Cannot pass selfmade serializable object to another activity via intent

Question

I created an object which contains data fields of the types ImageView, boolean and Integer.

public class MemoryCard implements View.OnClickListener, Serializable {

    private ImageView image;
    private int id;
    private int nr;
    private boolean clicked = false;
    private int cardBack;
    private int cardFront;

    public MemoryCard(Context context, int id, int nr, int cardFront)
    {
        this.id = id;
        this.nr = nr;
        this.cardBack = R.drawable.backside;
        this.cardFront = cardFront;
        this.image = new ImageView(context);
        this.image.setImageResource(this.cardBack);
        this.image.setOnClickListener(this);
    }
}

When I start to send an object from MainActivity to SecondActivity then an error occurs and my App stops running.

Intent intent = new Intent(MainActivity.this, SecondActivity.class);

intent.putExtra("object", new MemoryCard(this, 0, 0, R.drawable.myImage));

startActivity(intent);

I think it has something to do with the parameters this and R.drawable.myImage of the MemoryCard constructor but why?

Why not just sending Class object which hold all required data in next Activity to show `ImageView` instead of sending `ImageView` object ? — ρяσѕρєя K, Jul 17 '17 at 15:27
"my App stops running" -- use LogCat to examine the Java stack trace associated with your crash": https://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-how-can-i-solve-this As others have pointed out, most likely, you are crashing on the `ImageView`, as that cannot be serialized. `SecondActivity` has no means of modifying the UI of `MainActivity` directly, which is my guess as to what you are trying to accomplish here. — CommonsWare, Jul 17 '17 at 15:34

Is ImageView serializable? An object if serializable only if it implements Serializable and all its members are serializable.

Is it possible to make ImageView serializiable as well? – Ramón Wilhelm Jul 17 '17 at 15:29
