공유 Parcelable 객체

Question

안녕하세요 다음과 같은 활동에 조각에서 개체를 전달하려고 :

Intent intent = getIntent(); 
Bundle bundle = intent.getExtras(); 
company = bundle.getParcelable("company"); 

그리고 내가 시도 :

Bundle bundle1 = new Bundle(); 
bundle1.putParcelable("company", companies.get(i)); 
Intent intent = new Intent(getActivity(), CompanyInfoActivity.class); 
intent.putExtras(bundle1); 
getActivity().startActivity(intent); 

그리고 활동에

내가 다음에 할

을

Intent intent = new Intent(getActivity(), CompanyInfoActivity.class); 
      intent.putExtra("company",companies.get(i)); 
      getActivity().startActivity(intent); 

및 활동 내역 :

Intent intent = getIntent(); 
    company = intent.getParcelableExtra("company"); 
    tvName.setText(company.getName()); 

그리고 company은 내가 얻은 후 null 입력란을 사용합니다. 내가 보낸 객체가 null 필드가 아니라고 확신합니다.

내 Company.class

public class Company implements Parcelable { 

private int uid; 
@SerializedName("field_user_org_name_value") 
private String name; 
@SerializedName("field_user_org_address_value")

private int category; 
@SerializedName("field_user_org_town_tid") 
private int cityId;

당신은 당신의 조각과 활동 사이에서 통신 할 수있는 수신기를 만들 수 있습니다

Answer 1

의

public Company(Parcel in) { 
    in.writeInt(uid); 
    in.writeString(name); 
    in.writeString(address); 
    in.writeInt(category); 
    in.writeInt(cityId); 
    in.writeString(imageUrl); 
    in.writeInt(online); 
    in.writeString(description); 
    in.writeString(mobPhone); 
    in.writeString(phone); 
    in.writeDouble(lat); 
    in.writeDouble(lng); 
    in.writeDouble(distance); 

} 

당신은 소포의 값을 읽어야

uid = in.readInt(); 

등

에를

Answer 2

:

public interface CompanyListener 
{ 
    public void sendCompany(Company company); 
} 

다음, 당신의 조각에 당신은 만들 필요가 이 청취자의 인스턴스

private CompanyListener companyListener; 

@Override 
public void onAttach(Activity activity) 
{ 
    super.onAttach(activity); 
    this.companyListener = (YourActivity) activity; 
} 

@Override 
public void onDetach() 
{ 
    super.onDetach(); 
    this.companyListener = null; 
} 

지금 당신은 당신의 활동을 구현해야 다음 OnAttach에서

당신은 그것을 인스턴스화하고 OnDetach에서 그것을 uninstantiate해야합니다.

또한 당신이 Otto library from Square를 사용할 수 있지만, 코드의이 작품에서 더 복잡 :

Answer 3

구현에 문제가 있습니다.- 특히 당신의 Parcel 생성자 :

public Company(Parcel in) { 
    in.writeInt(uid); 
    in.writeString(name); 
    ... 
} 

당신이 작성하는 필드 생성자에서 Parcel합니다. 이것은 당신이 Parcel에서 데이터를으로 읽어 들여야하는 지점입니다. 예를 들어 :

public Company(Parcel in) { 
    uid = in.readInt(); 
    name = in.readString(); 
    ... 
}
