• Android Studio 优秀插件: Parcelable Code Generator


    这里假设我们已经会使用 Parcelable 序列化一个对象了~~

    那么大家会发现 Parcelable 使用起来有些复杂,因为我们要自己复写 几个方法,而且当类的属性比较多的时候,我们就会难受了,又要注意不写错属性名,又要注意写对属性的类型,又要花不少的时间做重复的事情。

    那么因为 Parcelable 有使用它的优势,我们又不能放弃,那该怎么办么?

    Android Studio 提供给了我们 一个插件用来简化 给一个类 实现 Parcelable 接口的流程。

    -----------------------------------------------------------------------------

    现在学习下如何使用这个插件:

    1、Android Studio 打开一个项目,点击左上角 File -->Settings... 进行设置

    2、选择插件Plugins , 搜索Parcel,如果你没有下载过这个插件,那么搜索框下面会显示“Nothing to show.Click Browse to....”

    3、那就点击蓝色字体的 Browse 吧  ,这个时候会出现如下图的界面,我们只需要在左边选中arcel然后点击右面 绿色按钮 "Install plugin" 就可以了

    4、完成了上面三个步骤,就可以使用Parcelable Code Generator插件了

    怎么用呢,

    (1)创建一个类文件,类名是看你需求自定义写的,添加上你需要的属性

    (2)快捷键 alt+insert ,会出现如下选择框,选择Parcelable 即可

    然后我们就看到代码,是不是比我们手动写要快的许多

    public class People implements Parcelable {
    
    
        private int id;
        private String url;
        private int width;
        private int height;
        private int likeCount;
        private String description;
        private int time;
        private int replyCount;
        private int floorCount;
        private int likeUserCount;
        private int age;
        private String name;
        private String school;
        private int type;
        private String sax;
        private int userid;
    
    
        @Override
        public int describeContents() {
            return 0;
        }
    
        @Override
        public void writeToParcel(Parcel dest, int flags) {
            dest.writeInt(this.id);
            dest.writeString(this.url);
            dest.writeInt(this.width);
            dest.writeInt(this.height);
            dest.writeInt(this.likeCount);
            dest.writeString(this.description);
            dest.writeInt(this.time);
            dest.writeInt(this.replyCount);
            dest.writeInt(this.floorCount);
            dest.writeInt(this.likeUserCount);
            dest.writeInt(this.age);
            dest.writeString(this.name);
            dest.writeString(this.school);
            dest.writeInt(this.type);
            dest.writeString(this.sax);
            dest.writeInt(this.userid);
        }
    
        public People() {
        }
    
        protected People(Parcel in) {
            this.id = in.readInt();
            this.url = in.readString();
            this.width = in.readInt();
            this.height = in.readInt();
            this.likeCount = in.readInt();
            this.description = in.readString();
            this.time = in.readInt();
            this.replyCount = in.readInt();
            this.floorCount = in.readInt();
            this.likeUserCount = in.readInt();
            this.age = in.readInt();
            this.name = in.readString();
            this.school = in.readString();
            this.type = in.readInt();
            this.sax = in.readString();
            this.userid = in.readInt();
        }
    
        public static final Parcelable.Creator<People> CREATOR = new Parcelable.Creator<People>() {
            public People createFromParcel(Parcel source) {
                return new People(source);
            }
    
            public People[] newArray(int size) {
                return new People[size];
            }
        };
    }
