使用下面的命令发布通知。
Uri defaultUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Uri alarmSound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE
+ "://" + context.getPackageName() + "/" + R.raw.bells);
Notification notification = new NotificationCompat.Builder(context, App.CHANNEL_ID)
.setContentTitle(description)
.setContentText(notificationMessageArray[randomIndex])
.setSmallIcon(R.drawable.ic_buddha)
.setDefaults(Notification.DEFAULT_VIBRATE)
.setSound((PrefManager.getPrefManager(context).getNotificationSound().equals("Bell") ? alarmSound : defaultUri), AudioManager.STREAM_NOTIFICATION)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_REMINDER)
.build();
Log.e(TAG, "Posting Notification " + description);
notificationManager.notify(new Random().nextInt() * 100, notification);
在创建频道之前,我正在删除具有频道id的旧频道。
我不知道我在这个代码中哪里出错了
如果我从频道和通知中删除设置声音的代码,则默认声音不播放,但其他通知有声音!。我尝试将importent
HIGH
更改为DEFAULT
,但结果仍然相同。设置声音只是设置铃声。只需添加setonlylertonce(true),代码如下所示:
Notification notification = new NotificationCompat.Builder(context, App.CHANNEL_ID)
.setContentTitle(description)
.setContentText(notificationMessageArray[randomIndex])
.setSmallIcon(R.drawable.ic_buddha)
.setDefaults(Notification.DEFAULT_VIBRATE)
.setSound((PrefManager.getPrefManager(context).getNotificationSound().equals("Bell") ? alarmSound : defaultUri), AudioManager.STREAM_NOTIFICATION)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_REMINDER)
.setOnlyAlertOnce(true)
.build();
