android.la base de données.CursorIndexOutOfBoundsException

Le code d'accès aux données dans mon application Android soulève une exception.

Voici le code qui provoque l'exception:

String getPost = "SELECT * FROM " + TABLE_POST + ";";
Cursor result = getReadableDatabase().rawQuery(getPost, null);
List posts = new ArrayList();{
Log.d("count", result.getCount() + " post rows");
while (result != null && result.moveToNext());
    Post post = new Post();
    post.setPostId(result.getInt(0));
    posts.add(post);
    ....
}

L'exception soulevée est:

android.database.CursorIndexOutOfBoundsException: Index 2 requested, with a size of 2 exception

Le journal méthode produit le résultat 2 post rows.

Quel est le problème ici?

Edit:
J'ai ajouté le plein de trace de pile, de sorte que ceux qui souhaitent vue, il peut le faire.

  • Merci de montrer toute la trace de la pile plutôt que de simplement le type et le message.
  • Vous n'avez pas de nous montrer tout le code. Quelque part que vous appelez result.getInt(2) ou result.getString(2) ou autrement, en utilisant un indice de 2.
  • J'ai ajouté la trace de la pile, mais je pense que le problème est résolu.
