如何编写List<>进入包裹 [英] How to write List<> into parcel

问题描述

public class Category implements Parcelable {

    private int mCategoryId;
    private List<Video> mCategoryVideos;

 public int getCategoryId() {
        return mCategoryId;
    }

    public void setCategoryId(int mCategoryId) {
        this.mCategoryId = mCategoryId;
    }

 public List<Video> getCategoryVideos() {
        return mCategoryVideos;
    }

    public void setCategoryVideos(List<Video> videoList) {
        mCategoryVideos = videoList;
    }

@Override
    public void writeToParcel(Parcel parcel, int i) {
        parcel.writeInt(mCategoryId);
        parcel.writeTypedList(mCategoryVideos);
    }

    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public Category createFromParcel(Parcel parcel) {
            final Category category = new Category();

            category.setCategoryId(parcel.readInt());
            category.setCategoryVideos(parcel.readTypedList()); */// **WHAT SHOULD I WRITE HERE***

            return category;
        }

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

}

我的代码是我正在使用从parcelable实现的模型...谁能告诉他们我在这一行中写了什么喊叫 category.setCategoryVideos(parcel.readTypedList())我找不到任何有用的帖子.

Im my code I am using model which implements from parcelable...Could anyone tell em what shout I write in this line category.setCategoryVideos(parcel.readTypedList()) I couldn't find any helpful post.

category.setCategoryVideos(parcel.readTypedList(mCategoryVideos，Video.CREATOR)); 在这里，我无法解决错误的mCategoryVideos.

category.setCategoryVideos(parcel.readTypedList(mCategoryVideos,Video.CREATOR)); in here mCategoryVideos I have cannot resolve error.

推荐答案

Parcelable类有一些列表方法，您可以在这里查看它们:

There are list methods for Parcelable class, you can take a look at them here:

readList(列出outVal，ClassLoader加载程序)

writeList(列表值)

在您的情况下，它看起来像:

In your case it would look like:

List<Object> myList = new ArrayList<>();

parcel.readList(myList,List.class.getClassLoader());
category.setCategoryVideos(myList);
