Démarrage d’une Activity grâce aux Intents
Salut à tous
je veux activer un bouton qui est affiché dans un AlertDialog,pour démarrer une autre activité.
j'ai trouvé ça :
Code:
1
2
| Intent intent = new Intent(HelloItemizedOverlay.this, CLASSE_DESTINATION.class);
startActivity(intent); |
il faut que ma classe doit heriter de Activity pour que startActivity() soit activer.
hors ma classe herite HelloItemizedOverlay herite de ItemizedOverlay.
voici la classe :
Code:
1
2
