Android 通知播放音一次
Android Notification play sound once
我正在使用此代码向用户发送通知:
NotificationManager notificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
Group group = new Group(Integer.parseInt(serverNotification.getGroupID()), serverNotification.getGroupTitle());
Intent intent = new Intent(this, MainActivity.class);
if (serverNotification.getType() != Notification.NotificationType.VIDEO_PROCESS_COMPLETED) {
intent.putExtra(MainActivity.EXTRA_MODE, MainActivity.MODE_GROUP_VIDEOS);
intent.putExtra(MainActivity.EXTRA_GROUP, group);
if (serverNotification.getVideoID() != null && serverNotification.getVideoID().length() != 0) {
intent.putExtra(MainActivity.EXTRA_VIDEO_ID, serverNotification.getVideoID());
}
}
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
android.app.Notification.Builder builder = new android.app.Notification.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher))
.setWhen(System.currentTimeMillis())
.setContentText(serverNotification.getMessage())
.setTicker(serverNotification.getMessage())
.setAutoCancel(true)
.setContentTitle("MyApp");
builder.setContentIntent(contentIntent);
if (Build.VERSION.SDK_INT >= 16) {
notificationManager.notify(GROUP_NOTIFICATION_ID++, builder.build());
} else {
notificationManager.notify(GROUP_NOTIFICATION_ID++, builder.getNotification());
}
try {
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
r.play();
} catch (Exception e) {
e.printStackTrace();
}
问题是,当我收到多个通知(连续 3+ 个)时,它会播放多次声音,有什么方法可以只播放一次声音吗?
您不需要自己播放声音 - 试试:
builder.setSound(
RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
或者更好,因为您使用的是默认声音:
builder.setDefaults(Notification.DEFAULT_SOUND);
顺便说一句 - 避免在代码中使用显式数字(和文字),使用常量:
Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN
而不是 Build.VERSION.SDK_INT < 16
。它确实提高了代码的可读性。
