You can't directly call methods when you click action buttons.

You have to use PendingIntent with BroadcastReceiver or Service to perform this. Here is an example of PendingIntent with BroadcastReciever.

First lets build a Notification

public static void createNotif(Context context){

    ...
    //This is the intent of PendingIntent
    Intent intentAction = new Intent(context,ActionReceiver.class);

    //This is optional if you have more than one buttons and want to differentiate between two
    intentAction.putExtra("action","actionName");

    pIntentlogin = PendingIntent.getBroadcast(context,1,intentAction,PendingIntent.FLAG_UPDATE_CURRENT);
    drivingNotifBldr = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.steeringwheel)
            .setContentTitle("NoTextZone")
            .setContentText("Driving mode it ON!")
            //Using this action button I would like to call logTest
            .addAction(R.drawable.smallmanwalking, "Turn OFF driving mode", pIntentlogin)
            .setOngoing(true);
    ...

}

Now the receiver which will receive this Intent

public class ActionReceiver extends BroadcastReceiver {

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

        //Toast.makeText(context,"recieved",Toast.LENGTH_SHORT).show();

        String action=intent.getStringExtra("action");
        if(action.equals("action1")){
            performAction1();
        }
        else if(action.equals("action2")){
            performAction2();

        }
        //This is used to close the notification tray
        Intent it = new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
        context.sendBroadcast(it);
    }

    public void performAction1(){

    }

    public void performAction2(){

    }

}

Declare Broadcast Receiver in Manifest

<receiver android:name=".ActionReceiver" />

Hope it helps.
