Android 在解组父视图SavedState时，还原视图SavedState会引发ClassNotFoundException

我有两个班

ParentClass

和

ChildClass

：

ParentClass

是RelativeLayout的子类，它使用onSaveInstanceState（）/onRestoreInstanceState（）和以下代码保存状态：

@Override
protected Parcelable onSaveInstanceState() {
    SavedState savedState = new SavedState(super.onSaveInstanceState());
    savedState.someObj = someObj;
    savedState.someInt = someInt;
    savedState.someEnum = someEnum;
    return savedState;
}

@Override
protected void onRestoreInstanceState(Parcelable in) {
    if (!(in instanceof SavedState)) {
        super.onRestoreInstanceState(in);
        return;
    }
    SavedState savedState = (SavedState) in;
    super.onRestoreInstanceState(savedState.getSuperState());
    this.someObj = savedState.someObj;
    this.someInt = savedState.someInt;
    this.someEnum = savedState.someEnum;
}

下面是

SavedState

代码：

public static class SavedState extends BaseSavedState {

    private SomeObj someObj;
    private int someInt;
    private SomeEnum someEnum;

    public SavedState(Parcelable superState) {
        super(superState);
    }

    public SavedState(Parcel source) {
        super(source);
        someInt = source.readInt();
        someEnum = SomeEnum.values()[source.readInt()];
        someObj = source.readParcelable(SomeObj.class.getClassLoader());
    }

    @Override
    public void writeToParcel(@NonNull Parcel dest, int flags) {
        super.writeToParcel(dest, flags);
        dest.writeInt(someInt);
        dest.writeInt(someEnum.ordinal());
        dest.writeParcelable(someObj, flags);
    }

    public static final Creator<SavedState> CREATOR = new Creator<SavedState>() {
        public SavedState createFromParcel(Parcel in) {
            return new SavedState(in);
        }

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

使您的SavedState类实现可打包

public static class SavedState extends Parcelable {

---

SavedState

扩展

BaseSavedState

它扩展了

AbsSavedState

它实现了

Parcelable

，所以我认为它不会有帮助！你找到解决办法了吗？谢谢

public static class SavedState extends Parcelable {
