Question

我收到错误android.os.BadParcelableException: Parcelable protocol requires a Parcelable.Creator object called CREATOR，但它只是偶尔随机发生。我不知道为什么有时它会导致应用程序崩溃，有时候它不会崩溃。

在我的对象类中，我的writeToParcel方法是完全空的，我认为这可能与它有关。

@Override
public void writeToParcel(Parcel dest, int flags) {
    // TODO Auto-generated method stub


}

我通过parcelable对象传递的变量类型是boolean，string，int，string arraylist，boolean array，以及我制作的另一个parcelable对象的arraylist。

关于导致偶然崩溃的原因的任何想法？

你错过了一个Parcelable.Creator。您必须在对象中添加创建者

public static final Parcelable.Creator<YourObject> CREATOR = new Creator<YourObject>() {
    @Override
    public YourObject[] newArray(int size) {
        // TODO Auto-generated method stub
        return new YourObject[size];
    }

    @Override
    public YourObject createFromParcel(Parcel source) {
        // TODO Auto-generated method stub
        return new YourObject(source);
    }
};

BadParcelable异常偶尔导致应用程序崩溃
