java.lang.RuntimeException: Parcelable ha rilevato IOException che scrive oggetto serializzabile in Android passando l'oggetto ArrayList

Question

Voglio passare il mio oggetto ArrayList a un'altra attività, utilizzando un DataWrapper che implementa Serializable.
Ho seguito la risposta fornita qui: Pass arraylist of user defined objects to Intent android.
Sto avviando un'altra attività da MPAndroidChart libreria PieChart's OnChartGestureListener(). Ecco come ho passato il mio oggetto ArrayList 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); 
} 
//..... 
} 

ho implementato la classe DataWrapper in questo modo:

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; 
    } 
} 

E ottenere l'errore Parcelable encountered IOException writing serializable object. Ecco il mio Logcat:

Ho seguito la risposta (per passare gli oggetti lista di array) nel link qui sopra, ma ottenendo l'errore, che cosa sta causando l'errore e come rimuoverlo?

Answer 1

La classe OneThread deve anche implementare Serializable. Tutte le sottoclassi e le sottoclassi interne devono implementare Serializable.
