Question

I have a listView which has its content as random generated numbers. If one item in the listView is scrolled out of the screen and then scrolled back in, the random generated number is changed (it generates a new number).

Is there any way I can prevent this from happening?

A example code is here

Just try this code for listview implement listener and/or your getview() method calling every time on scroll up and/or down,

mListView.setOnScrollListener(new OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            // write down your code here
            // i think notifyDataSetChanged() this method calling whatever u require.
        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem, 
                int visibleItemCount, int totalItemCount) {
            // write down your code here
        }
    }); // mListView.setOnScrollListener close
