最近,我开始编码我的第一个包含Firebase Cloud Messaging的android项目。我使用的是Android SDK 21(Android 5)。
我的目的是让用户选择播放哪个铃声以及设备是否振动。为此,我创建了一个帮助器类SettingsHandler
,该类可以访问用户设置,如下所示:
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,当我从Firebase收到通知时,我想设置用户可以使用上述方法设置的声音和振动模式。
要获取此信息,我会覆盖onMessageReceived
中扩展的MyFirebaseMessagingService
方法-谁曾期望这样做-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,始终会播放默认声音,所以我开始问自己,我的思维方式是否有误。任何方法如何正确执行?谢谢。

尝试使用此方法:
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。
实际工作在这里:
@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中获取uri,并在通知中用作:
notification.setSound(currentUri);
notification.setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 }));
注意:您需要具有WRITE_SETTINGS权限才能执行此任务。

创建资源文件夹(目录 res ),将其命名为 raw ,然后将文件(声音文件名为.mp3)放入其中,然后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和更高版本的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);}
}
OR 使用MediaPlayer类播放声音以进行通知
MediaPlayer sound = MediaPlayer.create(contex, R.raw.filename);
sound.start();
