Starting from Oskar's answer (thanks for your contribute) i create a simple example project to manage Slide Button (horizontal and vertical) : https://github.com/rcaboni/AndroidSlideButton

For a screen shot : https://raw.githubusercontent.com/rcaboni/AndroidSlideButton/master/screenshot.jpg

This is the main method :

public boolean onTouchEvent(MotionEvent event) {
    if (!isEnabled()) {
        return false;
    }
    if (orientation == ORIENTATION_HORIZONTAL) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            int x= (int) event.getX();
            int y= (int) event.getY();
            if (thumb.getBounds().contains((int) event.getX(), (int) event.getY())) {
                super.onTouchEvent(event);
            } else
                return false;
        } else if (event.getAction() == MotionEvent.ACTION_UP) {
            if (getProgress() > 70)
                handleSlide();

            setProgress(0);
        } else
            super.onTouchEvent(event);
    }else{
        int i=0;
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    int x= (int) event.getX();
                    int y= (int) event.getY();
                    if (!thumb.getBounds().contains((int) event.getY(), (int) event.getX())) {
                        return false;
                    }
                }
            case MotionEvent.ACTION_MOVE:
                i=getMax() - (int) (getMax() * event.getY() / getHeight());
                setProgress(100 - i);
                onSizeChanged(getWidth(), getHeight(), 0, 0);
                break;
            case MotionEvent.ACTION_UP:
                i=getMax() - (int) (getMax() * event.getY() / getHeight());
                if (i < 30) {
                    handleSlide();
                }
                setProgress(0);
                onSizeChanged(getWidth(), getHeight(), 0, 0);
                break;

            case MotionEvent.ACTION_CANCEL:
                break;
        }
    }
    return true;
}

XML for vertical button :

It's not a real complete widget because is composed from two view (TextView and SlideButton) into a Layout, but it's a easy configurable solution for Slide Button with text inside. I hope this is useful for someone.
