我可以为 Firebase 通知设置自定义铃声和振动模式吗?

Can I set a custom ringtone and vibration pattern for a firebase notification?

最近我开始编写我的第一个 android 项目,其中包括 Firebase 云消息传递。我使用 Android SDK 21 (Android 5).

我的意图是让用户选择播放哪种铃声以及设备是否振动。为此,我创建了一个助手 class SettingsHandler,它可以像这样访问用户设置:

public synchronized static Uri getRingtoneUri(Context context) {
    Sharedpreferences prefs = context.getSharedPreferences("table_name", Context.MODE_PRIVATE);
    return Uri.parse(prefs.getString("ringtone_key"), RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION).toString());
}

public synchronized static boolean shouldVibrateOnPush(Context context) {
    SharedPreferences prefs = context.getSharedPreferences("table_name", Context.MODE_PRIVATE);
    return prefs.getBoolean("vibration_flag", true);
}

因此,当我收到来自 Firebase 的通知时,我想设置用户可以使用上述方法设置的声音和振动模式。

为了得到这个,我重写了 MyFirebaseMessagingService 中的 onMessageReceived 方法,它扩展了 - 谁期望这个 - FirebaseMessagingService:

public void onMessageReceived(RemoteMessage msg) {
    super.onMessageReceived(msg);
    if (msg.getNotification() != null) {
        Intent activityIntent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent contentIntent = PendingIntent.getActivity(this, REQUEST_CODE, activityIntent, PendingIntent.FLAG_ONE_SHOT);

        Notification note = new NotificationCompat.Builder(this, "channel_id")
                .setSmallIcon(R.mipmap.icon)
                .setContentTitle(msg.getNotification().getTitle())
                .setContentText(msg.getNotification().getBody())
                .setPriority(NotificationCompat.PRIORITY_HIGH)
                .setCategory(NotificationCompat.CATEGORY_MESSAGE)
                .setAutoCancel(true)
                .setContentIntent(contentIntent)
                .setSound(SettingsHandler.getRingtoneUri(this))
                .setVibrate(SettingsHandler.shouldVibrateOnPush ? new long[] {500, 500, 500, 500, 500} : new long[] {0, 0, 0, 0, 0})
                .build();

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            //create notification channels
        }
        NotificationManagerCompat manager = NotificationManagerCompat.from(this);
        manager.notify(1, note);
    }
}

但是当我发送通知时,总是播放默认声音,所以我开始问自己,我的思维方式是否有错误。任何方式如何正确地做到这一点?提前致谢。

试试这个:
您可以使用以下代码选择铃声:

selsound_button.setOnClickListener(new OnClickListener()
    {   
        public void onClick(View arg0)
        {
            Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "Select ringtone for notifications:");
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, currentUri);
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE,RingtoneManager.TYPE_NOTIFICATION);
    startActivityForResult( intent, 999);  
        }
    }); 

然后您需要在 onActivityResult 方法中处理 currentUri 并将其存储在 sharedPreferences 中以备将来使用。

这里是实际工作:

 @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 999){
            if (data != null) {
                currentUri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
            }
            if (Settings.System.canWrite(this)){
                RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_NOTIFICATION, currentUri);
            }else {
                Intent settings = new Intent("android.settings.action.MANAGE_WRITE_SETTINGS");
                startActivityForResult(settings, 124);
            }
        }
        if (requestCode == 124){
            if (resultCode == Activity.RESULT_OK){
                RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_NOTIFICATION, currentUri);
            }
        }
    }

现在从存储的 sharedPreferences 获取 uri 并在通知中使用:

 notification.setSound(currentUri);
        notification.setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 }));

注意:您需要WRITE_SETTINGS权限才能执行此任务。

创建Resource文件夹(目录res)命名为raw并将文件(声音文件名.mp3)放入其中,比使用以下代码自定义声音

Notification note;
.....
......
note.sound = Uri.parse("android.resource://"+context.getPackageName()+"/"+R.raw.filename);//file name you want to play

对于 Oreo 和更高的 SKD 版本,您需要放入通知频道

Uri sounduri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + context.getPackageName() + "/" + R.raw.filename); //file name you want to play

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

        NotificationChannel Channel = new NotificationChannel("CHANNEL_ID","CHANNEL NAME", NotificationManager.IMPORTANCE_DEFAULT)
        AudioAttributes attributes;
        .... 
        ........
        Channel.setSound(sounduri, attributes); //set the sound


        if (notificationManager != null){
            notificationManager.createNotificationChannel(Channel);}
    }

使用 MediaPlayer class 播放通知声音

MediaPlayer sound = MediaPlayer.create(contex, R.raw.filename);
sound.start();
