Question

我正在尝试使用notificatoin和rington来发出警报。

如何正确完成？

我的工作：从我的活动中我通过使用alarmmanager调用BroadcastReceiver，而不是在BroadcastReceiver中使用NotificationCompat.Builder进行通知，之后我调用该服务。

如何通过向外滑动或双击通知来取消铃声？

{

private Intent notificationIntent;

@Override
public void onReceive(Context context, Intent intent) {

    String title = intent.getStringExtra("myTitle");
    notificationIntent = new Intent();
    checkIntent(title, context);

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
            .setContentIntent(pendingIntent)
            .setSmallIcon(R.drawable.dumbbell)
            .setContentTitle("Tracker")
            .setContentText(title)
            .setAutoCancel(true);

    notificationManager.notify(1, builder.build());

    Intent ringtoneIntent = new Intent(context, AlarmService.class);
    context.startService(ringtoneIntent);
}

private void checkIntent(String title, Context context) {
    switch (title){
        case "Weight":
            notificationIntent = new Intent(context, WeightActivity.class);
            break;
        case "Measure":
            notificationIntent = new Intent(context, measurActivity.class);
            break;
        case "Pr":
            notificationIntent = new Intent(context, PrsActivity.class);
            break;
        case "Macros":
            notificationIntent = new Intent(context, DietActivity.class);
            break;
    }
}

公共类AlarmService扩展了服务{

private MediaPlayer alarmSong;

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    alarmSong = MediaPlayer.create(this, R.raw.willy_william_voodoo);
    alarmSong.start();
    System.out.println("RING RING");

    return START_NOT_STICKY;
}

@Override
public void onDestroy() {
    super.onDestroy();
}

@Override
public void onTaskRemoved(Intent rootIntent) {
    super.onTaskRemoved(rootIntent);
    System.out.println("removed");
}

}

据我了解，您想停止服务AKA停止铃声。用户可以解除所有通知，或者如果您将通知设置为自动取消（您拥有），则在用户选择通知后也会将其删除。

您还可以在NotificationManager上为特定通知ID调用cancel（）。 cancelAll（）方法调用将删除您先前发出的所有通知。您还可以为服务实现新的PendingIntent以自行停止。

添加到OnStartCommand()

notificationManager.cancel(NOTIFCATION_ID);
        stopSelf();

然后添加新的Intent

Intent stopSelf = new Intent(this, AlarmService.class);
    stopSelf.setAction(this.ACTION_STOP_SERVICE);
    PendingIntent pStopSelf = PendingIntent.getService(this, 0, stopSelf,PendingIntent.FLAG_CANCEL_CURRENT);
    notificationManager.notify(NOTIFCATION_ID, builder.build());

要停止实际的音乐播放，请在您的服务中调用alarmSong.stop（）onDestroy()！

希望它有所帮助！
