Bonjour à tous,

Je suis en train de bosser sur un petit projet d'initiation en combinant différents exemples trouvés sur ce site et je butte depuis plusieurs jours sur un problème.

Dans ce projet j'utilise un "template eclipse" qui utilise un ViewPager combiné avec un FragmentPagerAdapter et je n'arrive pas a trouver comment je dois faire pour mettre à jour les TextView contenus sur les fragments.

Je souhaiterais mettre à jour ces valeurs toutes les minutes via un 'Runnable'. Quelqu'un aurait-il une piste pour résoudre ce problème ?

Merci,
Sam-
