Android Parceling an object with

1、场景：

• Bundle
• RoomDatabase

2、注意事项：

• write 和 read 的顺序一定要对应

3、代码如下

public class Note implements Parcelable {

    private int noteId;

    private JSONArray images;

    public int getNoteId() {
        return noteId;
    }

    public JSONArray getImages() {
        return images;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int i) {
        dest.writeInt(noteId);
        dest.writeString(this.images != null ? this.images.toString() : "[]");
    }

    protected Note(Parcel in) {
        noteId = in.readInt();
        String tempImages = in.readString();
        try {
            images = new JSONArray(tempImages != null ? tempImages :"[]");
        } catch (JSONException e) {
            images = new JSONArray();
        }
    }

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

        @Override
        public Note[] newArray(int size) {
            return new Note[size];
        }
    };
}
