Parcelable 对象错误:在偏移量 *** 处解组未知类型代码 *** [英] Error with Parcelable object: Unmarshalling unknown type code *** at offset ***
本文介绍了Parcelable 对象错误:在偏移量 *** 处解组未知类型代码 ***的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试为学校完成这个项目，但我在 Parcelable 代码的读取"部分不断收到此错误.这已经占用了我一天的很多时间，我已经阅读了无数具有类似问题的 StackOverflow 页面，但这些解决方案都不适合我.
I'm trying to finish this project for school and I keep getting this error in the 'read' portion of my Parcelable code. This has eaten up many hours of my day and I've read countless StackOverflow pages with similar problems and none of those solutions worked for me.
以下是我读过但似乎不是问题的内容:
Here are things I've read about and doesn't seem to be the issue:
- Proguard(因为我没有使用)
- Android Studio 是最新的
- 读"和写"类型不匹配
- 'read'和'write'部分中对象参数的顺序
抛出错误的行:
this.quantity = ((float) in.readValue((float.class.getClassLoader())));
这是自定义类:
public class Ingredient implements Parcelable {
@SerializedName("quantity")
@Expose
private float quantity;
@SerializedName("measure")
@Expose
private String measure;
@SerializedName("ingredient")
@Expose
private String ingredient;
private Ingredient(Parcel in) {
this.quantity = ((float) in.readValue((float.class.getClassLoader())));
this.measure = ((String) in.readValue((String.class.getClassLoader())));
this.ingredient = ((String) in.readValue((String.class.getClassLoader())));
}
public void writeToParcel(Parcel dest, int flags) {
dest.writeValue(quantity);
dest.writeValue(measure);
dest.writeValue(ingredient);
}
/**
* No args constructor for use in serialization
*/
@SuppressWarnings("unused")
public Ingredient() {
}
/**
* @param measure
* @param ingredient
* @param quantity
*/
@SuppressWarnings("JavaDoc")
public Ingredient(float quantity, String measure, String ingredient) {
super();
this.quantity = quantity;
this.measure = measure;
this.ingredient = ingredient;
}
public static final Creator<Ingredient> CREATOR = new Creator<Ingredient>() {
@Override
public Ingredient createFromParcel(Parcel in) {
return new Ingredient(in);
}
@Override
public Ingredient[] newArray(int size) {
return new Ingredient[size];
}
};
public float getQuantity() {
return quantity;
}
public String getMeasure() {
return measure;
}
public String getIngredient() {
return ingredient;
}
public int describeContents() {
return 0;
}
这里是堆栈跟踪:

我根据 Ben 在下面的回复更新了我的代码.我在堆栈跟踪中收到一条新的错误消息，并且我返回一个数组大小为7667790"的数组，该数组应该大约为12".
I updated my code based on Ben's response below. I get a new error message in the stack trace and I'm getting back an array size of '7667790' for an array that should be about '12'.

推荐答案
发现问题！这是我使用的第 3 方库之一.我不得不阅读所有的库文档，我发现我需要将一些特定于库的代码添加到我的对象类的可打包代码中.
Found the issue! It was something with one of the 3rd party libraries I was using. I had to read all the library documentation and I found that I needed to add some library specific code to the parcelable code of my object class.
这篇关于Parcelable 对象错误:在偏移量 *** 处解组未知类型代码 ***的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
