you have to set a TouchListener for your drawer layout. eg/

gestureDetector = new GestureDetector(this, new CustomGestureListener());

    mDrawerLayout.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            if (gestureDetector.onTouchEvent(event)) {
                return true;
            }
            return false;
        }
    });
