public interface Parcelable
{//内容描述接口，基本不用管public int describeContents();//写入接口函数，打包public void writeToParcel(Parcel dest, int flags);//读取接口，目的是要从Parcel中构造一个实现了Parcelable的类的实例处理。因为实现类在这里还是不可知的，所以需要用到模板的方式，继承类名通过模板参数传入//为了能够实现模板参数的传入，这里定义Creator嵌入接口,内含两个接口函数分别返回单个和多个继承类实例public interface Creator<T> {public T createFromParcel(Parcel source);public T[] newArray(int size);}
