Scroll even if the seekbar is touched

Question

I am using a seekbar in a linearlayout in a ScroolView in a NavigationDrawer

NavigationDrawer > ScrollView > LinearLayout > SeekBar + other stuff

When I touch the seekbar I am unable to scroll up and down and I'd like to.

Here my function which allow me to slide the seekbar instead of slide the navigation drawer

private View onCritereView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View mView = inflater.inflate(R.layout.fragment_critere, container, false);
    LinearLayout mLinearLayout = (LinearLayout) mView.findViewById(R.id.critere_linearlayout);

    int i;
    for (i = 0; i < mTitles.length; i++) {
        View mViewElement = inflater.inflate(R.layout.item_critere, null);
        ((TextView) mViewElement.findViewById(R.id.critere_title)).setText(mTitles[i]);
        SeekBar mSeekBar = (SeekBar) mViewElement.findViewById(R.id.critere_qualifier);
        mSeekBar.setOnTouchListener(new ListView.OnTouchListener()
        {
            @Override
            public boolean onTouch(View v, MotionEvent event)
            {
                int action = event.getAction();
                switch (action)
                {
                    case MotionEvent.ACTION_DOWN:
                        // Disallow Drawer to intercept touch events.
                        v.getParent().requestDisallowInterceptTouchEvent(true);
                        break;

                    case MotionEvent.ACTION_UP:
                        // Allow Drawer to intercept touch events.
                        v.getParent().requestDisallowInterceptTouchEvent(false);
                        break;
                }

                // Handle seekbar touch events.
                v.onTouchEvent(event);
                return true;
            }
        });
        mLinearLayout.addView(mViewElement);
    }
    return mView;
}

Now what I need is:

If you touch the seekbar and if you slide hozizontaly use seekbar.

else if you touch the seekbar and if you slide verticaly use scrollview

How can I do that ?

Thanks in advance :)
