As per my comment on Mike Ortiz' answer, I believe his answer is wrong:

getChildAt() only counts the children that are visible on screen. Meanwhile, getLastVisiblePosition returns the index based on the Adapter. So if the lastVisiblePosition is 8 because it's the 9th item in the list and there are only 4 visible items on screen, you're gonna get a crash. Verify it by calling getChildCount() and see. The indices for getChildAt are not the same as the indices for the data set. Check this out: ListView getChildAt returning null for visible children

Here's my solution:

public boolean isScrollable() {
        int last = listView.getChildCount()-1; //last visible listitem view
        if (listView.getChildAt(last).getBottom()>listView.getHeight() || listView.getChildAt(0).getTop()<0) { //either the first visible list item is cutoff or the last is cutoff
                return true;
        }
        else{
            if (listView.getChildCount()==listView.getCount()) { //all visible listitem views are all the items there are (nowhere to scroll)
                return false;
            }
            else{ //no listitem views are cut off but there are other listitem views to scroll to
                return true;
            }
        }
    }
