將對象發送到其他活動時發生異常類型

Question

我嘗試使用Intent發送一個對象。

我有三個班，A班有一個班級B的列表，B班有一個班級C的列表，我想從一個活動發送班級A到另一個班級 Parcelable。 我嘗試以下代碼：

在A類：

在B類

private List<DocumentItem> documentItems; 
private int DocNum ; 

    public CycleAccount(Parcel in) { 
    DocNum = in.readInt(); 
    documentItems = new ArrayList<DocumentItem>(); 
    in.readList(documentItems , null); 
} 

@Override 
public int describeContents() { 
    return 0; 
} 
@Override 
public void writeToParcel(Parcel dest, int flags) { 

    dest.writeInt(DocNum); 
    dest.writeList(documentItems); 


} 

public CycleAccount(Parcel in) { 
    DocNum = in.readInt(); 
    documentItems = new ArrayList<DocumentItem>(); 
    in.readList(documentItems , null); 
} 

：

private String LedgerAcountId; 
private String Title; 
private String Debit; 
private String Credit; 
private String Description; 
private List<DetailsAccount> DetailAccount; 


public DocumentItem(Parcel in) { 
    LedgerAcountId = in.readString(); 
    Title = in.readString(); 
    Debit = in.readString(); 
    Credit = in.readString(); 
    Description = in.readString(); 

    DetailAccount = new ArrayList<DetailsAccount>(); 
    in.readList(DetailAccount, null); 


} 

@Override 
public int describeContents() { 

    return 0; 
} 
@Override 
public void writeToParcel(Parcel dest, int flags) { 
    dest.writeString(LedgerAcountId); 
    dest.writeString(Title); 
    dest.writeString(Debit); 
    dest.writeString(Credit); 
    dest.writeString(Description); 
    dest.writeList(DetailAccount); 

} 

，並在類C：

private String Title; 
private String Level; 
private String detailAccountId; 


DetailsAccount(Parcel in) 
{ 
    Title = in.readString(); 
    Level = in.readString(); 
    detailAccountId = in.readString(); 
} 

@Override 
public int describeContents() { 

    return 0; 
} 
@Override 
public void writeToParcel(Parcel dest, int flags) { 

    dest.writeString(Title); 
    dest.writeString(Level); 
    dest.writeString(detailAccountId); 
} 

和用於發送和獲取數據我使用以下代碼：

發送：

Intent intent = new Intent(AccountReviewActivity.this, CycleAccountAccountReview.class); 
Bundle bundle = new Bundle(); 
bundle.putParcelable("data", CycleItems); 
intent.putExtra("data",bundle); 
startActivity(intent); 

獲取：

cycleItem = new CycleAccount(); 
Bundle bundle = getIntent().getExtras(); 
cycleItem = bundle.getParcelable("data"); 

，我得到以下錯誤：

什麼想法？

編輯

CycleItems = new CycleAccount(); 
documentItemResponse = JsonAcountReview.getAccountItem(params[0] ,params[1],params[2],params[3],params[4],params[5]); 
CycleItems = JsonAcountReview.AccountItem(documentItemResponse); 

我從Json

Answer 1

數據試試這個...

Intent intent = new Intent(AccountReviewActivity.this, CycleAccountAccountReview.class); 
intent.putExtra("data",cycleItems); 
startActivity(intent); 

並在收到活動

CycleAccount cycleItem = getIntent().getParcelableExtra("data");
