Question

我正在尝试在状态栏通知上进行自定义声音播放。 .mp3 文件位于 res / raw / 中。但是当我通知用户声音没有播放时。我已经尝试使用MediaPlayer，它可以工作，但我不想让它与MediaPlayer一起玩。

这是我的方法：

public void showNotification()
{
        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

        int icon = R.drawable.feedback;        // icon from resources
        CharSequence tickerText = mContext.getString(R.string.statusbar_notification); // ticker-text
        long when = System.currentTimeMillis();         // notification time
        Context context = getApplicationContext();      // application Context
        CharSequence contentTitle = mContext.getString(R.string.statusbar_notification);  // message title
        CharSequence contentText = mContext.getString(R.string.statusbar_notificatione_detailed);      // message text

        Intent notificationIntent = new Intent(mContext, Main.class);
        PendingIntent contentIntent = PendingIntent.getActivity(mContext, 0, notificationIntent, 0);

        // the next two lines initialize the Notification, using the configurations above
        Notification notification = new Notification(icon, tickerText, when);

        //notification.defaults |= Notification.DEFAULT_SOUND;
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notification.sound = Uri.parse("android.resource://" + getPackageName() + "/R.raw.notificationsound");

        notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        mNotificationManager.notify(1, notification);
}

感谢。

来自ContentResolver的文档：

Uri应该是以下格式之一： android.resource：//程序包/ ID_NUMBER

您正在传递字符串“R.raw.notificationsound”，这意味着什么。相反，试试这个：

notification.sound = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notificationsound );

自定义通知声音无法播放
