Problème code Android

Bonjour,

J'ai un petit problème pour finir mon projet Android Studio. Je suis étudiante en DUT R&T et nous avons comme projet de créer une liste de contacts où nous pouvons : ajouter, supprimer, modifier et appeler un contact sélectionné ou annuler la sélection. Le bouton "annuler" fonctionne. Le bouton "ok" fonctionne également.

Mais le bouton "modifier", il le modifie dans le toast mais pas dans l'affichage et je comprend pas pourquoi... Les boutons "supprimer", "appeler" et "ajouter" ne marchent pas . J'ai donc enlevé du code ceux-là et je cherche toujours comment faire...

Je vous affiche les codes, si vous pouviez m'aider, c'est à rendre pour demain...

La classe Contact :
