Est-il possible d'ajouter un badge à l'icône d'une application Android?

Malheureusement, Android ne pas autoriser la modification de l'icône de l'application, car il est scellé dans le APK une fois que le programme est compilé. Il n'existe aucun moyen de modifier par programmation à un "drawable'.

Vous pouvez atteindre votre objectif à l'aide d'un widget au lieu d'une icône. Les Widgets sont hautement personnalisables et peuvent faire ce que vous voulez.

Il y a une brève discussion à propos de la différence entre l'iPhone icône de notification et à l'aide de widgets ici:

http://www.cnet.com/8301-19736_1-10278814-251.html

Comme vous pouvez le remarquer, il n'y a pratiquement pas de différence entre l'utilisation d'un widget ou une icône, car ils peuvent être de la même taille et le même aspect.

ShortcutBadger bibliothèque rend possible et fonctionne avec LG, Sony, Samsung, HTC et d'autres Lanceurs personnalisés.

Il a même un moyen d'affichage de compteur dans le plus Pur Android appareils de bureau.

Mise à jour du compteur dans l'icône de l'application est aussi simple que d'appeler:

int badgeCount = 1;
ShortcutBadger.setBadge(getApplicationContext(), badgeCount);

Il comprend une démo de l'application qui vous permet de tester son comportement.

OU

vous pouvez également essayer d'activité-alias de le faire, mais dans ce vous avez besoin pour créer des icônes différentes avec insigne de valeurs ,il sera parfait dans le cas où vous avez besoin de basculer entre les 2 différentes icônes d'Application (besoin de créer différentes activités-alias pour l'affichage de l'icône différente je.e plus d'icônes = plus d'activité-alias).
