Adapter XML au résultat de requête

**Jordan62** · 05/06/2014, 22h17

Bonsoir,

J'ai sur mon application, une requête qui permet de retourner tous les lieux dans la base de données, mais j'aimerais ajouter a chaque lieux retourner un bouton supprimer le lieux (donc il serait affecter au lieux précis)
Comment adapter le nombre de bouton supprimer aux nombre de lieux retourner ?
Mais j'en ai aucune idée de comment je pourrais faire...

Merci de votre aide

Ps : je debute

Par exemple, tu peux utiliser une ListView pour afficher les lieux et considérer qu'un clic sur chaque item déclanche sa suppression coté serveur.

Merci j'ai essayé mais en vain,

A cause du extends Fragment cela pose un soucis....

J'ai mis en police plus grande , les lignes qui posent porblemes avec fragment.
