Je crée un jeu pour Android, j'ai donc décidé de créer un bouton muet qui mettrait la musique en pause. J'ai ajouté le code suivantCréé un bouton de sourdine simple pour mon jeu Android mais il bloque l'application?
for (int i = 0; i < len; i++) {
TouchEvent event = touchEvents.get(i);
if (event.type == TouchEvent.TOUCH_UP) {
if (inBounds(event, 4, 3, 80, 35)) {
if (AndroidMusic.mediaPlayer.isPlaying() == true) {
AndroidMusic.mediaPlayer.setVolume(0.0f,0.0f);
}
}
}
}
Ainsi, lorsque vous touchez entre 4, 3, 80, 35 (le bouton mute) il vérifier si le musis joue et si elle est elle régler le volume à 0.0f . J'ai aussi essayé avec:
AndroidMusic.mediaPlayer.pause();
, mais il ne fonctionne pas non plus. Quand j'efface cette partie de ce code, tout fonctionne parfaitement, mais quand je les place à nouveau, le menu se charge mais au moment où vous touchez n'importe où (même le bouton Lecture, ou un espace vide) il s'arrête puis se bloque .

HalR, j'ai essayé votre code et qui a fait le bouton "mute" pause la musique et ne pas planter l'application, mais il se bloque toujours quand j'appuie sur le bouton "play".
S'il vous plaît donner le LogCat. Cela aide à connaître l'erreur exacte. –
