Implement Endless scroll on ListView [closed]

by

implement the onscrolllistener() 

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;
    this.isScrollCompleted();
 }

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! ***/
        if(!isLoading){
             isLoading = true;
             loadMoreDAta();
        }
    }
}

as you implement and add this listener to your listview this will detect for the end of listview as scroll position was at end of list just get more data. And during the loading data you need one flag to load data at once when the scroll position goes to end. So if data is loading and during that time you scroll up then scroll down then it will not get more data for dupplication.
