J'essaie de passer un objet d'une activité à une autre, mon objet est une classe personnalisée de java et implémente déjà sérialisable. le principal problème, je ne peux pas trouver un moyen approprié pour y parvenir.Comment transférer un objet de l'activité à l'activité en utilisant Serializable?

toutes les réponses d'autres questions sur stackoverflow de type similaire, ne semble pas résoudre mon problème.

duplicata possible de [Comment envoyer un objet d'une activité Android à une autre en utilisant Intents?] (http://stackoverflow.com/questions/2139134/how-to-send-an-object -de-un-android-activity-to-another-using-intents) –

J'ai vu beaucoup de questions à ce sujet, mais je ne connais pas cet exemple de méthode sérialisable, ça ne semble pas fonctionner pour moi, mais ça plante mon activité. –

Dans la première activité à passer:

Intent intent = new Intent(First.this, Second.class); 
intent.putExtra("ObjectToPass", myObject); 
startActivity(intent);

Dans l'activité Deuxième pour récupérer l'objet:

MyObject myObject = (MyObject) getIntent().getSerializableExtra("ObjectToPass");

Cela suppose queLa classeimplémente déjà Serializable.

cette méthode ne fonctionne pas, elle bloque plutôt mon activité. –

C'est la bonne façon de le faire. Quelle est l'erreur Logcat? Postez ça. –

@BadComputer S'il y a une possibilité que l'activité de réception soit démarrée sans passer l'objet, assurez-vous de tester null avant d'essayer de l'utiliser. –

Je pense que vous pouvez appeler intent.putExtra("key", obj) sur votre intention lorsque obj est votre objet et entrez la clé dans laquelle vous souhaitez stocker l'objet. Dans l'activité démarrée, vous pouvez appeler getIntent().getSerializableExtra("key") pour récupérer votre objet. Voir this link.
