android.view.ViewGroup$LayoutParams cannot be cast to longest.game.FlowLayout$LayoutParams
Bonjour,
J'ai tenté d'implémenter FlowLayout à mon application Android grâce à ce que j'ai trouvé ici : http://nishantvnair.wordpress.com/20...ut-in-android/
Malheureusement, je reçois l'erreur "android.view.ViewGroup$LayoutParams cannot be cast to longest.game.FlowLayout$LayoutParams"...
Mais je ne comprends pas trop ce que cela veut dire et je ne vois pas comment m'en débarrasser :/
Voilà mon fichier main.xml :

Une idée ?
