カスタムクラスの分解可能

Question

私は現在、クラスイベントのArrayListを別のアクティビティに渡そうとしています。次のように、events.eventsはEventクラスのArrayListです。次のように私はそれからデータを取得しています

Intent i = new Intent(ViewEvents.this, UserFeed.class); 
i.putParcelableArrayListExtra("events",events); 
startActivity(i); 

：

Intent i = getIntent(); 
ArrayList<Event> events = i.getParcelableArrayListExtra("events"); 

私の問題は、私がUmarshing未知のタイプのコード32を取得するということですが、私はこの問題を解決するかどうかはあまりわからないですか、なぜ5788をオフセットこれが発生しています。私は下の3つのクラスのすべてのコードを掲載しました。この問題を解決するためにどんな助けもありがとうございます。

Answer 1

Parcelableインタフェースを実装する場合、それはあなたが読み、正確に一致して書き込み、絶対条件です。あなたの場合、これはあなたのEvent(Parcel)コンストラクタとvoid writeToParcel()です。

ただし、writeToParcel()の実装には、コンストラクタが読み取らない2つの書き込みが含まれています。

dest.writeParcelable(this.venue,flags); 
dest.writeParcelable(this.organizer,flags); 

これらを削除するか、一致する読み込みをコンストラクタに追加する必要があります。

venue = in.readParcelable(Venue.class.getClassLoader()); 
organizer = in.readParcelable(Organizer.class.getClassLoader());
