给活动＃2）：

classOfProperty = 101
typeOfAd = 102 <-- Note this value.
typeOfAdvertiser = 101
typeOfProperty = 101

活动＃2中收到的数据：

classOfProperty = 101
typeOfAd = 101 <-- It should be 102
typeOfAdvertiser = 101
typeOfProperty = 102 <-- It should be 101

我的Parcelable实施：

// Parcelable implementation

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

@Override
public void writeToParcel(Parcel out, int flags) {
    out.writeString(uid);
    out.writeString(id);

    out.writeInt(status);

    out.writeString(publishDate);
    out.writeString(modifiedDate);

Answer 1

似乎 hits 的值在writeToParcel方法中写为Long，但在Parcel构造函数中读为 Int 。

我使用Parcelable实现损坏了数据
