Basic Scolling Question

Question

Hé les gars, je suis assez nouveau sur la plate-forme android et j'ai une question très simple. Im mettre des boutons comme des dispositions avec des zones de texte, mais im manquer de place. Comment devrais-je permettre à l'utilisateur de faire défiler vers le bas pour voir plus de boutons et d'autres choses. Par exemple, si j'ai 6 boutons, et 3 sont dans le champ de vision, je veux être capable de faire défiler avec mon doigt et être capable de voir ces boutons que je défile.

Merci pour l'aide les gars

Answer 1

Vous pouvez mettre vos commandes (widgets: boutons, étiquettes, etc.) dans un ScrollView. Consultez la documentation de la classe pour plus de détails: http://developer.android.com/reference/android/widget/ScrollView.html

Quelque chose comme:

<ScrollView ..> 
    <TextView .../> 
    <Button .../> 
</ScrollView>
