傳遞的JavaMail消息的HashMap來Android的活動

Question

我做的，我有存儲/恢復數據是JavaMail的消息的HashMap的，但我收到以下錯誤Android應用程序：

MailActivity.java

In onSaveInstanceState, I am saving my hashmap in a SimpleParcelable class. The code for saving and restoring is :

@Override 
    protected void onSaveInstanceState(Bundle outState) { 
     Log.i("mustang", "Saving activity states. size : " + emailsMap.size()); 
     if(emailsMap.size() > 0) 
     { 
      outState.putParcelable("parcel", new SimpleParcelable(emailsMap)); 
     } 

     super.onSaveInstanceState(outState); 
    } 

    @Override 
    protected void onRestoreInstanceState(Bundle state) { 
     // TODO Auto-generated method stub 

     Log.i("mustang", "Restoring activity states."); 

     super.onRestoreInstanceState(state); 

     SimpleParcelable stateParcel = state.getParcelable("parcel"); 
     emailsMap = (HashMap<String, Message[]>)stateParcel.getEmailsMap(); 
     this.emailsFetched(emailsMap.get("INBOX"), "INBOX", TaskType.NONE); 
    } 

而序列化代碼SimpleParcelable是：

public class SimpleParcelable implements Parcelable{ 
    private final Map<String, Message[]> emailsMap; 
    public SimpleParcelable(HashMap<String, Message[]> messages) 
    { 
     emailsMap = messages; 
    } 

    public static final Parcelable.Creator<SimpleParcelable> CREATOR 
     = new Parcelable.Creator<SimpleParcelable>() { 

      @Override 
      public SimpleParcelable createFromParcel(Parcel source) { 
       Bundle rBundle = source.readBundle(); 
       return new SimpleParcelable((HashMap<String, Message[]>)rBundle.getSerializable("map")); 
      } 

      @Override 
      public SimpleParcelable[] newArray(int size) { 
       // TODO Auto-generated method stub 
       return new SimpleParcelable[size]; 
      } 
     }; 
    @Override 
    public int describeContents() { 
     // TODO Auto-generated method stub 
     return 0; 
    } 

    @Override 
    public void writeToParcel(Parcel dest, int flags) { 
     Bundle b = new Bundle(); 
     b.putSerializable("map", (HashMap<String, Message[]>)emailsMap); 

     dest.writeBundle(b); 
    } 

    public Map<String, Message[]> getEmailsMap() 
    { 
     return emailsMap; 
    } 
} 

任何人都可以請指出正在做什麼錯？如果有任何問題，請告訴我如何實現這些編碼和解組代碼？

提前感謝。

在你的onSaveInstanceState 方法你試圖做一個包裹出來的com.sun.mail.imap.IMAPMessage一個或多個實例，其中不包括Parcellable接口。你試圖包裝的所有實例都必須實現這個接口。
