bonjour,

Je souhaite modifier dynamiquement le contenu d'un spinner en fonction d'un autre spinner. Apparement il faut passer par un ArrayAdapter. je me suis inspiré de http://developer.android.com/guide/t...s/spinner.html
Je n'ai pas d'erreur de compilation, mais à l'éxécution j'ai une erreur:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part
