Paramètre fonction non pris en compte.
Bonsoir,
Je me lance depuis peu dans le développement android ( et le java :D ).
Dans le cadre de mon application j'ai décidé d'utiliser un tabhost.
Je recontre un problème dans l'un des deux onglets.
En effet, cet onglet est un formulaire tout bête permettant d'envoyer 3 variables pour un calcul.
Auparavant je transmettais ca à une nouvelle activity et celà fonctionnais sans problème.
Afin d'améliorer le "confort" de mon application j'ai décidé de simplement changer de "view" tout en éxécutant une fonction "calculate" afin d'effectuer le traitement utile à ma sortie ( TextView ), ici celà coince et Logcat me balance l'exception suivante :
