Wywołanie java.lang.RuntimeException: Sporadycznie napotkany obiekt IOException zapisujący obiekt serializowany w systemie Android przekazujący obiekt ArrayList

Question

Chcę przekazać mój obiekt ArrayList do innego działania przy użyciu obiektu DataWrapper, który implementuje Serializable.
Połączyłem się z odpowiedzią podaną tutaj: Pass arraylist of user defined objects to Intent android.
Rozpoczynam kolejną aktywność z MPAndroidChart biblioteki PieChart 's OnChartGestureListener(). W ten sposób zdałem ArrayList obiekt threadList:

mChart.setOnChartGestureListener(new OnChartGestureListener() { 
@Override 
public void onChartSingleTapped(MotionEvent me) { 
    Intent intent = new Intent(MainActivity.this, TextersSmsActivity.class); 
    intent.putExtra("threadList", new DataWrapper(threadList)); 
    MainActivity.this.startActivity(intent); 
} 
//..... 
} 

I wdrożone klasę DataWrapper tak:

public class DataWrapper implements Serializable { 
private static final long serialVersionUID = 100L; 
private ArrayList<OneThread> threadList; 

    public DataWrapper(ArrayList<OneThread> threadList) { 
     this.threadList = threadList; 
    } 

    public ArrayList<OneThread> getThreadList() { 
     return threadList; 
    } 
} 

i uzyskiwanie błąd Parcelable encountered IOException writing serializable object. Oto moja Logcat:

Śledziłem odpowiedź (przekazać przedmiotów list tablica) w linku powyżej, ale otrzymuję błąd, co jest przyczyną błędu i jak go usunąć?

Answer 1

Twoja klasa OneThread również powinna implementować Serializable. Wszystkie podklasy i wewnętrzne podklasy muszą implementować Serializable.
