I'm new to Android. My requirement is to load extra data & set to the list view, when scroll reaches to the bottom. I am able to call next data but my previous data is hiding. How to correct this?

 listView.setOnScrollListener(new OnScrollListener() {

                @Override
                public void onScrollStateChanged(AbsListView view,
                        int scrollState) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onScroll(AbsListView view,
                        int firstVisibleItem, int visibleItemCount,
                        int totalItemCount) {
                    // TODO Auto-generated method stub
                    if (listView.getLastVisiblePosition() == listView
                            .getAdapter().getCount() - 1
                            && listView.getChildAt(
                                    listView.getChildCount() - 1)
                                    .getBottom() <= listView
                                    .getHeight()) {
                        // scroll end reached

                        if (nextCall == null || nextCall == ""
                                || nextCall.equals("null")
                                || nextCall.equals("")) {

                        } else {

                            hostname=nextCall;

                            new ArticlesList().execute();

                        }

                        // Write your code here
                    }else{

                    }

                }
            });
            dialog.dismiss();
        } else {

            Toast.makeText(getActivity(), "Went wrong",
                    Toast.LENGTH_LONG).show();
            dialog.dismiss();
        }
