通过单击通知停止AlarmManager

Question

Good day, I hope that someone will be able to help me! I have AlarmManager and NotificationCompat in my application. I want to stop playing alarm when I just click on notification. Here's my code:

public class MyAlarm extends BroadcastReceiver {

private static final int NOTIFICATION_ID = 101;

@Override
public void onReceive(final Context context, Intent intent) {
    NotificationHelper notificationHelper = new NotificationHelper(context);
    MediaPlayer mediaPlayer = MediaPlayer.create(context, Settings.System.DEFAULT_RINGTONE_URI);
    Uri uri = intent.getData();

    Intent newIntent = new Intent(context, AddNoteActivity.class);
    newIntent.setData(uri);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, newIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder nb = notificationHelper.getChannel1Notification(pendingIntent);

    notificationHelper.getManager().notify(NOTIFICATION_ID, nb.build());

    mediaPlayer.start();
}

NotificationHelper:

public class NotificationHelper extends ContextWrapper {

public static final String chanel1ID = "chanel1ID";
public static final String chanel1Name = "chanel 1";

private NotificationManager notificationManager;

public NotificationHelper(Context base) {
    super(base);
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
        createChannels();
    }
}
@RequiresApi(api = Build.VERSION_CODES.O)
public void createChannels(){
    NotificationChannel channel1 = new NotificationChannel(chanel1ID, chanel1Name, NotificationManager.IMPORTANCE_DEFAULT);
    channel1.enableLights(true);
    channel1.enableVibration(true);
    channel1.setLightColor(R.color.colorPrimary);
    channel1.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);

    getManager().createNotificationChannel(channel1);
}

public NotificationManager getManager() {
    if (notificationManager == null) {
        notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    }

    return notificationManager;
}

public NotificationCompat.Builder getChannel1Notification(PendingIntent intent){

    return new NotificationCompat.Builder(getApplicationContext(), chanel1ID)
            .setContentTitle("asda")
            .setContentIntent(intent)
            .setSmallIcon(R.drawable.ic_notifications_black_24dp)
            .setAutoCancel(true);
}

and setAlarm in 3rd class:

public void setAlarm(long timeInMillis){

    if(Build.VERSION.SDK_INT >= 23){
        mCalendar.set(
                mCalendar.get(Calendar.MONTH),
                mCalendar.get(Calendar.YEAR),
                mCalendar.get(Calendar.DAY_OF_YEAR),
                mCalendar.get(Calendar.HOUR_OF_DAY),
                mCalendar.get(Calendar.MINUTE)
        );
    }

    final AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    Intent intent = new Intent(this, MyAlarm.class);
    intent.setData(currentUri);

    final PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    alarmManager.setExact(AlarmManager.RTC, timeInMillis, pendingIntent);

Hope someone will help me here, because I lost almost all day for find a solution. Thank you for your time!

NotificationCompat.Builder.setContentIntent

Supply a PendingIntent to send when the notification is clicked.

You're using

Intent newIntent = new Intent(context, AddNoteActivity.class);

So, in your AddNoteActivity you need to get the instance of your MediaPlayer and call stop().
