I am having two listviews in parallel on single screen. Both are having their own scroll listener.

What I want to do is scroll the first listview, then the second listview should also scroll and vice versa.

Is this possible ?

Suppose your ListViews are mListView1 and mListView2, then do something like this - 

  mListView1.setOnScrollListener(new OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {}                   

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {

            // Smooth scroll mListView2 according to mListView1.
            mListView2.smoothScrollToPosition(firstVisibleItem);
        }

        @Override
        private void isScrollCompleted() {}
    });

  • But my both listviews having header. So in case when header is half visible for first listview, how to scroll another listview exactly at same place. – Bunny Aug 01 '15 at 09:01
  • And if i use your without having header on listview, what if i scroll the first listview such that only half of any child is visible on top ? – Bunny Aug 01 '15 at 09:13
