Android/Java - Chaining multiple Method calls at the same time? Example provided

Simply put, I have an if statement with multiple different outcomes, but a lot of code in common.
I want to make sure that the following Code is the proper way to do what I'm trying to do
(ex: chaining Method calls, as shown).. is this correct?

SharedPreferences getPrefs =
    PreferenceManager.getDefaultSharedPreferences(getApplicationContext());

final String notifType = getPrefs.getString
    (PREF_NOTIFICATION_TYPE, NOTIFICATION_TYPE_SOUND_AND_VIBRATION);

if (notifType != null && notifType.equals
    (NOTIFICATION_TYPE_SOUND_AND_VIBRATION)) {
        // Call the appropriate Methods, depending on the Preference..
        notificationVibration();
        playNotificationTone();
        showReminderNotification();

} else if (notifType !=null && notifType.equals
    (NOTIFIATION_TYPE_VIBRATION_ONLY)) {
        // Calling alot of the same code, but minus the Sound..
        notificationVibration();
        showReminderNotification();

} else if (notifType !=null && notifType.equals
    (NOTIFIATION_TYPE_SILENT_REMINDER)) {
        // Again re-using common code..
        showReminderNotification(); 
}

public void notificationVibration() {
    // Vibration code here
}

public void playNotificationTone() {
    // Sound code here
}

public void showReminderNotification() {
    // Notification code here
}

SO - is this the correct way to go about this?
Can I chain Method calls (as shown) and have them all fire at the same time?
If not, what is the correct way to efficiently execute this?
Feedback greatly appreciated! Thanks.
