Android | java.lang.RuntimeException: Parcel Android .os.Par

Question

请问如何解决这个问题?

Parcelable接口i在客户pojo对象中实现。请告诉我如何在活动2中读取客户对象?

Customer.java

public Customer implements Parcelable{
    private String name;
    private String phone;
    private List<AccountDetails> accoutDetails;
/getter and setters
public int describeContents() {
    return 0;
}
public Customer(Parcel in) {
    name= in.readString();
    phone= in.readString();
    accoutDetails= new ArrayList<AccountDetails>();
    in.readList(accoutDetails,null);

}
public static final Parcelable.Creator<Customer> CREATOR = new Parcelable.Creator<Customer>() {
    public Customer createFromParcel(Parcel in) {
        return new Customer(in);
    }
    public Customer[] newArray(int size) {
        return new Customer[size];
    }
};
@Override
public void writeToParcel(Parcel dest, int arg1) {
    // TODO Auto-generated method stub
    dest.writeString(this. name);
    dest.writeString(this.phone);
    dest.writeList(accoutDetails);
}
}

在活动1中使用如下代码:

Customer selected_row=(Customer) parent.getAdapter().getItem(position);
Intent intent = new Intent(getApplicationContext(), Activity2.class);
Bundle bundle = new Bundle();
bundle.putParcelable("selected_customer", selected_row);
intent.putExtras(bundle);
startActivity(intent);

活动2:

 Customer cust_object = getBundle.getParcelable("selected_customer");

请告诉我如何在活动2中读取客户对象

Answer 1

虽然支持序列化，但不建议用于Android。请看这篇文章。

我认为你的问题在这行代码上:

in.readList(accoutDetails,null);

因为accountDetails是一个自定义accountDetails对象的列表，你需要accountDetails也实现Parcelable。

这样做，然后将上面的代码行改为:

in.readTypedList(accoutDetails, AccountDetails.CREATOR);

同时,改变:

public Customer(Parcel in) {
    name= in.readString();
    phone= in.readString();
    accoutDetails= new ArrayList<AccountDetails>();
    in.readTypedList(accoutDetails,null);
}

:

public Customer(Parcel in) {
    name= in.readString();
    phone= in.readString();
    in.readTypedList(accoutDetails, AccountDetails.CREATOR);
}

和变化:

@Override
public void writeToParcel(Parcel dest, int arg1) {
    // TODO Auto-generated method stub
    dest.writeString(this. name);
    dest.writeString(this.phone);
    dest.writeList(accoutDetails);
}

:

@Override
public void writeToParcel(Parcel dest, int arg1) {
    dest.writeString(this.name);
    dest.writeString(this.phone);
    dest.writeTypedList(accoutDetails);
}

编辑2

public Customer implements Parcelable{
    private String name;
    private String phone;
    private List<AccountDetails> accoutDetails = new ArrayList<AccountDetails>();
