내부에 객체가있는 클래스를 어떻게 분할 할 수 있습니까?

Question

필자는 parcelable 클래스를 만들고 싶지만, 변수 중 하나는 또 다른 객체이기 때문에 이것을 관리하는 방법을 모른다.

public class CloseItPending implements Parcelable { 

    @Key 
    int id; 

    @Key 
    CategoryDate date; 

    @Key 
    String service; 

    @Key 
    String characteristics; 

    @Key 
    String buydate; 

    @Key 
    String payingmethod; 

    @Key 
    String price; 

    @Key 
    String others; 

    @Key 
    int servicecompanychange; 

    @Key 
    int characteristicscompanychange; 

    @Key 
    int buydatecompanychange; 

    @Key 
    int payingmethodcompanychange; 

    @Key 
    int pricecompanychange; 

    @Key 
    int otherscompanychange; 

    @Key 
    int validate_user; 

    @Key 
    int validate_company; 

    ... 

두 번째 변수는 date이며 유형은 CategoryDate입니다.

다음 방법은 어떻게되어야합니까?

public int describeContents() 

public void writeToParcel(Parcel dest, int flags) 

도움 주셔서 감사합니다.

가능성을 다음 CategoryDate 클래스는 당신의 하나입니다

public class CloseItPending implements Parcelable { 

    @Key 
    int id; 

    @Key 
    CategoryDate date; 

    @Key 
    String service; 

    @Key 
    String characteristics; 

    @Key 
    String buydate; 

    @Key 
    String payingmethod; 

    @Key 
    String price; 

    @Key 
    String others; 

    @Key 
    int servicecompanychange; 

    @Key 
    int characteristicscompanychange; 

    @Key 
    int buydatecompanychange; 

    @Key 
    int payingmethodcompanychange; 

    @Key 
    int pricecompanychange; 

    @Key 
    int otherscompanychange; 

    @Key 
    int validate_user; 

    @Key 
    int validate_company; 

    public CloseItPending() {

    public CloseItPending(int id, CategoryDate date, String service, String characteristics, String buydate, String payingmethod, String price, String others, int servicecompanychange, int characteristicscompanychange, int buydatecompanychange, int payingmethodcompanychange, int pricecompanychange, int otherscompanychange, int validate_user, int validate_company) {

Answer 1

경우, 당신은뿐만 아니라 그것을 Parcelable 할 수 있습니다. 그런 다음 CloseItPending 클래스에서 'writeToParcel() 전화를 걸면 this.date.writeToParcel()으로 전화를 걸고 동일한 Parcel 개체를 전달할 수 있습니다. 이렇게하면 CategoryDate 클래스가 CloseItPending에서 사용중인 동일한 Parcel 개체에 데이터를 쓸 수 있습니다. 난이 도움을 희망
