Prevent google map from triggering swipe-to-refresh

I have the current layout (obviously simplified here):

<SwipeRefreshLayout>

  <MapFragment/>

  <ListView/>

</SwipeRefreshLayout>

To solve the issue of having the downward swipe triggering the refresh, I tried doing the following:

  mMap.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() {
        @Override
        public void onCameraChange(CameraPosition cameraPosition) {
            mSwipeRefreshLayout.setEnabled(false);
        }
    });

And then enabling back in the listview:

    listView.setOnScrollListener(new AbsListView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
             mSwipeRefreshLayout.setEnabled(true);
        }
        // Prevents the downward swipe from triggering refresh unless the 
        @Override
        public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
            int topRowVerticalPosition = (listView == null || listView.getChildCount() == 0) ? 0 : listView.getChildAt(0).getTop();
            mSwipeRefreshLayout.setEnabled((topRowVerticalPosition >= 0));
        }
    });

However, for some reason, this only works if I swipe two times on the listview, which breaks user experience.

I do not want the move the map fragment out of the SwipeRefreshLayout view because that would move the animation out of place.

Can someone point me on the right direction please?

I found the solution to this problem. Extended SwipeRefreshLayout and overrode onInterceptTouchEvent.

public class OverviewSwipeRefreshLayout extends SwipeRefreshLayout {

    public OverviewSwipeRefreshLayout(Context context) {
        super(context);
    }

    public OverviewSwipeRefreshLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        final int action = ev.getAction();
        switch (action) {
            case MotionEvent.ACTION_DOWN:
                super.onTouchEvent(ev);
                break;
            case MotionEvent.ACTION_MOVE:
                return false;
            case MotionEvent.ACTION_CANCEL:
                super.onTouchEvent(ev);
                break;
            case MotionEvent.ACTION_UP:
                return false;
            default:
                break;
        }

        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        super.onTouchEvent(ev);
        return true;
    }
}
