私はグリッチがどこにあるのかわからず、API 1以降のようにリンクリストが問題だとは思いませんが、Android API 18では発生しませんが、どこに問題があるのか わかりませんか?
保存:
FileOutputStream fos = null;
try {
fos = openFileOutput("shelf.obj", Context.MODE_PRIVATE);
ObjectOutputStream out = new ObjectOutputStream(fos);
out.writeObject(listOfShelfs);
out.close();
fos.close();
} catch (FileNotFoundException e) {
//catch
} catch (IOException e) {
//catch
}
保存するオブジェクト:
private static HashMap<String, MessageShelf> listOfShelfs = new HashMap<String, MessageShelf>();
メッセージシェルフ:
public class MessageShelf implements Serializable{
private static final long serialVersionUID = 1L;
public Friend correspodent;
Calendar lastSeen;
Calendar lastSend;
boolean secure;
Queue<MessageList> historyMessagesLists=new LinkedList<MessageList>();
public String lastMessageBody = "";
public Calendar lastDate;}
