我正在构建一个 ping 功能,用于通过蓝牙寻找丢失的手机。我需要手机发出声音,即使它设置为静音/无声,就像闹钟通常的工作方式一样。我以为我可以将我的 notification
的 streamtype
放入 AudioManager.STREAM_ALARM
但它不起作用。它仅在电话声音打开时发出声音。我是这样设置的:
NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext());
builder.setSmallIcon(R.drawable.ic_spenwallet)
.setContentTitle("Ping")
.setContentText("Device is trying to find your phone.")
.setAutoCancel(false)
.setSound(sound, STREAM_ALARM)
.setVibrate(vibratePattern)
.addAction(cancelAction);
如果我尝试:
Notification notification = builder.build();
notification.audioStreamType = AudioManager.STREAM_ALARM;
我从 Android Studio 收到一条警告,指出 audioStreamType 已弃用。是这样吗?即使开启了静音模式,还有其他方法可以发出 notificaiton
声音吗? (最好也振动)
我为此目的创建了一个专用的媒体播放器,但我认为不需要这样做。无论如何,我是这样做的:
MediaPlayer mediaPlayer = new MediaPlayer();
final String packageName = getApplicationContext().getPackageName();
Uri sound = Uri.parse("android.resource://" + packageName + "/" + R.raw.ping_sound);
try {
mediaPlayer.setDataSource(this, sound);
} catch (IOException e) {
e.printStackTrace();
}
final AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) {
mediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
mediaPlayer.setLooping(false);
try {
mediaPlayer.prepare();
} catch (IOException e) {
e.printStackTrace();
}
mediaPlayer.start();
}
最佳答案
使用 builder.setSound(alarmSound, AudioManager.STREAM_AUDIO)
正是我让闹钟继续运行所需要的!也许您的问题与您正在使用的 R.raw.ping_sound
声音样本有关。在尝试了一堆可怕的实现之后,我在网上找到了警报通知(这是我找到 Settings.System.DEFAULT_RINGTONE_URI
的地方),我遵循了 official notification documentation然后使用 NotificationCompat.Builder定制文档。
这是我的工作警报通知:
private void showNotification(){
// Setup Intent for when Notification clicked
Intent intent = new Intent(mContext, MedsActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); // See https://developer.android.com/training/notify-user/navigation for better navigation
PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, intent, 0);
// Setup Ringtone & Vibrate
Uri alarmSound = Settings.System.DEFAULT_RINGTONE_URI;
long[] vibratePattern = { 0, 100, 200, 300 };
// Setup Notification
String channelID = mContext.getResources().getString(R.string.channel_id_alarms);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mContext, channelID)
.setContentText(notificationMessage)
.setContentTitle(notificationTitle)
.setSmallIcon(R.mipmap.ic_launcher_round)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setCategory(NotificationCompat.CATEGORY_ALARM)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setContentIntent(pendingIntent)
.setSound(alarmSound, AudioManager.STREAM_ALARM)
.setOnlyAlertOnce(true)
.setVibrate(vibratePattern)
.setAutoCancel(true);
// Send Notification
NotificationManager manager = (NotificationManager) mContext.getSystemService(NOTIFICATION_SERVICE);
manager.notify(NOTIFICATION_ID, mBuilder.build());
}
