Problème : ViewSwitcher + ImageButton
Bonjour,
j'essaye de créer un menu de jeu et dans ce menu, j'ai une vue qui permet de sélectionner la campagne (comme suit) :
http://img853.imageshack.us/img853/6...nselection.png
Pour cela, j'ai eu l'idée d'utiliser un ViewSwitcher pour ne pas avoir une Activity par campagne.
Le problème, c'est que le switcher me permet de faire défiler des ImageButton qui sont censés permettre de sélectionner la campagne et d'afficher un aperçu (image) de la campagne (d'où l'ImageButton) et que quand je run l'appli, ça me renvoit l'erreur :

Merci ;)
