I've solve my issue like this. Call this method

//Here running boolean value
//lv listview

    private void scrollMyListViewToBottom() {
            lv.post(new Runnable() {
                public void run() {
                    if (!running) {

                 // Select the last row so it will scroll into view...
                    iv.setSelection(daily_dairy_2.getCount() - 1);
                    lv.invalidateViews();
                    running = true;
                    }
                }
            });
        }

you can use listview.notifyDatasetChanged() method to refresh your list.

To refresh a Listview, create a ListAdapter and populate it with your items (buttons). Every time you put in it a new set of items, your list gets updated.

Check this reference on ListViews: http://developer.android.com/guide/topics/ui/layout/listview.html
