I Programmer une application de quiz commençant par l'activité principale (activité du quiz). J'ai déjà mis en place que si le highscore est supérieur à 10, un ImageView sera affiché en permanence dans Menu2 Activity. Cela fonctionne très bien aussi au redémarrage de l'application, le seul problème est que si l'utilisateur atteint un highscore de par exemple 11 l'image ne sera pas immédiatement affichée, il sera montré si l'utilisateur frappe directement après par exemple un score de 3 sera montré en permanence. Comment puis-je configurer que l'image sera affichée lorsque le highscore est atteint?Erreur dans les préférences partagées, ImageView disparaît
