Je tente de créer une application avec plusieurs activités qui surveille différents aspects de l'interaction de l'utilisateur avec le périphérique. L'un des principaux aspects est la saisie de texte à partir d'un clavier personnalisé. J'ai regardé plusieurs exemples différents en ligne, mais aucun ne semble fonctionner correctement pour moi. Malheureusement, lorsque je tente d'afficher le clavier dans mon activité, il ressemble à ceci: http://puu.sh/jHQFQ/123ddd742b.jpg. Honnêtement, je n'ai aucune idée de pourquoi cela arrive.Clavier virtuel personnalisé Android (Android Studio)
Voici mon clavier: `
