Android 序列化模板

序列化方式

1. implements Serializable
2. implements Parcelable

Serializable 模板

一般继承 Serializable 就行了

public class SerializableBean implements Serializable {

}

Parcelable 模板

ParcelableBean

public class ParcelableBean implements Parcelable {
    
    private int id;
    private String answer;
    public ParcelableChlidBean parcelableObjiect;
    public ParcelableChlidBean[] parcelableArray;
    public List<ParcelableChlidBean> parcelableList;
    public String[] stringArray;
    
    protected ParcelableBean() {
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeInt(id);
        dest.writeString(answer);
        dest.writeParcelable(parcelableObjiect, flags);
        dest.writeParcelableArray(parcelableArray, flags);
        dest.writeTypedList(parcelableList);
        dest.writeStringArray(stringArray);
    }

    protected ParcelableBean(Parcel in) {
        id = in.readInt();
        answer = in.readString();

                    parcelables.length, ParcelableChlidBean[].class);
        }

        // Creator<PhotoImageItem> c),这里 list不能为空，
        // 否则回报 NullPointException

            parcelableList = new ArrayList<ParcelableChlidBean>();
        }
        in.readTypedList(parcelableList, ParcelableChlidBean.CREATOR);
        // 注：这里为什么是parcel.createStringArray()
        // 而不是 parcel.readStringArray(selectedImage)？
        stringArray = in.createStringArray();
    }

    public static final Creator<ParcelableBean> CREATOR = new Creator<ParcelableBean>() {

        }
    };

    @Override

        return 0;
    }
