SwipeEvent for Android application

I am making an application to control SwipeView but only the validations left to right and right to left are working. The top-down and bottom-up validations are not working.

Could someone please help me?

  

I'll share a code that does all the validations and met all the expectations I wanted to make in the app , including it also validates a double tap on the screen.

My new code ( filtroGestos.java ):

import android.app.Activity;
import android.view.GestureDetector;  
import android.view.GestureDetector.SimpleOnGestureListener;
import android.view.MotionEvent;

public class filtroGestos extends SimpleOnGestureListener {

public final static int SWIPE_CIMA    = 1;
public final static int SWIPE_BAIXO  = 2;
public final static int SWIPE_ESQUERDA  = 3;
public final static int SWIPE_DIREITA = 4;

public final static int MODE_TRANSPARENT = 0;
public final static int MODE_SOLID       = 1;
public final static int MODE_DYNAMIC     = 2;

private final static int ACTION_FAKE = -13; //um número improvável
private int swipe_Min_Distance = 100;
private int swipe_Max_Distance = 350;
private int swipe_Min_Velocity = 100;

private int mode             = MODE_DYNAMIC;
private boolean running      = true;
private boolean tapIndicator = false;

private Activity context;
private GestureDetector detector;
private SimpleGestureListener listener;

public filtroGestos(Activity context,SimpleGestureListener sgl) {

    this.context = context;
    this.detector = new GestureDetector(context, this);
    this.listener = sgl;
}

public void onTouchEvent(MotionEvent event){

    if(!this.running)
        return;

    boolean result = this.detector.onTouchEvent(event);

    if(this.mode == MODE_SOLID)
        event.setAction(MotionEvent.ACTION_CANCEL);
    else if (this.mode == MODE_DYNAMIC) {

        if(event.getAction() == ACTION_FAKE)
            event.setAction(MotionEvent.ACTION_UP);
        else if (result)
            event.setAction(MotionEvent.ACTION_CANCEL);
        else if(this.tapIndicator){
            event.setAction(MotionEvent.ACTION_DOWN);
            this.tapIndicator = false;
        }

    }
    //Senão não faça nada
}

public void setMode(int m){
    this.mode = m;
}

public int getMode(){
    return this.mode;
}

public void setEnabled(boolean status){
    this.running = status;
}

public void setSwipeMaxDistance(int distance){
    this.swipe_Max_Distance = distance;
}

public void setSwipeMinDistance(int distance){
    this.swipe_Min_Distance = distance;
}

public void setSwipeMinVelocity(int distance){
    this.swipe_Min_Velocity = distance;
}

public int getSwipeMaxDistance(){
    return this.swipe_Max_Distance;
}

public int getSwipeMinDistance(){
    return this.swipe_Min_Distance;
}

public int getSwipeMinVelocity(){
    return this.swipe_Min_Velocity;
}

@Override
public boolean onFling(MotionEvent event1, MotionEvent event2, float velocityX,
                       float velocityY) {

    final float xDistance = Math.abs(event1.getX() - event2.getX());
    final float yDistance = Math.abs(event1.getY() - event2.getY());

    if(xDistance > this.swipe_Max_Distance || yDistance > this.swipe_Max_Distance)
        return false;

    velocityX = Math.abs(velocityX);
    velocityY = Math.abs(velocityY);
    boolean result = false;

    if(velocityX > this.swipe_Min_Velocity && xDistance > this.swipe_Min_Distance){
        if(event1.getX() > event2.getX()) // esquerda para direita
            this.listener.onSwipe(SWIPE_ESQUERDA);
        else
            this.listener.onSwipe(SWIPE_DIREITA);

        result = true;
    }
    else if(velocityY > this.swipe_Min_Velocity && yDistance > this.swipe_Min_Distance){
        if(event1.getY() > event2.getY()) // baixo para cima
            this.listener.onSwipe(SWIPE_CIMA);
        else
            this.listener.onSwipe(SWIPE_BAIXO);

        result = true;
    }

    return result;
}

@Override
public boolean onSingleTapUp(MotionEvent e) {
    this.tapIndicator = true;
    return false;
}

@Override

    this.listener.onDoubleTap();
    return true;

        this.context.dispatchTouchEvent(arg);
    }

    return false;
}

static interface SimpleGestureListener{
    void onSwipe(int direction);
    void onDoubleTap();

}
