Android - ListView to load more items when reached end

I have successfully implemented a listView where each row is an object I've created. I have an interface which reads some objects and returns an array of them, which I pass to the adapter constructor. What I want to do is, since the list may be very long, My interface allows to read each time some more items (page 0, page 1...) so I Want, when the user reaches the last row of the list, load the next page and insert it to the listView. What is the proper way of doing so? I actually want the "reach end of list" trigger a callback where I can request for more pages and load them to the list. A bit OT to my main question, But I dont mind using a baseAdapter, both would work, I just dont know what's better for the task.


You can add a footer on the listView which will have a button named LoadMore. Here is a complete tutorial ListView with Load More Button Or you can implement onscrolllistener() and add this listener to your ListView

public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
    this.currentFirstVisibleItem = firstVisibleItem;
    this.currentVisibleItemCount = visibleItemCount;

public void onScrollStateChanged(AbsListView view, int scrollState) {
    this.currentScrollState = scrollState;

private void isScrollCompleted() {
    if (this.currentVisibleItemCount > 0 && this.currentScrollState == SCROLL_STATE_IDLE) {
        /*** In this way I detect if there's been a scroll which has completed ***/
        /*** do the work for load more date! ***/
             isLoading = true;

Hope it will help

This might be a very stupid question, but is there a reason why url.parse would return undefined in this case, if I were to simply pass in a URL string, like so proto.getProtocol("
